During initialization of SD8997 wifi chip kernel prints warning: mwifiex_sdio mmc0:0001:1: Unknown GET_HW_SPEC TLV type: 0x217 This patch adds support for parsing TLV_TYPE_MAX_CONN (0x217) and sets appropriate cfg80211 member 'max_ap_assoc_sta' from retrieved structure. It allows userspace to retrieve NL80211_ATTR_MAX_AP_ASSOC_STA attribute.
