Okay. Recently, David O'Brien handed me an Intel 10/100 Cardbus NIC,
which uses the 21143-PB chip. It's a non-MII card (has a Quality Semi
symbol PHY). Unfortunately, it looks like Intel has taken a few shortcuts
with this card: the serial EEPROM doesn't contain any useful information.
Instead, th
3Com has yet another revision of the Tornado chipset floating around out
there on newer 3c905C adapters. Supposedly, these are marked as 3c905CX
and have become available within the last couple of months. I've seen
some noise on the Linux mailing lists that seems to indicate that some
driver mods
nt out the test for the IFF_PROMISC flag.)
This will enable the workaround all the time and allow the receiver bug
to be detected and handled properly.
Compile a new kernel with this change and see if the problem persists.
Report back your findings (one way or the other) so that I'll know
nreasonable to
allow backwards compatibility in the kernel code either.
