2013-06-13brcmfmac: free primary net_device when brcmf_bus_start() failsArend van Spriel
When initialization within brcmf_bus_start() fails on steps before the brcmf_net_attach() the net_device for the primary interface needs to be freed. This patch resolves a panic during kernel boot as reported by Stephen Warren. ref.: http://mid.gmane.org/51AD1F22.2080004@wwwdotorg.org Tested-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Hante Meuleman <meuleman@broadcom.com> Reviewed-by: Pieter-Paul Giesberts <pieterpg@broadcom.com> Signed-off-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: John W.

2013-06-12brcmsmac: disable power-save related functionsArend van Spriel
This patch fixes a regression introduced by: commit 6da3b6c48d79da96a36c2632053cf4f53bf48fb2 Author: Hauke Mehrtens <hauke@hauke-m.de> Date: Sun Mar 24 01:45:52 2013 +0100 brcmsmac: remove brcms_bss_cfg->associated The regression behaviour was described on mailing list. http://mid.gmane.org/5197DC4F.7030503@broadcom.com: "On laptop I installed kernel with brcmsmac compiled as module. It comes up and associates during boot, but after logging in there is no connectivity. Triggering reassoc gives connectivity for some time, but after a while (1-2 min) it stops." Before the mentioned commit the return value of the function brcms_c_ps_allowed() was always false, which is desired behaviour as power-save is not supported at the moment. Therefor, the function is changed to just return false instead of simply reverting the mentioned commit.

2013-04-08brcmfmac: only use ifidx from BDC header in brcmf_rx_frames()Arend van Spriel
In brcmf_rx_frames() the call to brcmf_fweh_process_skb() could change the ifidx using information in the event data. This is only different to the BDC ifidx for IF ADD event. However, the creation of the new interface is deferred to event worker so it does not exist. After brcmf_fweh_process_skb() it is only used to set statistics.

2013-04-08brcmfmac: obtain wdev using vif object in action frame rxArend van Spriel
The function brcmf_p2p_notify_action_frame_rx() the wireless_dev is needed to pass the action frame to cfg80211. The wireless_dev is held in brcmf_cfg80211_vif object. Use that instead of the ieee80211_ptr in net_device as P2P_DEVICE interface does not have a net_device associated with it.
