Currently the driver issues 2 mmio reads to figure out the number of transmitted packets and clean them. We can get rid of the expensive reads since BIT 31 of the Tx descriptor can be used for that. We can also remove the budget counting of Tx completions since all of the descriptors are not deliberately processed. Performance numbers using pktgen are: size pre-patch(pps) post-patch(pps) 64 362483 427916 128 358315 411686 256 352725 389683 512 215675 216464 1024 113812 114442 Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S.
