====================
bridge: implement rtnl_link options for getting and setting bridge options

So far, only sysfs is complete interface for getting and setting bridge
options. This patchset follows-up on the similar bonding code and
allows userspace to get/set bridge master/port options using Netlink
IFLA_INFO_DATA/IFLA_INFO_SLAVE_DATA attr.
