From 56882e6cab432508c79b350d7842af3abac9c7d3 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 22 May 2015 11:33:12 +0200 Subject: [PATCH] iwlwifi: transport: track number of allocated queues As the transport will decide how many queues (and MSI-X vectors) to allocate, add a field to indicate that to the op-mode so it can size/allocate its own data structures appropriately.
