pasemi_mac: further performance tweaks
pasemi_mac: further performance tweaks
Misc driver tweaks for pasemi_mac:
* Increase ring size (really needed mostly on 10G)
* Take out an unneeded barrier
* Move around a few prefetches and reorder a few calls
* Don't try to clean on full tx buffer, just let things
take their course and stop the queue directly
* Avoid filling on the same line as the interface is
working on to reduce cache line bouncing
* Avoid unneeded clearing of software state (and make the
interface shutdown code handle it)
* Fix up some of the tx ring wrap logic.
