i've given up on the netdev_backlog_granularity approach, and as a
replacement i've modified specific network drivers to return at a safe
point if softirq preemption is requested. This gives the same end result
but is more robust. For the time being i've fixed 8193too.c and e100.c.
(will fix up other drivers too as latencies get reported)

this should fix the crash reported by P.O. Gaillard, and it should solve
the packet delay/loss issues reported by Mark H Johnson. I cannot see
any problems on my rtl8193 testbox anymore.

Last night when rebooting on R0 for the first time, my system locked up. It appears to have happened the first time trying to send/recv any real data over the e100 interface when ntp was starting up. Will try to investigate further a little later.
