[Bug 414724] [NEW] wl driver (Broadcom) does not receive ARP packets (broadcasts)

[David Monniaux]

Public bug reported:

It seems that the wl driver in kernel-2.6.28-14 restricted modules
(x86_64) does not receive ARP broadcast packets (possibly, it does not
receive broadcast packets at all).

Symptom: have two hosts A (your machine with wl and Broadcom) and B on
the same Ethernet network. Boot them up. Do *not* connect or ping B from
A. At this point, the ARP cache on B does not know the MAC address for
A. Try ssh from B to A, it won't find the host. Do a single ping from A
to B (which creates an entry for A in B's ARP cache). ssh from B to A
then works.

The problem can of course be worked around by hardcoding the MAC address
of the Broadcom/wl host in the ARP caches of the other machines on the
network, but this is quite unwieldy.

I suspect the driver does not process Ethernet broadcasts, but I may be
wrong (I haven't checked).
