This is because of setting the IEEE80211_SDATA_DISCONNECT_HW_RESTART flag very early in the hardware recovery process even before the driver invokes ieee80211_hw_restart(). On the contrary, mac80211 expects this flag to be set after ieee80211_hw_restart() is invoked for it to trigger station disconnect. Set the IEEE80211_SDATA_DISCONNECT_HW_RESTART flag in ath10k_reconfig_complete() instead to fix this. The other targets are not affected by this change, since the hardware params flag is not set.
