Subject: [PATCH] icmp6 fix no respond to neighbor solicit message
ecb9bb
ecb9bb
The structure size used in grub_netbuff_pull to get the pointer to
ecb9bb
option header is apparently wrong, which leads to subsequent range check
ecb9bb
failed and therefore not responding to any neighbor solicit message in my
ecb9bb
testing.
