From: Gregory Greenman <[email protected]>
Hi,
Here's the third set of patches intended for v6.2. It contains
EHT adjustments for iwlwifi. It contains only iwlwifi changes,
all the required mac80211/cfg80211 changes are already merged
upstream.
As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.
Please review.
Thanks,
Gregory.

2.35.3
From: Mordechay Goodstein <[email protected]>
Rate scale needs to be configured to what MCS it can use per BW and NSS,
this is done by parsing our capabilities of TX and peer's capabilities of
RX and setting the minimum for rate scale usage.
Also do some cleanup removing redundant enum defines not used by
FW/Driver.

In an EHT connection fill in the HE context command
with PPE Thresholds field from EHT Capabilities IE.
If PPE Thresholds field presents only in HE Capabilities IE,
take the thresholds from there.
If it's not present in both - set the Common Nominal Packet Padding
field from EHT Capabilities IE.

The bits are reserved on the opposite bands, so we shouldn't

We can't have it in AP mode unless for debug, since we don't have

Would it be more clear when it would say: "EHT capabilities *if*
