From 7b8ff0f9cc531ce4367827e335c8bf0488d245f8 Mon Sep 17 00:00:00 2001 From: Piotr Raczynski Date: Fri, 26 Oct 2018 11:44:33 -0700 Subject: [PATCH] ice: Increase Rx queue disable timeout With much traffic coming into the port, Rx queue disable procedure can take more time until all pending queue requests on PCIe finish. Reuse ICE_Q_WAIT_MAX_RETRY macro and increase the delay itself.
