From 34d351f8ddf6dee24d739c4b00a4404e48089a04 Mon Sep 17 00:00:00 2001 From: Sebastian Sanchez Date: Thu, 9 Jun 2016 07:52:03 -0700 Subject: IB/hfi1: Send a pkey change event on driver pkey update Swapping a cable from a "Mgmt Allowed=No" switch port to a "Mgmt Allowed=Yes" switch port doesn't send a pkey change notification. Therefore, the link doesn't become active as the oib_utils layer uses an old pkey table cache. Fix by ensuring the pkey change notification is sent when the table is changed both explicitly by the FM and implicitly by the driver via a cable swap.
