From: Beilei Xing Date: Tue, 4 Jul 2017 08:26:16 +0000 (+0800) Subject: net/i40e: support VLAN stripping for VF X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5f0b95d59a98c77deb5171d2c6f1fdf794f32c01;p=dpdk.git net/i40e: support VLAN stripping for VF VLAN stripping configuration is supported only for DPDK PF previously. Since kernel PF supports VLAN stripping now, this patch adds VLAN stripping support for both DPDK PF and kernel PF.
