The netif_wake_queue() is called correctly (i.e. only on !txfull
condition) from net_tx().  So Unconditional call to the
netif_wake_queue() here is wrong.  This might cause calling of
start_xmit routine on txfull state and trigger tx-ring overflow.

This fix is ported from commit 662a96bd6f020782dfbdc0d0bd177c7dbb556687.

Applied.

Please reference commits by also making mention of the commit
log message header line.  This way when a patch is backported
into another tree, people can still find it even if the
SHA1 ID is different.  For exmaple, I fixed the above to

Thanks.
