Subject: [PATCH v4 7/7] ipv6 addrconf: change default MAX_RTR_SOLICITATIONS from 3 to -1 (unlimited)

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

This changes:
  /proc/sys/net/ipv6/conf/all/router_solicitations
  /proc/sys/net/ipv6/conf/default/router_solicitations
from 3 to unlimited.

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