bnxt_en: Optimize doorbell write operations for newer chips. Older chips require the doorbells to be written twice, but newer chips do not. Add a new common function bnxt_db_write() to write all doorbells appropriately depending on the chip. Eliminating the extra doorbell on newer chips has a significant performance improvement on pktgen. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.
