currently on r41181.
since some weeks(?) my wds link is a bit unstable, with the wds-client
often losing connectivity. the wifi link appears to be up, but won't pass
any traffic. often this self corrects within minutes, other times I've had
to reboot the wds-client.
seeing this in dmesg on the wds-ap:
