ath6kl: Support for TCP checksum offload to firmware

The change enables offloading TCP checksum calculation to firmware.
There are still some issues with the checksum offload so better to
disable it by default until the issues are resolved.

To enable TCP checksum offload for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx on
ethtool -K <interface> rx on

To disable TCP checksum offload, for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx off

In this way, caller is free to pass only the value of IP addr
to configure.

In addition to this,
* 'ips' variable data type in struct wmi_set_ip_cmd is changed
from __le32 to __be32 in order to match network byte order.
* ipv4_is_multicast() is used to validate multicast ip addr.
* New argument if_idx is added to supply correct vif index
to ath6kl_wmi_cmd_send().

This will be used in the next patch.

ath6kl: support for P2P mgmt operations on station interface

This patch enables support for doing P2P management operations like device
discovery on top of a station interface. After group formation, the station
interface will become a P2P GO/client interface as the case may be.

This feature requires modifications to a couple of existing WMI structures and
therefore new command ids and structures have been defined in order to be
compatible with older firmware versions and other chips. The exception here is
the wmi_connect_cmd. Adding a new field to the end of the structure will not
cause any issues with previous firmware versions since firmware only checks for
minimum length of the command. The other structures are of variable length,
hence it was not possible to add new fields to the end.

The new command ids have to be added to the end of enum wmi_cmd_id, so it has
updated to match the firmware.

The driver will support both the 'old' and the 'new' commands for a while by
checking the firmware capabilities.

ath6kl: implement scheduled scan

ath6kl firmware supports scheduled scan functionality with the wow ssid
filter. But the firmware does not send any events after scan results
so I had to add a timer which notifies about new scan results.

Sched scan needs firmware version 3.2.0.6 or later. If firmware doesn't
support sched scan the driver will not enable the feature.

ath6kl: add aborted parameter to ath6kl_cfg80211_scan_complete_event()

Currently it takes an error code as status, but what we really want to
tell is if the scan was aborted or not.

Also fix a bug where we were comparing firmware scan status values
with kernel error codes, which is obviously wrong. This meant
that ath6kl didn't detect when firmware informed about failed scans. I
doubt that this fix doesn't make any difference in practise but it
still needs to be fixed. This is fixed by adding an enum for the success
status code and checking for that.
