From 9c349892ccc90c6de2baaa69cc78449f58082273 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Mon, 11 Apr 2016 11:35:27 +0200 Subject: [PATCH] brcmfmac: revise handling events in receive path Move event handling out of brcmf_netif_rx() avoiding the need to pass a flag. This flag is only ever true for USB hosts as other interface use separate brcmf_rx_event() function.
