bgpd: efficient NLRI packing for AFs != ipv4-unicast
ISSUE:
Currently, for non-ipv4-unicast address families where prefixes are
encoded in MP_REACH/MP_UNREACH attributes, BGP ends up sending one
prefix per UPDATE message. This is quite inefficient. The patch
addresses the issue.
PATCH:
We introduce a scratch buffer in the peer structure that stores the
MP_REACH/MP_UNREACH attributes for non-ipv4-unicast families. This
enables us to encode multiple prefixes. In the end, the two buffers
are merged to create the UPDATE packet.
