From: Rakesh Kudurumalla Date: Wed, 18 Jul 2018 15:05:02 +0000 (+0530) Subject: net/thunderx: support Rx VLAN offload X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d3bf25644ba51474b7e7c1fd4e6886bfc60d4a47;p=dpdk.git net/thunderx: support Rx VLAN offload This feature is used to offload stripping of VLAN header from received packets and update vlan_tci field in mbuf when DEV_RX_OFFLOAD_VLAN_STRIP & ETH_VLAN_STRIP_MASK flag is set.
