1a2d5f38b0 Add support for the Broadcom BCM5901 and BCM5901 rev A2 chips.
These are 10/100 only NICs found on the IBM Thinkpad R40E and
G40. These seem to be based on the BCM5705 MAC but with a PHY
that doesn't support 1000Mbps modes.

4a2cb9ec2f The BCM5704 ASIC has a smaller mbuf space than the 5700/1/2/3. Failure
to configure this correctly yields many watchdog timeouts even on lightly
loaded machines. This is a common complaint from users with Dell 1750
servers with built-in dual 5704 NICs.

73cc57c6c7 Silence unwanted 'gigabit link up' messages: do not treat the
BGE_MACSTAT_MI_COMPLETE bit in the MAC status register as a link
change indicator. We turn this bit on now because some of the newer
chips need it, but it usually just means that reading/writing
an MII/GMII register has completed, not that a link change has
occured.

3268777224 Set the BGE_RX_MTU register correctly so that we can receive slightly
larger than normal frames, to account for the case where a bge(4) NIC
is used with VLANs. Since we set the IFCAP_VLAN_MTU flag, we must allow
reception of frames up to 1522 bytes in size rather than 1518.

Note that it is possible to work around this bug by doing:

# ifconfig bge0 mtu 1504

prior to configuring any VLAN interfaces.

e611c41699 Add support for the BCM5705 and its ilk. Changes:
- 5705 doesn't support jumbo frames
- Statistics must be read from registers
- RX return ring must be capped at 512 entries
- Omit initialization of certain device blocks
- Acknowledge link change interrupts by setting the 'link changed'
  bit in the status register (used to have no effect)
- Remember to toggle the MI completion bit too
- Set the mbuf low watermark differently (on-chip memory buffers,
  not BSD mbufs)
- Don't enable Ethernet@WireSpeed feature for certain 5705 chip revs
- Add additional PCI IDs for 5705 and 5782 parts
- Add a forgotten 5704 PCI ID

Most changes ripped kicking and screaming from the Broadcom linux driver.
Thanks to Paul Saab for sanity testing. (My lack of sanity has been

4d41e2d69f Squelch spurious "gigabit link up" messages generated on some fiber NICs
(mainly the 3Com 3c996B/BCM5701).

For some reason that I don't fully understand, the 5701 signals PCS
encoding errors as though they were link change events, i.e. the 'link
state changed' bit in the status word of the status block is updated
and an interrupt is generated. This would cause the bge_tick() function
to be invoked and a "gigabit link up" message to be printed on the console.

To avoid this, the interrupt handler now checks the MAC status register
when a link change interrupt is triggered, and it will only call the
bge_tick() function if the 'PCS encoding error detected' bit is clear.
(This change should have no effect on copper NICs since this bit can
only ever be set in TBI mode. I do not know how it affects 5704 NICs
with a BCM8002 SERDES PHY.)

Special thanks to: Sherry Rogers at UCB for allowing me access to one
of their traffic monitor boxes so I could diagnose this problem.

f35cb3a504 Don't reference the maxlen and flags fields in the ring control blocks
as separate 16-bit entities.  Some of the ring control blocks are
in NIC memory, so they must be referenced using 32-bit accesses.
Smaller accesses have been observed to fail under some conditions.
This caused the rings to be set up wrong, leading to writes by the
card outside of the intended bounds of the rings.  This problem was
diagnosed by Michael Barthelow.  Don Bowman submitted a patch which
fixed the problem using a slightly different approach.

Reference ring control blocks in NIC memory using a pointer to
volatile.

b1ccf3cc04 Work around what appears to be a chip bug in the BCM5701 that shows
up when operating in PCI-X mode.  For some received packets there is
data corruption in the first few bytes in that case.  Aligning the
packet buffer eliminates the corruption.  With this fix, the code
that offsets the packet buffer up by 2 bytes to align the payload is
disabled for BCM5701s operating in PCI-X mode.  On the i386, which
permits unaligned accesses, the payload is left unaligned.  On other
platforms, the packet is copied after reception to force alignment
of the payload.  Obviously, this work-around reduces performance in
those cases (BCM5701 plus PCI-X) where it is in effect.

707ff463e2 Try to sort out the correct way to generate async link state change
interrupts. This is a bit harder than it needs to be because there's
more than one way to generate link attentions, at least one of which
does not work on the BCM5700, but does on the 5701.

For the 5701, we can safely use the 'link changed' bit in the status
block, and we enable link change attentions in the mac event register.
For the 5700, we have to use MII interrupts, which require checking
the MAC status register rather than the status block. This requires
doing an extra register access on each interrupt which I'd prefer to
avoid, but them's the breaks. Testing with both a 3c996-T and 3c996B-T
shows that we do in fact detect the link going up and down properly
on cable insertions/disconnections.

Also, avoid twiddling the autopoll enable bit in the MI mode register
when doing a PHY read. I think this coupled with the other changes
will stop the interrupt storms Paul Saab has been harassing me about.
Manually setting the link to 100baseTX full duplex seems to work ok
for me. (I'm typing over the 3c996B-T right now.)

Lastly, teach the driver how to recognize a 3c996B-SX by checking
the hardware config word in the EEPROM in order to detect the media.
We attach 5701 fiber cards correctly now, but I haven't verified that
they send/receive packets yet since I don't have a second fiber
interface at home. (I know that fiber 5700 cards work, so I'm
keeping my fingers crossed.)

7b860ddffd Teach the bge driver about the BCM5701 (specifically, the 3Com
3c996B-T, with the 5701 rev B5 ASIC). One thing that confuses me
still is that the 'link state change' bit in the status block seems
to change state an awful lot. I have a workaround for this in place
now, but it needs more investigation. For the moment though, this
is enough to get the driver to work with this card.
