Subject: [PATCH] brcm: adds support for BCM43341 wifi
brcmfmac: Disable power management
Disable wireless power saving in the brcmfmac WLAN driver. This is a
temporary measure until the connectivity loss resulting from power
saving is resolved.
Signed-off-by: Phil Elwell <phil@raspberrypi.org>
brcmfmac: Use original country code as a fallback
Commit 73345fd212980d2e28a5c6d83801c903bd773680:
brcmfmac: Configure country code using device specific settings
prevents region codes from working on devices that lack a region code
translation table. In the event of an absent table, preserve the old
behaviour of using the provided code as-is.
Signed-off-by: Phil Elwell <phil@raspberrypi.org>
brcmfmac: Plug memory leak in brcmf_fill_bss_param
See: https://github.com/raspberrypi/linux/issues/1471
Signed-off-by: Phil Elwell <phil@raspberrypi.org>
brcmfmac: do not use internal roaming engine by default
Some evidence of curing disconnects with this disabled, so make it a default.
Can be overridden with module parameter roamoff=0
See: http://projectable.me/optimize-my-pi-wi-fi/
brcmfmac: Change stop_ap sequence
Patch from Broadcom/Cypress to resolve a customer error
