Probably all ath(4) devices have same issue. This results in STAs not discarding to unicast frames address to the new MAC. >How-To-Repeat: COLD START two RSPRO with FreeBSD HEAD. RSPRO1# ifconfig ath0 ether 00:01:02:00:00:01 RSPRO1# ifconfig wlan create wlandev ath0 wlanmode mesh channel 1 meshid test RSPRO1# ifconfig wlan0 192.168.3.1 RSPRO2# ifconfig ath0 ether 00:01:02:00:00:02 RSPRO2# ifconfig wlan create wlandev ath0 wlanmode mesh channel 1 meshid test RSPRO2# ifconfig wlan0 192.168.3.2 Running 'athregs -i ath0 | grep STA' on both RSPRO reveals that the chip still has the old mac address registered as it's STA_ID0 (station id). Pining between the RSPROs does not work. >Fix: Workaround: Running 'ifconfig ath0 up' just after setting new mac address seems to update the STA_ID0 register to the new mac address. >Release-Note: >Audit-Trail: >Unformatted:
