From c7aeb4d1b9bfdb4e07da1c77cb095f02e912a83f Mon Sep 17 00:00:00 2001 From: Akeem G Abodunrin Date: Wed, 26 Jun 2019 02:20:18 -0700 Subject: [PATCH] ice: Disable VFs until reset is completed This patch adds code to clear VFs enable status until reset is completed, and Tx/Rx rings are setup. Without this patch, the code flow request Tx queues to be disabled after reset, especially PFR - where VF VSI Tx rings have already been wiped off in the NVM and result to adminq error based on the call to disable Tx LAN queue in ice_reset_all_vfs function call.
