Subject: [PATCH v5 0/2] Add support for new channels on 60GHz band

The following set of patches add support for new channels on
60GHz band and EDMG channels:
Changelog:
V5:
- Addressed to comments from the community
- Added enum for bw_config
- Updated nla_policy to NLA_POLICY_RANGE()
V4:
- Addressed to comments from the community
- Updated comments and variable name
V3:
- Addressed to comments from the community
- Added 60G check for verifying some EDMG cases are relevant
- Used the ieee80211_sta_edmg_cap struct as the edmg channel configuration
- Updated nla_policy to NLA_POLICY_RANGE()
V2
- Addressed to comments from the community
- Align to latest Spec release

Subject: [PATCH v5 1/2] nl80211: Add support for EDMG channels

802.11ay specification defines Enhanced Directional Multi-Gigabit
(EDMG) STA and AP which allow channel bonding of 2 channels and more.
Introduce NL80211_ATTR_WIPHY_EDMG_CHANNELS,
NL80211_ATTR_WIPHY_EDMG_BW_CONFIG, NL80211_BAND_ATTR_EDMG_CHANNELS,
NL80211_BAND_ATTR_EDMG_BW_CONFIG and RATE_INFO_FLAGS_EDMG
that needed for enabling and configuring EDMG support.
Driver is expected to report its EDMG capabilities: whether EDMG
is supported and the supported EDMG channels.
Bitrate calculation is enhanced to take into account EDMG support
according to the 802.11ay specification.
The kernel uses NL80211_BAND_ATTR_EDMG_CHANNELS and
NL80211_BAND_ATTR_EDMG_BW_CONFIG attributes in order to publish
the EDMG capabilities to the userspace.
NL80211_BAND_ATTR_EDMG_CHANNELS is a bitmap field that indicates
the 2.16 GHz channel(s) that are allowed to be used.
If NL80211_BAND_ATTR_EDMG_CHANNELS is not set then EDMG not
supported. NL80211_BAND_ATTR_EDMG_BW_CONFIG represent the allowed
channel bandwidth configurations.
NL80211_ATTR_WIPHY_EDMG_CHANNELS and NL80211_ATTR_WIPHY_EDMG_BW_CONFIG
will be used by the userspace for AP configuration and connect command.

Subject: [PATCH v5 2/2] wil6210: Add EDMG channel support

Add support for Enhanced Directional Multi-Gigabit (EDMG) channels 9-11.
wil6210 reports it's EDMG capabilities (that are also based on FW
capability) to cfg80211 by filling
wiphy->bands[NL80211_BAND_60GHZ]->edmg_cap.
wil6210 handles edmg.channels and edmg.bw_config requested in connect
and start_ap operations.

Hi Alexei,

I'm not exactly sure why, but this breaks practically all connectivity
on 2.4 and 5 GHz channels (at least in hwsim tests).

Please check and resubmit.

It'd also be good to reformat the commit log a bit, maybe adding
paragraphs, it's a bit of a "wall of text".

Thanks,
johannes

Sorry for this issue, we have run hwsim test through wpa_supplicant and
catch small issue that caused the tests to fail - fix raised.
Can you please share with us how you run the hwsim, you also used the
wpa_supplicant unit tests or some other tool?

Yes, I keep saying "hwsim tests" when really I mean the hostap hwsim-
based tests...
