Enable RPS on eth0 on labstores
During recent Labs NFS overload situations, we've seen timeouts on
CPU #0 and ksoftirqd/0 consuming high amount of CPU. A quick look
in /proc/interrupts reveals why: all network interrupts (and
megasas as well) are being handled by CPU #0. No irqbalance running
either.
This naive patch enables Receive Packet Steering (RPS), which will
hopefully improve the situation, but may need further tweaking.
