fcb62a8b01 Add hack to pass controller specific information to phy driver.
Unlike most other PHYs there is no easy way to know which media
type the PHY supports on Marvell PHYs. MIIF_HAVEFIBER flags is now
passed via bus-specific instance variable of a device. While I'm
here add 88E1112 specific work around to set SIGDET polarity low.
Many thanks "Eugene Perevyazko <john <> dnepro dot net>" who kindly
gave remote access to system with DGE-560SX.

1a01dae1b9 Some fiber PHY(88E1112) does not seem to set resolved speed so

44d9075392 Backout r193289. r193289 restored page select bits to previous
value instead of blindly resetting it to 0. However, it seems page
select bits of some 88E1116 PHY is initialized to invalid one such
that restoring page select bits after programming broke MII
register access. The correct solution would be reset page select
bits to 0 in PHY attach stage but it would require more testing.
Since we're in BETA stage such a change would be dangerous so just
back it out.
This change should fix nfe(4) breakage on NVIDIA MCP55.

745ef56af2 Add driver support for 88E3016 PHY which is found on Marvell Yukon
FE+ controller. Due to the severe silicon bugs for Yukon FE+,
88E3016 seems to require more workarounds. However I'm not sure
whether the workaround is PHY specific or only applicable to Yukon
FE+. The datasheet for the PHY is publicly available but it lacks
several details for the workaround used in this change. The
workaround information was obtained from Linux. Many thanks to
Yukon FE+ users who helped me add 88E3016 support.

b435227b7d Some 88E1149 PHY's page select is initialized to point to other
bank instead of copper/fiber bank which in turn resulted in
wrong registers were accessed during PHY operation. It is
believed that page 0 should be used for copper PHY so reinitialize
E1000_EADR to select default copper PHY.
This fixes link establishment issue of nfe(4) on Sun Fire X4140.

OpenBSD also has similimar patch but they just reset the E1000_EADR
register to page 0. However some Marvell PHYs((88E3082, 88E1000)
don't have the extended address register and the meaning of the
register is quite different for each PHY model. So selecting copper
PHY is limited to 88E1149 PHY which seems to be the only one that
exhibits link establishment problem. If parent device know the type
of PHY(either copper or fiber) that information should be notified
to PHY driver but there is no good way to pass this information yet.

694c651803 This is a rewritten driver for the SMSC LAN91C111. It's based in part on the
sn(4) driver and also looking at newer drivers.  The reason for the rewrite is
to support MII and to try and resolve some performance issues found when trying
to use the sn(4) driver on the Gumstix network boards.

For reference, the SMSC LAN91C111 is a non-PCI ethernet part whose lineage
dates back to Ye Olde Days of ISA.  It seems to get some use in the embedded
space these days on parts lacking on-board MACs or on-board PCI controllers,
such as the XScale PXA line of ARM CPUs.

This also includes a driver for the SMSC LAN83C183 10/100 PHY.

648bfbe6a7 Add support for RealTek RTL8211B(L) PHY. It's based on the patch
made by Michael Eisele and the patch was slightly modified by me.
With this change several NVIDIA ethernet controllers(e.g. MCP61)
works.

RTL8211B(L) is RealTek's new gigabit PHY. The PHY has several
features including crossover correction, polarity correction as
well as supporting triple speed(10/100/1000bps). Data transfer
between MAC and PHY is via RGMII for 1000baseT, MII for
10baseT/100baseTX.
Unfortunately, RealTek used the same model number for RTL8211B(L)
PHY so there is no way to discriminate between RTL8211B(L) and its
predecessors. ATM RTL8211B uses revision number 2 so checking the
revision number seems to be only way to identify it.

2f9f08b635 - Take advantage of mii_phy_add_media() for adding media and setting
sc->mii_anegticks according to whether the respective BGE chip
  supports Fast Ethernet only or also Gigabit Ethernet.
- At least the BGE chips I've tested with wedge when isolating them
  so document this as the reason for setting MIIF_NOISOLATE and
  remove the unused (and partially even #ifdef'ed out) isolation
  related code. Add code that panics if we encounter a non-zero MII
  instance as generally there's no way a PHY requiring MIIF_NOISOLATE
  can be handled gracefully in a multi-PHY configuration (it's ok for
  the internal PHY of single-PHY-only-NIC to not support isolation
  though).
- Additionally set MIIF_NOLOOP as loopback doesn't seem to work
  either and remove the #ifdef'ed out code for adding respective
  media. The MIIF_NOLOOP flag currently triggers nothing but
  hopefully will be respected by mii_phy_setmedia() later on.

f7a66f06ec Restore support for the 5706C bce(4) phy that was broken during the
addition of SerDes support.  According to the docs, the 5706C and 5708C
phys are supposed to use the same MII model that is separate from the
SerDes parts, but the 5706C actually uses the MII model of the SerDes
parts.  To fix this, readd the old 5706C entry to miidevs and add a
special check in brgphy_probe() for phys that match the 5706C ID.  If
the phy is supported by the gentbi(4) driver, then it's a SerDes phy, so
we fail the probe and let gentbi(4) grab it.  Otherwise, it's a 5706C phy,
so we let brgphy(4) grab it.

6d2b26f4a0 Fix problem with RTL8201L PHY. From submitter:
Bugfix for the Realtek PHY driver... an RTL8201L standalone PHY
    needs different handling than the integrated ones in terms of
    speed detection.  There was a bogus test based on the parent
    device driver name string controlling which speed register to
    query.  That test began failing when the rl driver was split into
    separate rl and re drivers some time ago.  Apparently nobody ever
    noticed because the buggy code only executes if NWAY negotiation
    failed.  Since we happen to be testing with an ancient dumb hub
    rather than a modern switch, we found it.

    To fix it all, have the attach() routine notice whether we're
    dealing with an integrated PHY or an RTL8201L and store that info
    in a struct accessible to the status() routine that needs to know
    which register to query.

I touched up the fixes because they were relative to RELENG_6 and to
bring a few nits into line with style(9).

9bcdfcae43 - In miibus_attach() remove IFM_IMASK from the dontcare_mask of the
ifmedia_init() invocation. IFM_IMASK makes only sense here when all of
  the maxium of 32 PHYs on each one MII bus support disjoint sets of media,
  which generally isn't the case (though it would be nice if we had a way
  to let NIC drivers indicate that for the few card models where the PHY
  configuration is known/fixed and IFM_IMASK actually makes sense).
- Add and use a miibus_print_child() for the bus_print_child method which
  additionally prints the PHY number (which actually is the PHY address)
  so one can figure out the media instance <-> PHY number mapping from the
  PHY driver attach output. This is intented to be usefull in situations
  where the addresses of the PHYs on the bus are known (f.e. of internal/
  integrated PHYs) so one can feed the appropriate media instance number
  to ifconfig(8) (with the upcoming change for ifconfig(8)).
  This is more or less inspired by the NetBSD mii_print().

     negotiation cycle as part of the reset.
  2) During reset and auto-negotiation, the BMCR will clear the reset
     bit before the process is complete. It will return 0 until the
     process is complete and it's safe to access the PHY again.

  This is the first of two changes required to make the combination of

ed510fb04f Add support for the RealTek 8169SC/8110SC and RTL8101E devices. The
latter is a PCIe 10/100 chip.

Finally fix the EEPROM reading code so that we can access the EEPROMs on all
devices. In order to access the EEPROM, we must select 'EEPROM programming'
mode, and then set the EEPROM chip select bit. Previously, we were setting
both bits simultaneously, which doesn't work: they must be set in the
right sequence.

Always obtain the station address from the EEPROM, now that EEPROM
reading works correctly.

Make the TX interrupt moderation code based on the internal timer
optional and turned off by default.

Make the re_diag() routine conditional and off by default. When it is
on, only use it for the original 8169, which was the only device that
that really needed it.

Modify interrupt handling to use a fast interrupt handler and fast
taskqeueue.

Correct the rgephy driver so that it only applies the DSP fixup for
PHY revs 0 and 1. Later chips are fixed and don't need the fixup.

f0e531572d DP83840A on hme(4) don't advertise their media capabilities themselves
properly. This causes the autonegotiation to e.g. never establish a
100baseTX full-duplex link. The solution to this problem is to manually
write the capabilities from the BMSR to the ANAR every time a media
change occurs, even when already in autonegotiation mode.
The NetBSD way of doing this is to set their MIIF_FORCEANEG flag in the
NIC driver. This causes mii_phy_setmedia() to call mii_phy_auto() (which
will set the ANAR according to the BMSR) even when the PHY alread is in
autonegotiation mode. However, while doing the same on FreeBSD (which
involves porting the MIIF_FORCEANEG flag and converting nsphy.c to use
mii_phy_setmedia()) fixes autonegotiation, using mii_phy_setmedia()
causes this driver to no longer work properly in the other modes.
Another drawback of that approach is that this will also force writing
the ANAR on other PHYs whose drivers use mii_phy_setmedia() and which
are used with a NIC whose driver sets MIIF_FORCEANEG (e.g. hme(4) is
known to be used together with 3 different PHYs while only the DP83840A
require this workaround).
So instead of moving to MIIF_FORCEANEG, just call mii_phy_auto() in
nsphy_service() unconditionally when hanging off of a hme(4) and serving
a media change

This is part 1/2 of fixing autonegotiation on hme(4) using DP83840A PHYs.

b9f78d2b4a Add a device driver for the Broadcom BCM4401 ethernet controller,
written by Stuart Walsh and Duncan Barclay (with some kibbitzing by
me). I'm checking it in on Stuart's behalf.

The BCM4401 is built into several x86 laptop and desktop systems. For the
moment, I have only enabled it in the x86 kernel config because although
it's a PCI device, I haven't heard of any standalone NICs that use it. If
somebody knows of one, we can easily add it to the other arches.

This driver uses register/structure data gleaned from the Linux
driver released by Broadcom, but does not contain any of the code
from the Linux driver itself. It uses busdma.

a94100fa9b Take the support for the 8139C+/8169/8169S/8110S chips out of the
rl(4) driver and put it in a new re(4) driver. The re(4) driver shares
the if_rlreg.h file with rl(4) but is a separate module. (Ultimately
I may change this. For now, it's convenient.)

rl(4) has been modified so that it will never attach to an 8139C+
chip, leaving it to re(4) instead. Only re(4) has the PCI IDs to
match the 8169/8169S/8110S gigE chips. if_re.c contains the same
basic code that was originally bolted onto if_rl.c, with the
following updates:

- Added support for jumbo frames. Currently, there seems to be
  a limit of approximately 6200 bytes for jumbo frames on transmit.
  (This was determined via experimentation.) The 8169S/8110S chips
  apparently are limited to 7.5K frames on transmit. This may require
  some more work, though the framework to handle jumbo frames on RX
  is in place: the re_rxeof() routine will gather up frames than span
  multiple 2K clusters into a single mbuf list.

- Fixed bug in re_txeof(): if we reap some of the TX buffers,
  but there are still some pending, re-arm the timer before exiting
  re_txeof() so that another timeout interrupt will be generated, just
  in case re_start() doesn't do it for us.

- Handle the 'link state changed' interrupt

- Fix a detach bug. If re(4) is loaded as a module, and you do
  tcpdump -i re0, then you do 'kldunload if_re,' the system will
  panic after a few seconds. This happens because ether_ifdetach()
  ends up calling the BPF detach code, which notices the interface
  is in promiscuous mode and tries to switch promisc mode off while
  detaching the BPF listner. This ultimately results in a call
  to re_ioctl() (due to SIOCSIFFLAGS), which in turn calls re_init()
  to handle the IFF_PROMISC flag change. Unfortunately, calling re_init()
  here turns the chip back on and restarts the 1-second timeout loop
  that drives re_tick(). By the time the timeout fires, if_re.ko
  has been unloaded, which results in a call to invalid code and
  blows up the system.

  To fix this, I cleared the IFF_UP flag before calling ether_ifdetach(),
  which stops the ioctl routine from trying to reset the chip.

- Modified comments in re_rxeof() relating to the difference in
  RX descriptor status bit layout between the 8139C+ and the gigE
  chips. The layout is different because the frame length field
  was expanded from 12 bits to 13, and they got rid of one of the
  status bits to make room.

- Add diagnostic code (re_diag()) to test for the case where a user
  has installed a broken 32-bit 8169 PCI NIC in a 64-bit slot. Some
  NICs have the REQ64# and ACK64# lines connected even though the
  board is 32-bit only (in this case, they should be pulled high).
  This fools the chip into doing 64-bit DMA transfers even though
  there is no 64-bit data path. To detect this, re_diag() puts the
  chip into digital loopback mode and sets the receiver to promiscuous
  mode, then initiates a single 64-byte packet transmission. The
  frame is echoed back to the host, and if the frame contents are
  intact, we know DMA is working correctly, otherwise we complain
  loudly on the console and abort the device attach. (At the moment,
  I don't know of any way to work around the problem other than
  physically modifying the board, so until/unless I can think of a
  software workaround, this will have do to.)

- Created re(4) man page

- Modified rlphy.c to allow re(4) to attach as well as rl(4).

Note that this code works for the sample 8169/Marvell 88E1000 NIC
that I have, but probably won't work for the 8169S/8110S chips.
RealTek has sent me some sample NICs, but they haven't arrived yet.
I will probably need to add an rlgphy driver to handle the on-board
PHY in the 8169S/8110S (it needs special DSP initialization).

  the driver only advertises 1000BaseT as the supported media type
  and enable autonegotition.

- Only set Master/Slave on the 5701.
  Obtained from Broadcom Linux driver.
