Eliad Peller 5ec8a448e0 wl12xx: consider encryption and QoS in auto arp template
When configuring the arp response template,
and encryption is enabled, we should add some
space and set the protected flag bit in the fc.

In order to track the encryption type, set
wlvif->encryption_type when setting an encryption key,
and reconfigure the arp response. Clear this field on
wl1271_join, as keys have to be re-configured
anyway after a join command.

Similarly, track whether QoS is configured.

Eyal Shapira f1d63a5963 wl12xx: add support for HW dynamic PS
FW now supports dynamic PS so we don't need to use mac80211 support.
FW will go to PSM after a specified timeout with no Rx/Tx traffic.
- Changed FW API to include new PS mode (AUTO_MODE) and including timeout parameter
- The default PS mode would be dynamic PS
- Default timeout is 100ms (same as it used to be in mac80211)
- Avoid using mac80211 APIs to disable/enable dynamic PS as we're not
using mac80211 PS control anymore.
- COEX is handled by the FW while in dynamic PS so removed
handling of SOFT_GEMINI

Eliad Peller cdaac62811 wl12xx: fw api change - add role_id to set_template
The set_template commands now takes the role_id as
parameter.

Usually, we'll use the vif's main role_id.
However, sometimes we'll want to use
wlvif->dev_role_id instead of wlvif->role_id,
so pass the wanted role_id as param.

Update WL127X_FW_NAME/WL128X_FW_NAME.

(This commit starts a series of fw update patches,
and changes the start() callback to return an error
in order to prevent the use of the driver during the
transition. This change will be reverted in the
last patch of series)

Device role is always started along with ROC.
Couple them together by introducing new wl12xx_start_dev

ROCed on a different one.

Eliad Peller 251c177f88 wl12xx: replace dummy_join with ROC/CROC commands
The ROC command asks the fw stay on the channel of the given
hlid. it currently has 2 primary functions:

1. Allow tx/rx from the device role.

In order to tx/rx packets while the stations is not associated
(e.g. auth req/resp), the device role has to be used, along
with ROC on its link.

Keep the logic similiar to the one used in dummy_join. However,
since we can't scan while we ROC, we add CROC before starting
a scan, and ROC again (if needed) on scan complete.

2. Keeping the antenna for a specific link.

We ROC until the connection was completed (after EAPOLs exchange)
in order to prevent BT coex operations from taking the antenna
and failing the connection (after this stage, psm can be used).

During association, we ROC on the station role, and then CROC
the device role, thus assuring being ROC during all the connection
process.

Delete the WL1271_FLAG_JOINED flag, and use a roc bitmap
to indicate what roles are currently ROCed.

Add wl12xx_roc/croc functions in order to wrap the roc/croc
commands while taking care of the roc bitmap.

The current ROC/CROC state-machine is a bit complicated. In
the future we'll probably want to use wpa_supplicant to control
the ROC during connection.
