History
Ruslan Ermilov 6ec31f009a Performance tuning. 
Moved the RX ring resyncing code to ste_rxeoc(), and only run it
if we were asked to POLL_AND_CHECK_STATUS, under DEVICE_POLLING.
(This significantly reduces the CPU load.)

Improved the RX ring resyncing code by re-checking if the head
is still empty before doing resyncing.  This mostly affects the
DEVICE_POLLING mode, where we run this code periodically.  We
could start checking with an empty head (well, an empty ring
even), and after doing a few iterations, the chip might write
a few entries, including the head, and we would bogusly consider
this case as requiring resyncing.  On a test box, this reduced
the number of resyncs done by a factor of 10.

In ste_txeof(sc), only reset the watchdog timer to zero when
the TX list is completely empty.

Converted ste_tx_prev_idx to a pointer -- faster.

Removed some bitrot.
