From 973371da4d66b96736143bd3f2b2ff2331faae8f Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Mon, 27 Apr 2015 14:57:09 -0400 Subject: [PATCH] i40evf: Allow for an abundance of vectors The driver currently only maps TX and RX queues to a single MSI-X vector per queue pair if there are exactly enough vectors for this. Unfortunately, if we have too many vectors it will fail and allocate queues to vectors in a suboptimal manner. Change the condition check to allow for excess vectors. In this case, the extras just won't be used.
