CVS commit: src/sys/dev/marvell

Module Name:    src
Committed By:   msaitoh
Date:           Mon Feb  3 05:56:23 UTC 2014

Modified Files:
        src/sys/dev/marvell: if_mvgbe.c

Log Message:
 Carefully set IFF_OACTIVE in mvgbe_start(). Even if mvgbe_encap()
returns other than 0, the TX ring might not full. Check whether
the TX ring has one or more packets. If the ring is empty,
dont' set IFF_OACTIVE because an TX complete interrupt never
occur and IFF_OACTIVE flags is left. The interface's timer
isn't reset, so a device timeout desn't occur.

 Fixes a bug that IFF_OACTIVE flag is left on heavy load.
Part of PR#48568.
