Subject: [dpdk-dev] [PATCH] net/i40e: fix ethertype filter issue for new FW
Date: Tue, 18 Jul 2017 11:07:07 +0800 [thread overview]
Message-ID: <1500347227-67664-1-git-send-email-beilei.xing@intel.com> (raw)
SW workaround for GL_SWR_PRI_JOIN_MAP is added for X710
performance before. As new FW version 6.0 supports ADQ,
value for GL_SWR_PRI_JOIN_MAP should be changed, otherwise
ehtertype filter will be impacted.
Fixes: 973273c7a4b7 ("i40e: workaround for X710 performance")
