Hi Andreas,

Thanks for the assistance... What kernel-version and model of the wifi-
card are you using? Does it behave the same on both 2.4 and 5 Ghz?

For suspend/resume the pm-script seems to make it more stable atleast...
When/if getting the "no traffic bug" it's enough to unload/load the
module. It *may* take a few tries but the link comes back at least.. But
i think that since you suspend (and unload the driver) it should perform
better than before at least....

During a full day of normal usage i have lost my link once, so it's an
improvement... unload / wait a few sec / load worked for me straight off
today.. Yesterday i had to reload it a few times, but then i did not
wait at all between unload/load, but it succeeded to come back anyway.

Main part of the patch is for 4.x support, but there is a couple of
things to prevent complete system-crashes. (Think it was in 3.18 or 3.19
that behavior started.)

I'm currently just trying to figure out a way to trigger the issue here,
in a reproducible way, to allow for some easier debugging.

Title:
  bcmwl-kernel-source fixes [Patch]

Status in bcmwl package in Ubuntu:
  Confirmed

Bug description:
  
  The broadcom-wl driver have a few issues that have not been corrected in the ubuntu package.
  Supplied with this bugreport is a monolithic patch that addresses some of those.

  Summary/testing of patch:
  - 2 days of local testing with associate/disassociate/scan between 2 access-points. (same model and running same openwrt version, so might not be a good test).
  - Suspend/resume seems to work (no extensive testing there yet).
  - Testing been done on a MBP 11,3 with a BCM4360 card running Ubuntu 15.04 with kernel 4.1.3 (vanilla)
  - Only 4.x changes are new, rest have been in use by several projects (ubuntu/gentoo/archlinux etc) for some time.

  
  Feel free to split it up into several patches.... This have been a locally maintained repo that have used several different sources and that's the reason for the monolithic patch.

  One issue that is left is the:
          if (WARN_ON(!bss))
                  return;
  in net/wireless/sme.c but this does not seem to cause issues.
