[PATCH 7/7 net-next] tg3: Change default number of tx rings to 1.

["Michael Chan" <mchan@broadcom.com>]

Hardware tx scheduling can cause some starvation of a tx ring with small
packets if other tx rings have jumbo or TSO packets.  The default setting
of 1 TX ring gives the best overall performance in many common traffic
scenarios.  The user can change it using ethttol -L if desired.

Update version to 3.125.
