sys/dev/pci : if_msk.c
Log message:
push rxed packets to the stack once per interrupt (per port)
pushing to the stack on every packet completion interacts badly
with the backpressure mechanism in ifiq_input when you rx more than
8 or so packets per interrupt.
while here move to ifiq_input and apply backpressure before we start
dropping in software.
the problem was found by olivier taibi and reported on bugs@
i tested this on an overdrive 1000 which uses msk for its onboard nic
