pasemi_mac: workaround for erratum 5971
pasemi_mac: workaround for erratum 5971
Implement workarounds for erratum 5971, where L2 hints aren't considered
properly unless the way hint is enabled on the interface. Since L2 isn't
setup to dedicate a way to headers, we need to reset the packet count
by hand so it won't run out of credits.
