[PATCH] myri10ge: write as 2 32-byte blocks in myri10ge_submit_8rx
In the myri10ge_submit_8rx() routine, write the 64 byte request block as 2 32-byte blocks so that it is handled by the hardware pio write handler if write-combining is enabled. Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
