Modified files:
sys/pci if_ti.c if_tireg.h
Log:
Add a transmit descriptor usage counter and use it to absolutely,
positively not let ti_encap() fill up the TX ring all the way and wrap
around. This fixes a potential transmit lockup where a really fast
machine (or particular TX traffic pattern) can overrun the end of the
ring.
