Subject: [PATCH v3 6/7] ipv6 addrconf: change default RTR_SOLICITATION_MAX_INTERVAL from 4s to 1h

From: Maciej Żenczykowski <maze@...gle.com>

This changes:
  /proc/sys/net/ipv6/conf/all/router_solicitation_max_interval
  /proc/sys/net/ipv6/conf/default/router_solicitation_max_interval
from 4 seconds to 1 hour.

This is the https://tools.ietf.org/html/rfc7559 recommended default.
