From 75d2b253026b8b1cb625f6ccdb9d54cdecae7935 Mon Sep 17 00:00:00 2001 From: Anirudh Venkataramanan Date: Wed, 19 Sep 2018 17:42:54 -0700 Subject: ice: Add support to detect SR-IOV capability and mailbox queues Mailbox queue is a type of control queue that's used for communication between PF and VF. This patch adds code to initialize, configure and use mailbox queues. This patch also adds support to detect and parse SR-IOV capabilities returned by the hardware.
