I have a BCM4350: 3a:00.0 Network controller: Broadcom Corporation
Device 43a3 (rev 08). It's a Dell M.2 wireless card. This card is
supported in wireless-testing but not in 4.3.
On resume, my wireless doesn't come up. When I manually turn on the
link (by telling NetworkManager to turn it on), it works. After
suspend/resume, the same thing happens: it's down on resume.
I'm running:

I assume that's what's causing the problem.
