eth1: too many iterations (6) in nv_nic_irq

Hi John,

We were not able to fully solve the problem, since the school opted to make
individual workstations out of the 'fat clients' (they were fairly
powerful). But the max_interrupt number that worked for me was 16 but I
would still hit the error when too many students access flash game sites.

I guess the best way for others to not encounter this problem is don't buy
this kind of lan card or maybe create a list of cards that gives this

Anyway, I am not connected with the project anymore, just lurking here to be
updated with whats the latest.
