From 8bd8bae9c389c1664d095424f5ad1549614cd29c Mon Sep 17 00:00:00 2001 From: Shaopeng He Date: Fri, 5 Feb 2016 12:57:49 +0800 Subject: [PATCH] fm10k: make default VID available in initialization When the PF establishes a connection with Switch Manager(SM), it receives a logical port range from SM, and registers certain logical ports from that range. Then a default VID will be sent back from the SM. This whole transaction - finishing with the default VID being set - needs to be completed before dev_init returns. If not, the interrupt setting will subsequently be changed in dev_start according to the RX queue number, and that can cause this transaction to fail.
