 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.
