David Daney 4898c56010 Staging: Octeon: Free transmit SKBs in a timely manner 
If we wait for the once-per-second cleanup to free transmit SKBs,
sockets with small transmit buffer sizes might spend most of their
time blocked waiting for the cleanup.

Normally we do a cleanup for each transmitted packet.  We add a
watchdog type timer so that we also schedule a timeout for 150uS after
a packet is transmitted.  The watchdog is reset for each transmitted
packet, so for high packet rates, it never expires.  At these high
rates, the cleanups are done for each packet so the extra watchdog
initiated cleanups are neither needed nor triggered.
