WAN disconnect on DST change

[rotareneg]

When the DST change occurred this morning the router disconnected and then reconnected the WAN, is that normal/intended behavior? This is with Merlin 386.5 on a RT-AC66U B1, with FlexQoS running.

Same on AC86U, but no ill effects:

Mar 13 03:00:12 rc_service: waitting "restart_firewall" via watchdog ...
Mar 13 03:00:20 WAN Connection: WAN was restored.

The router is running on Asuswrt 386_46092 firmware.

Upstream change by Asus in GPL 45581.
