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.=20 For example, client can not obtain address via DHCP from server with enabled "vlanhwtag", because DHCP client doesn't seen answers, because they are dro= pped by kernel due to invalid checksum: tcpdump sees DHCPOFFER on cleint's inter= face but dhclient doesn't receive anything. --=20 You are receiving this mail because: You are the assignee for the bug.=
