Subject: bgpd, zebra: Pass distance as part of the ZEBRA_NEXTHOP_UPDATE
X-Git-Tag: frr-3.0-branchpoint~60^2~12
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=d14b95ce968a44a8278745fc23ac9f37e98629a1;p=matthieu%2Ffrr.git

bgpd, zebra: Pass distance as part of the ZEBRA_NEXTHOP_UPDATE

When zebra calls routing protocols back with either
ZEBRA_NEXTHOP_UPDATE or ZEBRA_IMPORT_CHECK_UPDATE
pass the distance value too.

This is to set us up for nht for pim as that it needs
the distance sometimes too.
