4Subject: [PATCH 018/104] hostapd: MLO: send link id during flushing stations
5
6Currently, whenever a BSS is set up, it sends flush all stations via
7command - NL80211_CMD_DEL_STATION on its interface. However, in case
8of MLO, station could have been connected to other links by the time
9this link is coming up. Since there is no link id currently being
10passed, all those stations entries are also removed in the driver which is
11wrong.
12
13Hence add change to send link id along with the command during MLO so that
14the driver can use this link id and flush only those stations which are
15using the passed link id as one of its links.
