Subject: [PATCH] drivers/net: remove network drivers' last few uses of IRQF_SAMPLE_RANDOM
feature-removal-schedule.txt says a new /dev/random entropy model is planned
(for July 2009). Until then, this patch removes the few remaining uses of
IRQF_SAMPLE_RANDOM from drivers/net/*. 12 network drivers are affected, one
more than last year (netxen_nic_main.c). If idle servers need more entropy,
they ought to use a hardware RNG or an entropy-gathering userspace daemon.
