[ofa-general] [PATCH 16/23] IB/ipath - iba6110 rev4 no longer needs recv header overrun workaround

[Arthur Jones]

iba6110 rev3 and earlier had a chip bug where
the chip could overrun the recv header queue.
rev4 fixed this chip bug so userspace no longer
needs to workaround it.  Now we only set the
workaround flag for older chip versions.
