On some RFs we want to advertise vendor specific capabilities to
indicate support for improved beamforming rates and/or on 160 MHz,
some APs where Intel has collaborated with the vendor will use it
to improve behaviour. Add these elements where relevant, i.e. for
HR and GF RFs.

The (default) HE capabilities for our devices weren't handled
correctly, adjust them to match the correct capabilities of

Since the device regulatory will not allow 160 MHz on 5 GHz,
don't advertise this capability by default; do it only if an

When version 2 of the regulatory capability flags API was implemented,
the flag to disable 11ax was defined as bit 13, but this was later
changed and the bit remained as bit 10, like in version 1. This was
never changed in the driver, so we were checking for the wrong bit in
newer devices. Fix it.

This is an old parameter that was used supposed to be used only when
LAR was still under development. It should not be used anymore, but,
since it's available, end-users have been mangling with it

is supported the driver and the firmware do not expect it to be

In order to be able to select the cfg depending on the HW revision or
on the RF ID, we need to set up the trans before selecting the cfg.
To do so, move the elements from cfg that are needed by
iwl_trans_alloc() to a separate struct at the top of the cfg, so it
can be used by other cfg types as well, before selecting the rest of
the configuration.

One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

With NICs that don't read the NVM directly and instead rely on getting
the relevant data from the firmware, the number of reserved MAC
addresses was not added to the API. This caused the driver to assume
there is only one address which results in all interfaces getting the
same address. Update the API to fix this.
While at it, fix-up the comments with firmware api names to actually
match what we have in the firmware.

code a lot at the cost of having bigger memory usage. However in most
cases we have only few reg_rule's and when we do have many like in
iwlwifi we do not save memory as it allocates a separate wmm_rule for
each channel anyway.

The current channel flags printing is very strange and messy,
in LAR we sometimes print the channel number and sometimes the
frequency, in both we print a calculated value (whether ad-hoc
is supported or not) etc.
Unify all this to
* print the channel number, not the frequency
* remove the band print (2.4/5.2 GHz, it's obvious)
* remove the calculated Ad-Hoc print
Doing all of this also gets the length of the string to a max
of 101 characters, which is below the max of 110 for tracing,
and thus avoids the warning that came up on certain channels
with certain flag combinations.

When we create a regulatory domain out of an MCC
notification, we need to make sure that all the channels
in the rule have the exact same properties.
The current code mixes channel 36 and 40 although 36 can be
a control channel with HT40+ (36, 40) whereas 40 can't be
a control channel with HT40+ since (40, 44) is invalid.
Because of that, cfg80211 would allow to connect in 40MHz
to APs that are configured to channel 40 HT40+ and that made
our firmware assert.
Fix this by checking the bandwidth flags before taking the
decision if the rule should be split.
