            Bug ID: 255430
           Summary: ng_bridge don't sends broadcast packet to first found
                    link in case of error in other links
           Product: Base System
           Version: 13.0-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern

ng_bridge.c patch

When for some reason (including legitimate) sending manycast (in my case DH=
CP
reply broadcast) packet to one of multiple links of ng_bridge fails (for
example eiface is administratively brought down) the original packet isn't =
send
via first found link. This makes no sense for me as other links are tolerat=
ed
for errors. Attached patch changes this behavior as send the packet to all
links and keeps the logic to return the last seen error.
