net/wireless/brcm80211/brcmfmac: Make return type and name reflect actual semantics

2014-06-25T19:32:47+00:00

Applying ++ to a bool is equivalent to setting it true, regardless of its initial value (bools are not uint1_t). Hence the function wl_get_vif_state_all can only ever return true/false. The only in-tree caller uses its return value as a boolean. So update its return type, and since the list traversal and bit testing have no side effects, just return true immediately. Its return value tells if any vif is in the specified state, so also rename it to brcmf_get_vif_state_any. Reviewed-by: Arend van Spriel Signed-off-by: Rasmus Villemoes Signed-off-by: John W.

brcmfmac: remove mode field from brcmf_cfg80211_vif structure

2014-03-17T17:44:14+00:00

The nl80211 iftype was converted to a mode value and stored in brcmf_cfg80211_vif structure. The value was used only within brcmfmac driver to decide execution of conditional code. Better use wireless_dev::iftype for that as the wdev is contained in the brcmf_cfg80211_vif structure.

brcmfmac: Make firmeware roaming a module param.

2014-02-28T19:33:17+00:00

Internal firmware roaming is enabled by default. This patch makes it possible to disable internal firmware roaming by specifying roamoff=1 as module param.

cfg80211: make connect ie param const

2014-02-04T20:48:10+00:00

This required liberally sprinkling 'const' over brcmfmac and mwifiex but seems like a useful thing to do since the pointer can't really be written. Signed-off-by: Johannes Berg

brcmfmac: use custom destructor callback for all netdevice interfaces

2014-01-06T20:48:06+00:00

The destructor for net devices was set to free_netdev() to get rid of it and the private data. The private data refers to a brcmf_if instance, but indirectly it also refers to brcmf_cfg80211_vif which holds the wdev. This is freed as well by using a new custom destructor called brcmf_cfg80211_free_netdev().

brcmfmac: move wiphy_unregister() call to brcmf_cfg80211_detach()

2014-01-06T20:48:04+00:00

The wiphy_unregister() call was done in brcmf_free_vif() when the last interface was being removed. This is not the obvious place to do that. This patch moves it to the brcmf_cfg80211_detach(). This removes the need to keep count of interfaces. Reviewed-by: Hante Meuleman Reviewed-by: Pieter-Paul Giesberts Signed-off-by: Arend van Spriel Signed-off-by: John W. Linville

2013-05-28T17:43:09+00:00

Pass the struct brcmf_cfg80211_info instance instead of obtaining through vif itself using vif->wdev. This is needed as the netdev associated with this vif is already unregistered. Reviewed-by: Hante Meuleman Signed-off-by: Arend van Spriel Signed-off-by: John W. Linville

brcmfmac: support critical protocol API for DHCP

2013-04-23T18:16:52+00:00

Adds support for the critical protocol API provided by nl80211 which gives Wifi traffic priority over a Bluetooth (e)SCO connection and disables scanning during DCHP negotiation.

brcmfmac: obtain iftype for firmware-signal descriptor lookup

The function brcmf_fws_find_mac_desc() determines the descriptor associated with a sk_buff for firmware-signalling. It needs the interface type to do that. For this a helper function is added in wl_cfg80211.c. Reviewed-by: Hante Meuleman Reviewed-by: Pieter-Paul Giesberts Reviewed-by: Piotr Haber Signed-off-by: Arend van Spriel Signed-off-by: John W.
