6ceb40baa9 Fix link state handling in bfe(4).
o conversion to callout(9) API.
 o add a missing driver lock in bfe_ifmedia_sts().
 o use our callout to drive watchdog timer.
 o restart Tx routine if pending queued packets are present in
   watchdog handler.
 o unarm watchdog timer only if there are no queued packets.
 o don't blindly reset phy and let phy driver handle link change
   request in bfe_init_locked().
 o return the status of mii_mediachg() to caller in
   bfe_ifmedia_upd(). Previously it always returned 0 to caller.
 o add check for IFF_DRV_RUNNING flag as well as IFF_DRV_OACTIVE
   in bfe_start_locked().
 o implement miibus_statchg method that keeps track of current
   link state changes as well as negotiated speed/duplex/
   flow-control configuration.
   Reprogram MAC to appropriate duplex state. Flow-control
   configuration was also implemented but commented out at the
   moment. The flow-control configuration will be enabled again
   after we have general flow-control framework in mii layer.

6daee769f4 Add suspend/resume support. Unlike many other NIC drivers,
bfe_init_locked() wasn't sufficient to bring the chip back to life, it also
required a call to bfe_chip_reset() during resume.

f99da8e0d8 Re-revert back to rev 1.8:
- Reduce the number of RX and TX buffers bfe uses so that it does not use more
  bounce buffers than busdma is willing to allow it to use

See if_bfe.c for comments on why this is now safe to do.

678d2a9a8c 1. Make sure that the TX and RX descriptor rings are 4096 byte aligned.
Also use BUS_DMA_ALLOCNOW to be on the safe side.

2.  Look for the Descriptor Error, and Descriptor Protocol Error flags from
    the card, and down the interface if we detect either.

#1 (along with fixes to busdma) makes sure that this card works in all
memory situations.  Prior to this change, it was just luck that 512 count
RX/TX lists were properly aligned.  Now we can use any size of RX/TX lists
and still have them properly aligned.

#2 ensures that we don't get into an endless interrupt storm if busdma fails
us.  Descriptor Protocol Error would occur if we misaligned the TX/RX rings,
and Descriptor Error would occur if we tried to give the card descriptors
or rings with addresses > 1G.  Trying to reinitialize the card isn't going
to fix these errors, hence we don't try.

5511c4d6dc Fix three more bugs in bfe:
- Fix bfe_encap so that it will pass the address of the mbuf back up to its
  caller if/when it modifies it, as it does when doing a m_defrag on a mbuf chain.
- Make sure to unload the dmamap for ALL fragments of a packet, not just the first
- Use BUS_DMA_NOWAIT for all bus_dmamap_load calls so that the allocation of the
  map is not delayed - this driver is not set up to handle such delays.
- Reduce the number of RX and TX buffers bfe uses so that it does not use more
  bounce buffers than busdma is willing to allow it to use

With these changes, the driver now works properly for a user with a 2GB system,
and it also works on my system when the acceptable address range is lowered to 128MB.
Previously, both of these setups would act up after a few minutes of activity.

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

60c38bde75 Releasing TX/RX descriptor dmamaps during device detachment instead of
doing that in bfe_stop().

This should fix a panic recently reported on -current occuring when taking
device down then up.  In the original implementation, an "ifconfig bfe0 down"
triggers bfe_stop(), which also destroys all TX/RX descriptor dmamaps. Hence
the subsequent "ifconfig bfe0 up" would force the device to use those
already-released dmamap and thus panic the kernel.

f16b4811d2 Locking cleanups to remove the need for a recursive mutex
o Instead of locking and unlocking all over the place, use
	  lock assertions to make certain that the bfe lock is held
	  where necessary.
	o Create locked and unlocked versions of bfe_init and bfe_start. These
	  functions can be called from outside the module and by functions
	  within the bfe module. The calls from outside the module don't
	  hold the bfe lock so the unlocked versions called by these functions
	  simple obtain the bfe lock and call the locked version.

- Fix a typo (scp) in the locking macros that only worked because in all the
  instances in which it was called the softc pointer happened to be named 'sc'.

- Mark the interrupt MPSAFE

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.
