- rebase
changes in v11:
patch 1/9:
- fix return values in ath12k_mac_set_he_txbf_conf() and
ath12k_mac_vif_recalc_sta_he_txbf()
patch 6/9:
- fix missing he_mcs initialization in ath12k_mac_init_arvif()
changes in v10:
patch 6/9:
- use ath12k_ahsta_to_sta()
- fix rcu_dereference warning in ath12k_mac_set_bitrate_mask_iter()
- change return type for ath12k_mac_validate_fixed_rate_settings()
- improve readability by adhering to nl80211 definitions of GI
NL80211_TXRATE_DEFAULT_GI. Introduce ath12k_mac_nlgi_to_wmigi()
for conversion.
patch 7/9:
- do not change default MODE_11AC_VHT160 in
ath12k_mac_get_phymode_vht() as it breaks clients which do not
set VHT_CAP_SUPP_CHAN_WIDTH_160MHZ.
patch 8/9:
- Use IEEE80211_VHT_CAP_EXT_NSS_BW_MASK along with
IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ for determining VHT160
phymode.
changes in v9: rebase on top of master branch with mlo changes
patch 1/9 and 2/9:
- fetch link_conf using ath12k_mac_get_link_bss_conf()
instead of arvif->vif->bss_conf before mlo
patch 6/9
- fetch mcs/nss values from sta->link[] instead of sta->deflink
- fix spelling of 'incompatibility'
patch 8/9
- replace sta->deflink.addr with arsta->addr in
ath12k_peer_assoc_h_vht
patch 9/9
- replace sta->deflink.rx_nss with link_sta->rx_nss
changes in v8:
- rebase and resolve KASAN warnings reported by Jeff in v7, in patch 6/9.
