--------------------------------

commit 57c942bc upstream.

When a tx_timeout fires, the PF attempts to recover by incrementally
resetting.  First we try a PFR, then CORER and finally a GLOBR.  If the
GLOBR fails, then we keep hitting the tx_timeout and incrementing the
recovery level and issuing dmesgs, which is both annoying to the user
and accomplishes nothing.

If the GLOBR fails, then we're pretty much totally hosed, and there's
not much else we can do to recover, so this makes it such that we just
kill the VSI and stop hitting the tx_timeout in such a case.
