From a333f7f3fd327d736a23c52aafcfe17c75f2610c Mon Sep 17 00:00:00 2001 From: "Mintz, Yuval" Date: Thu, 1 Jun 2017 15:29:05 +0300 Subject: [PATCH] qed: Add aux. function translating sb_id -> igu_sb_id An additional step for relaxing the IGU order assumption, we now add an auxiliary function that can be used for finding the HW status block that's associated with a given MSI-x vector.
