From bb36071721699c531e19ea7c3e7eebd605e8b61d Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Mon, 16 May 2016 10:26:33 -0700 Subject: [PATCH] i40e: write HENA for VFs Now that VF RSS is configured by the PF driver, it needs to set the RSS Hash Enable registers by default. Without this, no packets will be hashed and they'll all end up on queue 0.
