It failed with a test case with below steps: 1. configure AP with WPA mode with ssid1 SimpleConnect_a_orbvt_ch1, bssid1 and channel 1. 2. connect to ssid1 and ping success. 3. wait 10 seconds which is less than IEEE80211_SCAN_RESULT_EXPIRE(30 seconds). 4. configure AP with OPEN mode with ssid2 SimpleConnect_b_z3a00_ch1, but use same bssid1 and channel 1 of step 1. 5. disconnect ssid1. 6. connect to ssid2 and ping fail. Fail reason: When run step 6, ath10k_peer_assoc_h_crypto() called cfg80211_get_bss() with bssid and chan info, but ssid1 and ssid2 have the same bssid and channel, then there have 2 entry for ssid1 and ssid2 in cfg80211. The ssid1's order is before ssid2 in bss_list, and ssid1's age is less than the expire time which is IEEE80211_SCAN_RESULT_EXPIRE(30 seconds). Then ssid1's entry is selected and ath10k_peer_assoc_h_crypto() parsed it and get the rsnie and then need_ptk_4_way is set to firmware, so data path is disallowed and it will not receive 4 way handshake for OPEN mode, so ping fail in step 6. This patch is to pass the ssid info to cfg80211_get_bss() as same as cfg80211_mlme_assoc() and cfg80211_mlme_auth(), then it will find the correct bss entry in above test case, then case success. For AP mode, the ssid info is filled in ieee80211_start_ap(), for STATION mode, it is filled in ieee80211_mgd_assoc(). Tested for both AP/STATION mode with QCA6174 hw3.2 PCI, it is success start/connect/ping for WPA/OPEN mode.
