Hi, i'm having many dropped packages in all my physical interfaces,
are there any known fixes?, the module used is bnx2 (no usefull
parameters shown in modinfo). This host is running SLES10 SP2 (think
of opensuse 10.3, more or less) under the xen hypervisor. The list of
devices is listed below..

Usually this is a memory related problem. You can try reducing
txqueuelen:1000 to something like 500.

Of course, if you connect all these interfaces to the same switch/hub
you could also cause an arp storm. You are dropping packets
on interfaces that don't even have IPs, so its pretty likely arp related.

Is the switch/hub gigabit capable and auto-negotiating?
