From: Sven Eckelmann <seckelmann@datto.com>
The capabilities for the HE mesh are generated from the capabilities
reported by the fw. But the firmware only reports the overall capabilities
and not the one which are specific for mesh. Some of them (TWT, MU UL/DL,
TB PPDU, ...) require an infrastructure setup with a main STA (AP)
controlling the operations. This is not the case for mesh and thus these
capabilities are removed from the list of capabilities.

---
* v7
- remove SU patch since the problems couldn't be reproduced (at the moment)
with firmware WLAN.HK.2.0.0.1-00043-QCAHKSWPL_SILICONZ-1
* v6
- remove upstream merged mac80211 patch
- send only the ath11k relevant patches
- drop (internal DEP-3-like) "Forwarded:" tag
- switch from PATCH to RFC due to dropped HE support in ath11k
* v5
- rebased patches
- moved ath11k meshpoint HE capabilities filter to avoid lines over 80
characters
- add patch to disable HE SU phy capabilities to work around problems
with WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1 firmware
* v4
- switch order of the mac80211 HE mesh support and mac80211_hwsim support
- drop ie_len variable from ieee80211_ie_len_he_cap and
ieee80211_ie_build_he_oper
- switch to function ieee80211_get_he_iftype_cap instead of implementing new
function ieee80211_get_he_mesh_cap
- allow ieee80211_ie_len_he_cap to calculate length for non-mesh HE cap
- dropped he_support workaround in ath11k because now all phy_modes are
HE phy modes
* v3
- force ath11k PHY mode for meshpoint vif to HE mode to avoid hang of
firmware when HE (or VHT on 2.4GHz) device tries to connect
* v2:
- add of ath11k patch
* v1:
- initial RFC
