Our commands setting accept_ra to 0 on all interfaces got lost in the
transition to procd. This remained unnoticed for a long time, as we also
enable forwarding on all interfaces, which prevents RA handling by default.
Restore the commands, while also fixing a possible race condition in the
old version.

The default fragment low/high thresholds are 3 and 4 MB. On devices with
only 32MB RAM, these settings may lead to OOM when many fragments that
cannot be reassembled are received. Decrease fragment low/high thresholds
to 384 and 512 kB on devices with less than 64 MB RAM.

heuristically based on the total amount of system RAM.
