From 7742fce4c007141617dab9bcb90034b3c0fe2347 Mon Sep 17 00:00:00 2001
From: Franky Lin <franky.lin@broadcom.com>
Date: Thu, 26 Apr 2018 12:18:35 +0200
Subject: [PATCH] brcmfmac: reports boottime_ns while informing bss
Provides a timestamp in bss information so user space can see when the
bss info was updated. Since tsf is not available from the dongle events
boottime is reported instead.
