Miller" <davem@...emloft.net>, Jérôme Pouiller <Jerome.Pouiller@...abs.com> Subject: [PATCH v2 12/65] staging: wfx: retrieve greenfield mode from sta->ht_cap and bss_conf From: Jérôme Pouiller <jerome.pouiller@...abs.com> wvif->ht_info contains useless copies of sta->ht_cap and bss_conf->ht_operation_mode. Prefer to retrieve information from the original structs instead of rely on wvif->ht_info.
