bgpd: Announce cumulative link bandwidth to EBGP peers
When announcing ourselves as the next hop (e.g., to EBGP peers), if the
best path has the link bandwidth extended community and it is transitive,
change the value of the link bandwidth to the cumulative downstream
bandwidth (sum of the link bandwidths of all our multipaths) as this
makes the most sense. It is also implied by
https://tools.ietf.org/html/draft-mohanty-bess-ebgp-dmz. Of course, do
not override the link bandwidth if it has been specified by policy.
Note: Transitive extended communities will be automatically passed along
to EBGP peers; this commit is updating the value that is announced to
something that is the most appropriate.
