   4 Subject: [PATCH 093/703] brcm: adds support for BCM43341 wifi
   5
   6 brcmfmac: Disable power management
   7
   8 Disable wireless power saving in the brcmfmac WLAN driver. This is a
   9 temporary measure until the connectivity loss resulting from power
  10 saving is resolved.

  14 brcmfmac: Use original country code as a fallback

  18     brcmfmac: Configure country code using device specific settings
  19
  20 prevents region codes from working on devices that lack a region code
  21 translation table. In the event of an absent table, preserve the old
  22 behaviour of using the provided code as-is.

  32 brcmfmac: do not use internal roaming engine by default
  33
  34 Some evidence of curing disconnects with this disabled, so make it a default.
  35 Can be overridden with module parameter roamoff=0
  36 See: http://projectable.me/optimize-my-pi-wi-fi/
