ipv6: mcast: fix unsolicited report interval after receiving querys
[ Upstream commit 6c6da92808442908287fae8ebb0ca041a52469f4 ]
After recieving MLD querys, we update idev->mc_maxdelay with max_delay
from query header. This make the later unsolicited reports have the same
interval with mc_maxdelay, which means we may send unsolicited reports with
long interval time instead of default configured interval time.
Also as we will not call ipv6_mc_reset() after device up. This issue will
be there even after leave the group and join other groups.
Fixes: fc4eba58b4c14 ("ipv6: make unsolicited report intervals configurable for mld")
