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.

The keep alive template should have a max size of
sizeof(struct ieee80211_qos_hdr).
Additionally, Remove the redundant wl12xx_qos_null_data_template
struct.

The max template size was increased in the new fw.
However, we should use the max size only when needed, as it
consumes some of the chip's memory.
Thus, by default initialize the templates to the default size.
Initialize to the maximum size only when required.
Use WL1271_CMD_TEMPL_DFLT_SIZE instead of some of the
predefined structs, as some of them didn't account
for additional IEs that might be added to the template.
Delete structs defintions not used after these changes.

Split HW init sequence into AP/STA specific parts
The AP specific init sequence includes configuration of templates, rate
classes, power mode, etc. Also unmask AP specific events in the event mbox.
Separate the differences between AP and STA init into mode
specific functions called from wl1271_hw_init. The first is called after
radio configuration and the second after memory configuration.

Note that wl1271_write32() calls cpu_to_le32() by itself, so calling
wl1271_write32(addr, cpu_to_le32(val)) is in fact a bug on BE systems.

Inclusion of a WPS IE in probe requests caused a problem
in the driver due to the maximum size of the probe request
template and the max_scan_ie_len values at initialization.
Increased the size of probe request template
to the maximum size allowed by the firmware.
Struct wl12xx_probe_req_template, which was only used
for calculating the max size of the probe request template,
is no longer used and needed.
max_scan_ie_len is used for validating the size of
additional IEs in scan requests.
Initialized the max_scan_ie_len field to the maximum size
of the probe request template minus the ieee80211 header size.

The auto-arp feature of wl12xx allows the firmware to automatically
response to arp requests asking for its ip.
in order to use it, we configure the arp response template and
enable the corresponding bit in wl1271_acx_arp_filter (along with
passing its ip)

We were not handling endianess correctly. The wl1271 chip runs on
little-endian values. This patch makes sure that all the communication with
the wl1271 firmware is done in little-endian by using cpu_to_le* and
le*_to_cpu where appropriate.
Also, all the struct definitions for data exchanged with the firmware has
been changed to use __le16/32 types instead of u16/32.

wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded
devices, supporting both SDIO and SPI busses. Currently the driver
supports only SPI. Adding support 1253 (the 5 GHz version) should be
relatively easy. More information here:
