[dpdk-dev] [PATCH v5 23/29] i40e: use AQ rx control register read/write

Helin Zhang helin.zhang at intel.com
Tue Mar 8 09:14:31 CET 2016


RX control register read/write functions are added, as directly
read/write may fail when under stress small traffic. After the
adminq is ready, all rx control registers should be read/written
by dedicated functions.
