            Bug ID: 257965
           Summary: [fib_algo][dxr] inbound dropp on interfaces
           Product: Base System
           Version: 13.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs_at_FreeBSD.org
          Reporter: konrad.kreciwilk_at_korbank.pl

I have DELL R630 with ccX (Chelsio T62100-SO-CR) agreggated with lagg0 and
vlans on it. I move all vlans to JAIL (VNET). There works bird which received
full feed (900k prefixes).

When I have set:

net.route.algo.inet.algo: dxr

the inbound dropp counter for ccX is incrementing. When I use dpdk_lpm4 or
radix4 it do not happen.
