From 25be862370031056989ee76e3c48c3ac8ff67fd4 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 5 Apr 2016 14:09:00 -0400 Subject: [PATCH] bnxt_en: Set async event bits when registering with the firmware. Currently, the driver only sets bit 0 of the async_event_fwd fields. To be compatible with the latest spec, we need to set the appropriate event bits handled by the driver. We should be handling link change and PF driver unload events, so these 2 bits should be set. Signed-off-by: Michael Chan Signed-off-by: David S.
