This is the initial S1G patchset which adds support for: - defining the S1G 900MHz bands in a custom regulatory database - setting and receiving S1G beacons (sending short beacons will be supported in a future patch) - configuring S1G capabilities in Association Request (setting capabilities along with NL80211_CMD_SET_STATION will be added later). - scanning on S1G bands - handling S1G Association Response format - correctly encoding Listen Interval for S1G - associating in mac80211 - testing S1G in mac80211_hwsim Rate control is still TBD, this patchset simply lops off the rate control hooks for S1G so eg. missing sband->bitrates and S1G Basic Rate set can't do too much damage. Note the mac80211_hwsim S1G support introduces a regression in a few hostap hwsim tests. This is because when processing the reported bands, hostap assumes freq < 4000 is 11b, and the actual 11b/g band is overwritten by the S1G band info. Though it does count as a userspace regression, I'm not sure there is much to do about it besides apply a small patch to hostapd which treats freq < 2000 as an unknown band. After the hostap workaround (https://lists.infradead.org/pipermail/hostap/2020-August/038748.html), these patches continue to pass the hwsim tests as well as HEAD.
