brSetInetAddress can only set a single IP address on the bridge, and uses a method (ioctl(SIOCSETIFADDR)) that only works for IPv4. Replace it and brSetInetNetmask with a single function that uses the external "ip addr add" command to add an address/prefix to the interface - this supports IPv6, and allows adding multiple addresses to the interface. ioctl(SIOCSIFADDR) on AF_INET socket works for IPv4, on AF_INET6 socket works for IPv6 space. You need to create fd6=socket(AF_INET6, SOCK_STREAM, 0) in brInit() and do ioctl() on fd6.
Interesting information. I still prefer to use the ip command, though, as it allows me to add multiple IP addresses to an interface.
