Many wifi drivers (e.g. ath10k using qualcomm wifi chipsets) support silent target hardware restart/recovery. Out of these drivers which support target hw restart, certain chipsets have the wifi mac sequence number addition for transmitted frames done by the firmware. For such chipsets, a silent target hardware restart breaks the continuity of the wifi mac sequence number, since the wifi mac sequence number restarts from 0 after the restart, which in-turn leads to the peer access point dropping all the frames from device until it receives the frame with the mac sequence which was expected by the AP. Add a wiphy flag for the driver to indicate that it needs a trigger for STA disconnect after hardware restart. Tested on ath10k using WCN3990, QCA6174.
