From 4022d789824391b1de503192a8ee8f8aac7f2e03 Mon Sep 17 00:00:00 2001 From: Viacheslav Ovsiienko Date: Wed, 21 Nov 2018 11:27:49 +0000 Subject: [PATCH] net/mlx5: fix TPID check for VLAN push action on E-Switch The VLAN push action on E-Switch supports only 802.1Q (0x8100) and 802.1AD (0x88A8) Tag Protocol ID (TPID) insertions. The parameter check for RTE_FLOW_ACTION_TYPE_OF_PUSH_VLAN action is added.
