bgpd: support evpn nd ext community
EVPN ND ext community support NA flag R-bit, to have proxy ND.
Set R-bit in EVPN NA if a given router is default gateway or there is a
local
router attached, which can be determine based on local neighbor entry.
Implement BGP ext community attribute to generate and parse R-bit and
pass along zebra to program neigh entry in kernel.
Upon receiving MAC/IP update with community type 0x06 and sub_type 0x08,
pass the R-bit to zebra to program neigh entry.
Set NTF_ROUTER in neigh entry and inform kernel to do proxy NA for EVPN.
