Start by moving the basic_rate_set field into it.
NOTE: in order to make the patches a bit smaller, start by

The mac address of the interface already exists in vif->addr.
Use it instead of wl->mac_addr.
It seems that due to some fw bug, we still need to set nvs->mac
to the actual mac addresss, otherwise the fw doesn't function
well (e.g. can't get dhcp address).
Thus, use wl->mac_addr for this purpose, and don't delete it yet.

The wl12xx FW supports HW channel switch. If we don't use it,
sometimes the firmware gets confused when recalibrating to the new
channel, causing RX problems. This commit adds HW channel switch
support by implementing the channell_switch op.

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.

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.

Change the commands and events according to the new fw api
(fw >= 6/7.3.0.0.75).
The main change is the replacement of JOIN/DISCONNECT commands,
with ROLE_START/ROLE_STOP commands.
The use of these commands should be preceded by the ROLE_ENABLE
command (allocating role resources), and followed by the
ROLE_DISABLE command (freeing role resources).

A recently added feature to the firmware enables the driver to retrieve
firmware logs via the host bus (SDIO or SPI).
There are two modes of operation:
1. On-demand: The FW collects its log in an internal ring buffer. This
buffer can later be read, for example, upon recovery.
2. Continuous: The FW pushes the FW logs as special packets in the RX
path.
Reading the internal ring buffer does not involve the FW. Thus, as long
as the HW is not in ELP, it should be possible to read the logs, even if
the FW crashes.
A sysfs binary file named "fwlog" was added to support this feature,
letting a monitor process read the FW messages. The log is transferred
from the FW only when available, so the reading process might block.

The probe-request template used in the hardware connection monitoring feature
thus far has been an empty one, without the SSID IE and without supported rate
IEs. This causes problems with some AP's.
Additionally, after connected scans, the template for connection maintenance
would remain to be the one last used for scanning - potentially incorrect.
Fix these by getting a pre-filled directed probe-request template for the
associated-to AP from mac80211.

Also try to make all commands safe for DMA transfers. I might have missed
