306a209024 Fix the code so that it no longer on alpha refers to the now nonexistent
pci_cvt_to_bwx.

This doesn't necessarily make bge(4) now actually *work* on an alpha.
It loads, configures, and then about 30 seconds later, my XP1000 hard
freezes. But, hey, it's a start.

ea13bdd522 Follow the lead of recent changes in the 3com Linux driver by
disabling memory write invalidate unconditionally.  It looks like
they've decided that MWI just doesn't work with these devices.
Also, remove now-irrelevant code that set PCI write boundary values
based on the cache line size.

b1265c1a98 Add support for the BCM5703x chips. I do not have one of these
cards to test; however the submitter reports that this patch works
with the on-board interface on the IBM x235 server.

470bd96a07 Recognize the Altima AC9100 chip, which is used in current versions
of the Netgear GA302-T.  I changed the symbolic names in the
submitter's patch to reflect the part number of the chip instead
of the board.

5ddc57942f Disable hardware checksum offloading of IP fragments in the bge
driver.  I tried a few obvious experiments, but was unable to make
the 3c996B-T generate correct UDP checksums for transmitted fragmented
packets.  I'm not so sure the device is even capable of it.

This fixes NFS over UDP.

e255b776bc 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.

a1d52896af 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.)

98b28ee5b4 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.

95d674824f Add device driver support for the Broadcom BCM570x family of gigabit
ethernet controllers. This adds support for the 3Com 3c996-T, the
SysKonnect SK-9D21 and SK-9D41, and the built-in gigE NICs on
Dell PowerEdge 2550 servers. The latter configuration hauls ass:
preliminary measurements show TCP speeds of over 900Mbps using
only normal size frames.

TCP/IP checksum offload, jumbo frames and VLAN tag insertion/stripping
are supported, as well as interrupt moderation.

Still need to fix autonegotiation support for 1000baseSX NICs, but
beyond that, driver is pretty solid.
