From 0cece6c5832b7617c90adbdc14f231f2db23dca6 Mon Sep 17 00:00:00 2001 From: Raghu Vatsavayi Date: Tue, 14 Jun 2016 16:54:50 -0700 Subject: [PATCH] liquidio: Replace ifidx for FW commands This patch decoupled the firmware side ifidx and host side interface number. It also has some minor name change for linkinfo sturct field.
