Modified files:
sys/pci if_ti.c
Log:
Add a test to ti_encap() to try and prevent the transmit producer index
from ever catching up to the transmit consumer index. We can't let this
happen because ti_txeof() depends on the assumption that producer == consumer
means the ring is empty, and producer != consumer means the ring has some
number of active descriptors in it.
