====================
bridge: netlink: complete port attribute support

This is the second set that completes the bridge port's netlink support and
makes everything from sysfs available via netlink. I've used sysfs as a
guide of what and how to set again. I've tested setting/getting every
option and also this time tested enabling KASAN. Again there're a few long
line warnings about the ifla attribute names in br_port_info_size() but
as the previous set - it's good to know what's been accounted for.
