Changes in v2:
* fix a nasty typo in PATCH 1/4, br_multicast_update_query_timer():
"br->multicast_query_interval" vs. "br->multicast_querier_interval"
=> this accidentally reduced the other querier present timer
from 255 to 125 seconds
* fix a typo in PATCH 2/4, br_ip{4,6}_multicast_query():
ntohs(ETH_P_{IP,IPV6}) vs. htons(ETH_P_{IP,IPV6})
* add missing ntohl()s before address comparison in PATCH 2/4,
br_ip4_multicast_select_querier() (thanks David!)
Cheers, Linus
