@ldc:
- I did observe multiple times now, that killing the wpa_supplicant + reconnecting to the wifi solved the no traffic issue. 
- I can reproduce it quite good in the company  by changing the floor (and thus, getting a different access point with the same ssid)

- Does that workaround work for your "no traffic" situations, too? With
having looked into the code, I bet the crypto WPA stuff is done with the
wrong (old, before roaming) BSSID in the keys or challenge response or
whatever.

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.
