br_ip6_multicast_mld2_report function uses icmp6h to parse mld2_report packet. mld2r_ngrec defines mld2r_hdr.icmp6_dataun.un_data16[1] in include/net/mld.h. So, it is more compact to use mld2r rather than icmp6h. By doing printk test, it is confirmed that icmp6h->icmp6_dataun.un_data16[1] and mld2r->mld2r_ngrec are indeed equivalent. Also, sizeof(*mld2r) and sizeof(*icmp6h) are equivalent, too. Signed-off-by: MichelleJin <shjy180909@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
