From d4b4c68454871bc7e9adb7b54c57cc2606978fe9 Mon Sep 17 00:00:00 2001 From: Xiao Wang Date: Sun, 25 Sep 2016 17:00:10 +0800 Subject: [PATCH] net/ixgbe/base: add X550em_a FW ALEF support This patch adds X550em_a FW ALEF support. ALEF is the new unified FW. The driver uses the KRM_PMD_RX_FLEX_PORT/FLX_MASK_ST20 registers to configure the lane mode.
