From c45bd78e07e9d4b5ffc29748b9b7d4127293597a Mon Sep 17 00:00:00 2001 From: Beilei Xing Date: Wed, 24 Feb 2021 10:09:00 +0800 Subject: [PATCH] net/i40evf: fix packet loss for X722 When Tx queue number is more than Rx queue number, and RSS is enabled, there'll be packet loss with X722. The root cause is the lookup table is not configured correctly, since it uses VF's queue pair number but not Rx queue number.
