PATCH: Pcmcia/Cardbus/xircom_tulip in 2.4.0-test10.

[Ballabio_Dario]

In order to have the xircom_tulip pcmcia cardbus working again with 
recent kernels, it is necessary to specify:
 
ifconfig eth0 -multicast

Moreover if the card is configured by itself into the kernel 
(i.e. with the default ne2000 pcmcia support removed),
the enclosed patch is required as well.

Cheers,

Can you try the test11-pre2 patch?  It includes a bugfix to xircom_tulip
from Andrea.

ftp://ftp.??.kernel.org/pub/linux/kernel/testing/

?? == your country code, such as "us", "fr", etc.

RE: PATCH: Pcmcia/Cardbus/xircom_tulip in 2.4.0-test10.

[Ballabio_Dario]

I just tested test11-pre2 and there is no improvement. I still need to issue
the
ifconfig eth0 -multicast
and just after it the xircom_tulip card begins to work.

edit linux/arch/i386/kernel/traps.c.  move the bust_spinlocks function,
AND the 'extern ...timer_list' line near it above the CONFIG_X86_IO_APIC
ifdef.

Andrea's fix doesn't actually solve the problem; it merely changes the
set of working configurations to a set that includes Andrea's setup.
I don't know whether the size of the working set gets larger or
smaller.

There is something fundamentally broken/weird about how the receive
filter works on the Xircom cards.  It is at least deterministic, but
different network configurations behave very differently and I haven't
been able to figure out the logic.  One version of the driver will
work perfectly for everyone that uses DHCP... another version will
work fine for people who specify a static IP address... another
version will work for people who use Red Hat's network configuration
script but not the default PCMCIA script.  The best I've been able to
figure out, is that whether a call to set_rx_mode() will work or lock
up the card depends on the history of what has gone on before (whether
the card has had traffic through it), where the rx filter setup frame
goes in the transmit ring, the alignment of the frame, and how many
times set_rx_mode() has been called.  Certain combinations work, other
combinations don't.

The effect of "ifconfig eth0 -multicast" (which should be a no-op) is
that it calls set_rx_mode() with the same set of parameters it was
called with before.  Doing this one or more times may kick the card so
that it starts working.  The number of times is constant for a given
network configuration, and varies between 0 and 3.

I wasted a lot of time trying to figure out the rules for when
set_rx_mode() would work and eventually gave up; I'm waiting for
Xircom to give me an explanation.

If you want another datapoint, this doesn't help on my own Xircom card.
The only way to make it receive packets while not in promisc mode was
to add back the "+ 4" to the buffer address in the descriptor -- reverting
one of the changes that went into 3.1.21.

Anything else I've tried didn't help: filling up all slots with my MAC,
adding them at the end of the list, at the beginning, as little/big endian,
in reverse order... you name it. The "+ 4" however made it work reliably.

The card is a Xircom RealPort CardBus Ethernet 10/100, code RBE-100. This
is the lspci entry for it:

20:00.0 Class 0200: 115d:0003 (rev 03)
        Subsystem: 115d:0181
        Flags: bus master, medium devsel, latency 64, IRQ 11
        I/O ports at 0200
        Memory at a000d000 (32-bit, non-prefetchable)
        Memory at a000c000 (32-bit, non-prefetchable)
        Expansion ROM at a0008000 [disabled]
        Capabilities: [dc] Power Management version 1

Thanks,
Ion
