svn commit: r225892 - head/sys/mips/mips

[Adrian Chadd]

Hi all,

I've tried jc's patch. The hand-wavy, brief summary when tested on my
hostap (mips):

* when doing single-stream, one way TCP tests (where it thus needs
TX/RX traffic to occur), I get 100% CPU utilisation - 50% interrupt,
50% system, but the total interrupt rate isn't too high. It's much
higher than without his patch. I'll go digging later to see what's
going on.
* when doing single-stream, one way UDP (ie, only RX traffic, no TX
besides beacons and occasional other stuff), the system utilisation is
better (70% system, ~ 2% interrupt). But I still see interrupt latency
issues. I don't know whether it's because interrupts are missed or
they're not missed but the scheduling doesn't occur until after wait
has returned. I'll have to do some further digging.
