result of this function was always a pointer to the first header
matching the level.

Modify the unlock code for a route_node to return NULL on
pointer freed or to return the node itself again.
We'll need to go through the code and fix this pattern,
but this is a problem for another day. Get this fix in
place and we can make it a low hanging problem to fix.

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.
