Subject: misc: Don't IPv[46] enable local0, it doesn't receive packets.
X-Git-Tag: v22.02-rc0~235
X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=refs%2Fchanges%2F73%2F32873%2F2;p=vpp.git

misc: Don't IPv[46] enable local0, it doesn't receive packets.

Type: improvement

local0 exists just to burn sw_if_index=0 so we catch common API errors.
