SD8997 firmware sends TLV_TYPE_MAX_CONN with struct hw_spec_max_conn to
inform kernel about maximum number of p2p connections and stations in AP
mode.
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.
