From: Wenzhuo Lu Date: Thu, 10 Mar 2016 02:42:13 +0000 (+0800) Subject: ixgbe: offload VxLAN and NVGRE Rx checksum on X550 X-Git-Tag: spdx-start~7460 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d909af8f72ca3f8ab4fe1942abfb4f53e15ff8bc;p=dpdk.git ixgbe: offload VxLAN and NVGRE Rx checksum on X550 X550 will do VxLAN & NVGRE RX checksum off-load automatically. This patch exposes the result of the checksum off-load.
