BGP: Set SO_MARK on connecting sockets to ensure lookup in right routing table
In the presence of a function such as management VRF/MRF, bgpd needs to be able
to specify that it intends to run in the dataplane and not the front panel.
To ensure this, we add a mark in the connecting socket so that the kernel
does the routing lookup in the right table. This assumes that an appropriate
ip rule has been configured (outside the scope of this package).
While we've forced the mark to be 254 for now, it maybe required to make it
configurable at a later time.
