However, mac80211 does not populate he_oper.params for AP mode, causing the BA mode configuration to be skipped for HE AP operation. Move the BA mode configuration outside the he_oper.params check so that it is applied whenever HE support is enabled. Without this change, firmware defaults to a BA buffer size of 64 (legacy mode) for HE associations.
