From c8a1071df934934a63e80b0bbd068b37043715e6 Mon Sep 17 00:00:00 2001 From: Lukasz Czapnik Date: Thu, 27 Feb 2020 10:15:00 -0800 Subject: [PATCH] ice: Increase mailbox receive queue length to maximum Currently the PF's mailbox receive queue is only 512 entries. This fine, but considering that all VF's mailbox send queues funnel into the PF's single mailbox receive queue, let's increase it to the maximum size. This will help prevent any possible bottleneck/slowdown occurring from the PF's mailbox receive queue being full.
