Additionally, if the skb is a dummy packet, re-enqueue

We need to set the extended radio parameters for wl127x only.
Currently, we were only calling this command with wl127x STA mode, but
we should also do it for AP mode.

Move the call to the extended radio paramaters to the common hw_init
and use a single if for the chip type to do everything at once.

We should not get an hlid value bigger than WL12XX_MAX_LINKS from
wl1271_rx_handle_data().  We have a WARN_ON in case it happens.  But
despite the warning, we would still go ahead and write the hlid bit
into active_hlids (a stack variable).  This would cause us to
overwrite other data in the stack.

To avoid this problem, we now skip the write when issuing the warning,
so at least we don't corrupt data.

This patch is an initial implementation for the NFC Logical Link Control
protocol. It's also known as NFC peer to peer mode.
This is a basic implementation as it lacks SDP (services Discovery
Protocol), frames aggregation support, and frame rejecion parsing.
Follow up patches will implement those missing features.
This code has been tested against a Nexus S phone implementing LLCP 1.0.

cfg_workqueue was added to notify cfg80211 that scan, connect
or disconnect is done by calling respective completion handlers.
We can avoid use of this workqueue by calling those handlers
from other places.
1) Call connect, disconnect completion handlers in their callback
   functions.
   ex. Call cfg80211_connect_result() in mwifiex_cfg80211_connect()
2) Call scan completion handler after parsing response of last scan
   command in a queue.

After removing the workqueue, variables (assoc_request etc.) and
checks used for mutual exclusion become redundant. Those are also
removed in this patch.

it to free command queue. While doing that it deletes the
