Log Message:
Don't destroy the dma maps if we're not disabling the adapter, avoids
a KASSERT() when bus_dmamap_destroy() is called from interrupt
context via bge_watchdog()
Set IFF_OACTIVE only when bge_encap() fails on adapter ressource shortage.
Otherwise we may set IFF_OACTIVE while no transmit is in progress, and
nothing will clear it.
If bus_dmamap_load_mbuf() fails with EFBIG, m_defrag() the chain and retry.
Refine the check for the 4GB boundary workaround (a fragment should also
not cross the boundary), and do it only for TSO.
If bge_encap() fails and didn't set IFF_OACTIVE, drop the packet.
Bring in more hardware bug workarounds from freebsd.
With these it seems that a BCM5720 A0 can survive a few hours of internet
load with TSO4 enabled.
