From 6b75183ac4d08b34c476285f4650557aa3e38e19 Mon Sep 17 00:00:00 2001 From: Wenzhuo Lu Date: Mon, 20 Nov 2017 11:37:45 +0800 Subject: [PATCH] net/ixgbe: fix wrong PBA setting The datasheet says, if using MSI-X mode, the PBA support bit of the GPIE register must be set to 1. DPDK uses polling mode, we cannot hit this issue in the scenario DPDK PF + DPDK VF. If we use DPDK PF + kernel VF, as the kernel driver uses interrpt mode, VF may hit RX hang after running hours.
