sys/dev/mxge if_mxge.c
Log:
Much to my surprise, IFQ_DRV_DEQUEUE() can return a null mbuf even if
!IFQ_DRV_IS_EMPTY(). Taking this into account, I re-structured the
transmit routine so as to avoid adding another if/then in the
critical path.
Thanks to brueffer for showing my how to test with altq/pf.
