Serebryakov <lev@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |lev@FreeBSD.org --- Comment #1 from Lev A. Serebryakov <lev@FreeBSD.org> --- I have very similar problem: igb/I210, FreeBSD 12-ALPHA8 (r339009). When I enable "vlanhwtag" on server, clients on this VLAN receive UDP with broken checksums. For example, client can not obtain address via DHCP from server with enabled "vlanhwtag", because DHCP client doesn't seen answers, because they are dropped by kernel due to invalid checksum: tcpdump sees DHCPOFFER on cleint's interface but dhclient doesn't receive anything. -- You are receiving this mail because: You are the assignee for the bug.
