wifi: iwlwifi: handle eSR transitions

There several transitions to handle in eSR mode:
* SMPS should be disabled when in eSR mode
* indicate to the fw whether the new added link should use the

* RLC is offloaded when in eSR mode; adjust RLC command accordingly

wifi: iwlwifi: fix max number of fw active links

The max active links that are supported by the FW is hard coded.
This is wrong since this value is HW-dependent. Fix this by
determining according to the actual HW.

Also remove a redundant check that the number of active links
doesn't exceeds the maximum.

wifi: mac80211: Remove "Missing iftype sband data/EHT cap" spam

In mesh mode, ieee80211_chandef_he_6ghz_oper() is called by
mesh_matches_local() for every received mesh beacon.

On a 6 GHz mesh of a HE-only phy, this spams that the hardware does not
have EHT capabilities, even if the received mesh beacon does not have an

wifi: iwlwifi: dbg-tlv: clear FW debug memory on init

When we restart the firmware, we shouldn't keep old debug data
around. Since the "allocate" function might not reallocate the
memory blocks (they're only freed when we unbind from the device),
clear the memory to have a clean slate for debug data.

This is a bit more complex since we normally don't enter into
the allocation function, but duplicating the logic didn't seem
enticing either, so rework the allocation a bit to always go

wifi: iwlwifi: dbg-tlv: fix DRAM data init

Given the existing code in iwl_dbg_tlv_update_drams(), the
following can happen and cause firmware asserts, and even
the device to become unusable:

 * We set the magic so the firmware will use the data;
 * we try to fill multiple allocation IDs, with at least
   one successful, but - crucially - one failing and thus
   not touching the data;
 * we don't clear the data since there was one success.

This doesn't seem like much of a problem just yet, however,
what happens now is that the allocation ID(s) that failed
are not initialized.

There are two additional things to know:
 * we never free these allocations across FW restart or
   interface down/up etc., in fact we never free them until
   the driver is unbound from the device (e.g. unloaded)
 * the firmware uses the DRAM info structure for real debug
   data when it has used it completely

Given that, and the fact that we never initialize the data
on restart, we can be unlucky and end up with an allocation
that looks for the most part valid (valid ID, valid number
of buffers, etc.) but has bad sizes - causing the firmware
to throw an assert we can never recover from.

Fixing the code to have the entire buffers cleared (which
we should do so old debug data isn't sticking around) is a
bit more complex, so as a first step make the actual code
that fills the information more robust by clearing the
structure first, and filling the magic values only if it
actually succeeded for one, rather than doing it the other
way around.

====================
tools: ynl-gen: code gen improvements before ethtool

I was going to post ethtool but I couldn't stand the ugliness
of the if conditions which were previously generated.
So I cleaned that up and improved a number of other things
ethtool will benefit from.

tools: ynl-gen: support / skip pads on the way to kernel

Kernel does not have padding requirements for 64b attrs.
We can ignore pad attrs.

The op_name argument is barely used and identical to op.name
in all cases.

tools: ynl-gen: support code gen for events

Netlink specs support both events and notifications (former can
define their own message contents). Plug in missing code to
generate types, parsers and include events into notification
tables.

tools: ynl-gen: sanitize notification tracking

Don't modify the raw dicts (as loaded from YAML) to pretend
that the notify attributes also exist on the ops. This makes
the code easier to follow.

tools: ynl-gen: stop generating common notification handlers

Common notification handler was supposed to be a way for the user
to parse the notifications from a socket synchronously.
I don't think we'll end up using it, ynl_ntf_check() works for
all known use cases.

tools: ynl: regen: regenerate the if ladders

Renegate the code to combine } and else and use tmp variable
to store type.

tools: ynl-gen: get attr type outside of if()

Reading attr type with mnl_attr_get_type() for each condition
leads to most conditions being longer than 80 chars.
Avoid this by reading the type to a variable on the stack.

tools: ynl-gen: combine else with closing bracket

Code gen currently prints:

  }
  else if (...

This is really ugly. Fix it by delaying printing of closing
brackets in anticipation of else coming along.

which we don't need.
