sys/dev/em if_em.c if_em.h
Log:
This delta addresses some users experiencing watchdogs under load with
the last driver version. I suspect sheduling to be at the bottom of it,
but this version fixes it by:
- Making FAST interrupt handling off by default, if you want
to use it #define EM_FAST_IRQ in the Makefile.
- Add dual locks, one for the TX subsystem, the other CORE
for things like init and interface managment.
- Add cleaner MSI/X setup code.
- If using FAST interrupts there is now a mechanism in the
watchdog routine to kick off TX cleanups if they have not
been scheduled.
I think everyone will be happier with this change.
