QLINK_CMD_PHY_PARAMS_GET command does not need to be separate,
it can be included into GET_MAC_INFO command. Merge these two
commands adding all the missing wiphy data.

To support any number of capabilities bits in the future,
replace u32 capabilities bitmask by array. Pass
capabilities from firmware using TLV element.

Use MAJOR.MINOR format for QLink firmware protocol. MAJOR part is
incremented when backward compatibility is broken. Normally this
part should not be incremented unless there is a good reason for
that. MINOR part is incremented each time when new features are
added to qlink.h, e.g. new TLVs, events, commands. These changes
should not break backward compatibility. For instance, older
firmware versions may not be able to parse new flags or send new
types of events, but this does not impact normal system operations.

As part of initialization sequence, driver requests protocol version
from firmware and refuses to start in case there is a mismatch in MAJOR
part of the version.

Bridging qtnfmac interfaces is possible only if the following two
conditions are fulfilled:
- firmware advertises proper support with QLINK_HW_CAPAB_HW_BRIDGE
- kernel is built with CONFIG_NET_SWITCHDEV support

Otherwise adding qtnfmac wireless interfaces into the same bridge
should not be allowed since packets flooded by kernel may break
internal forwarding rules between interfaces.

This patch disables adding qtnfmac wireless interfaces into the
same bridge if no support is provided either by card or by kernel.

Firmware may support DFS offload. However the final decision on whether
to use it or not should be up to the user. So even if firmware supports
DFS offload, it should be enabled only if user explicitly requests it.
For this purpose introduce kernel param dfs_offload which is disabled
by default.

Currently this parameter is global, it is not specific to mac.
So this function does not need any input parameters.

This allows incrementing the correct timeout statistic without any mess.
Down the road, devices can learn to reset just the specific queue.

If firmware reports that it supports hardware switch capabilities,
driver needs to track and notify device whenever broadcast domain
of a particular network device changes (ie. whenever it's upper
master device changes).

Firmware needs a unique ID to tell broadcast domains from each other
which is an opaque number otherwise. For that purpose we can use
netspace:ifidx pair to uniquely identify each broadcast domain:
 - if netdev is not part of a bridge, then use it's own ifidx
   as a broadcast domain ID
 - if netdev is part of a bridge, then use bridge netdev ifidx
   as broadcast domain ID

Firmware makes sure that packets are only forwarded between
interfaces marked with the same broadcast domain ID.

Driver uses statically allocated wdev structures for each virtual

its uses. As a result, various bugs appear when userspace tools
like hostapd were not gracefully stopped.

In particular, this commit fixes the following issue:
- start hostapd with more than 2 mBSS
- kill hostapd using SIGKILL
- start again hostapd with more than 2 mBSS
However only two mBSS entities will be started: primary
and the last BSS listed in hostapd config.

Update existing code handling configuration of supported interface
combinations. Current implementation is not complete since it does
not report multiple interface combinations which are incompatible
with each other. Instead current implementation packs all the
supported combinations into single entry.

In fact currently qsr10g wireless card supports the following
two distinct interface combinations:

1. STA/repeater: 1 STA and/or 1 AP
   {
     { .max = 1, .types = NL80211_IFTYPE_AP},
     { .max = 1, .types = NL80211_IFTYPE_STA},
   }

2. AP/mBSS
   {
     { .max = 8, .types = NL80211_IFTYPE_AP},
   }

The list of supported configuration is reported by firmware during
wireless card bring-up. Communication protocol between firmware
and host has been updated accordingly in order to accommodate passing
multiple interface combination entries.

This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.

Casting from unsigned long:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, ptr);

and forced object casts:

    void my_callback(struct something *ptr)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);

become:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

Direct function assignments:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    ptr->my_timer.function = my_callback;

have a temporary cast added, along with converting the args:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;

And finally, callbacks without a data assignment:

    void my_callback(unsigned long data)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, 0);

have their argument renamed to verify they're unused during conversion:

    void my_callback(struct timer_list *unused)
    {
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

The conversion is done with the following Coccinelle script:

spatch --very-quiet --all-includes --include-headers \
	-I ./arch/x86/include -I ./arch/x86/include/generated \
	-I ./include -I ./arch/x86/include/uapi \

HT/VHT capabilities must be reported per each band supported by a radio,
not for all bands on a radio. Furthermore, driver better not assume
any capabilities and just use whetever is reported by device itself.

To support this, convert "get channels" command into "get band info"
command. Difference is that it may also carry HT/VHT capabilities along
with channels information.

While at it, also add "num_bitrates" field to "get band info" command,
for future use.

Current recovery approach is to wake s/w Tx queues for skb->dev netdevice.
However this approach doesn't cover the case when h/w queue is full of
packets from a single wireless interface. Suppose xmit attempt from the
second wireless interface fails due to failed reclaim. Then the second
interface will not have a chance to recover even if subsequent reclaims
succeed. Possible solution is to attempt to wake all the s/w queues
belonging to driver interfaces.

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

Userspace tools may hang on scan in the case when scan completion event
is not returned by firmware. This patch implements the scan timeout
to avoid such situation.

On startup driver obtains regulatory rules from firmware and
enables them during wiphy registration. Later on regulatory
domain change can be requested by host. In this case firmware
is notified about the upcoming changes. If the change is valid,
then firmware updates hardware channel configuration and host
driver receives updated channel info for each band.
