From 5ea614254332d8c8b2796835328fd6e623cca793 Mon Sep 17 00:00:00 2001 From: Jeff Guo Date: Tue, 19 May 2020 10:23:50 -0400 Subject: [PATCH] net/iavf: fix VF reset for RSS Since there are some default rss configure in kernel PF/VF but not DPDK IAVF, if these configurations be modified by VF and then VF reset, this default rss configurations can not be reset to default by IAVF. So need to add default rss set in IAVF hash initial process.
