From 09603eaa5ca91dd9a318d8722ff5de8feb1e36ab Mon Sep 17 00:00:00 2001 From: Akeem G Abodunrin Date: Thu, 1 Oct 2015 14:37:36 -0400 Subject: [PATCH] i40e: Fix VEB/VEPA bridge mode mismatch issue Fix i40e_is_vsi_uplink_mode_veb to check if bridge is actually in VEB mode before allowing LB in the add VSI routine, instead of unconditionally returning VEB bridge mode.
