Restore a sense of cleanly supporting multiple platforms. That is, place the LOCKing macros within the areas within if_wxvar.h that is set aside for them. Put any platform specific data also in those areas. For ease of maintenance purposes, merge in the OpenBSD version codebase here.

/* $FreeBSD$ */
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Finish silly offset differences that LIVENGOOD vs. WISEMAN registers have (so the !)$*!)$*!$ fiber LIVENGOOD now works too). 3. Ansify the source. So- we now suppor tthe PRO1000F and PRO1000T adapters.

static INLINE u_int32_t
_read_csr(wx_softc_ *sc, u_int32_t reg)
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Finish silly offset differences that LIVENGOOD vs. WISEMAN registers have (so the !)$*!)$*!$ fiber LIVENGOOD now works too). 3. Ansify the source. So- we now suppor tthe PRO1000F and PRO1000T adapters.

wx_mc_setup(wx_softc_t *sc)
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying.

#ifdef SMPNG
Implement MTX_RECURSE flag for mtx_init(). All calls to mtx_init() for mutexes that recurse must now include the MTX_RECURSE bit in the flag argument variable. This change is in preparation for an upcoming (further) mutex API cleanup. The witness code will call panic() if a lock is found to recurse but the MTX_RECURSE bit was not set during the lock's initialization. The old MTX_RECURSE "state" bit (in mtx_lock) has been renamed to MTX_RECURSED, which is more appropriate given its meaning. The following locks have been made "recursive," thus far: eventhandler, Giant, callout, sched_lock, possibly some others declared in the architecture-specific code, all of the network card driver locks in pci/, as well as some other locks in dev/ stuff that I've found to be recursive.

The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

* Seventh, allocate various sw structures...
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

wx_handle_link_intr(wx_softc_t *sc)
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this.

Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Get rid of the WX_XMIT_SMALL code- we've fixed that problem. Restructure the receive code so that it correctly chains receive descriptors together and handles the case that only a part of a packet is done at the time we get here.

ether_input(ifp, eh, mb);
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

WX_UNLOCK(sc);
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Restore a sense of cleanly supporting multiple platforms. That is, place the LOCKing macros within the areas within if_wxvar.h that is set aside for them. Put any platform specific data also in those areas. For ease of maintenance purposes, merge in the OpenBSD version codebase here.

There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

wx_txwatchdog(struct ifnet *ifp)
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.

Several things: 1. Pick up MII/PHY support for Livengood copper part (10/100/1000) from Parag Patel. It was a fairly complete but not quite platform independent job. 2. Finish silly offset differences that LIVENGOOD vs. WISEMAN registers have (so the !)$*!)$*!$ fiber LIVENGOOD now works too). 3. Ansify the source. So- we now suppor tthe PRO1000F and PRO1000T adapters.

wx_ifmedia_upd(struct ifnet *ifp)
Add first pass of the Intel Gigabit Ethernet (wiseman) driver. This driver seems relatively functional, but could use some souping up, particularly in the performance area. This has both NetBSD and FreeBSD attachment code and a fair amount of effort has been put into making it easy to port to different *BSD platforms. The basic design is a one tfd per mbuf transmit (with no transmit related interrupts- tfds are gc'd as needed). The receive ring uses a 2K buffer per rfd with a +2 byte adjust for the ethernet header (so the payload is aligned). There's support that *almost* works for doing large packets- the rfd chaining code works, but there's some problem with getting good checksums at the IP reassembly level (ditto for doing short tfd's too). The chip has support for TCP checksums insertion for transmit and TCP checksum calculation on receive (for both you have to do some appropriate backoff && twiddling), but this isn't in place. This is nearly entirely reverse engineered from the released Intel driver, so there's a lot of "We have to do this but do not know why" stuff. There is somebody who has the chip specs who works in FreeBSD but they're being a bit standoffish about even sharing hints which is somewhat annoying. It's also apparent that all I had to work with were the first rev boards. This driver has been lightly tested on intel && alpha, but only point-to-point. There may be some issues with switches- use of boot time environment variables that override EEPROM settings (e.g., 'set wx_ilos=1' which inverts the sense of optical signal loss) may help with this. I had this out for review for three weeks, and nobody said anything negative or positive, ergo, this checkin has no 'reviewed by' field which I would have preferred.
