Donald Sharp 078430f609 bgpd-nht-import-check-fix.patch 
BGP: Fix network import check use with NHT instead of scanner

When next hop tracking was implemented and the bgp scanner was eliminated,
the "network import-check" command got broken. This patch fixes that
issue. NHT is used to not just track nexthops, but also the static routes
that are announced as part of BGP's network command. The routes are
registered only when import-check is enabled. To optimize performance,
we register static routes only when import-check is enabled.
