In my case DHCP fails with the error below. Disabling RXCSUM makes it work immediately. vtnet0: flags=3D1008802<BROADCAST,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu = 1500 =20=20=20=20=20=20=20 options=3D4c07bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSU= M,TSO4,TSO6,LRO,VLAN_HWTSO,LINKSTATE,TXCSUM_IPV6> ether 00:16:3e:e2:a7:60 media: Ethernet autoselect (10Gbase-T <full-duplex>) status: active nd6 options=3D29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> lo0: flags=3D1008049<UP,LOOPBACK,RUNNING,MULTICAST,LOWER_UP> metric 0 mtu 1= 6384 options=3D680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6> inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2 groups: lo nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL> root@:/mnt/root # dhclient vtnet0 DHCPDISCOVER on vtnet0 to 255.255.255.255 port 67 interval 4 DHCPDISCOVER on vtnet0 to 255.255.255.255 port 67 interval 6 DHCPDISCOVER on vtnet0 to 255.255.255.255 port 67 interval 9 DHCPDISCOVER on vtnet0 to 255.255.255.255 port 67 interval 9 DHCPDISCOVER on vtnet0 to 255.255.255.255 port 67 interval 13 5 bad udp checksums in 5 packets DHCPDISCOVER on vtnet0 to 255.255.255.255 port 67 interval 13 ^C root@:/mnt/root # ifconfig vtnet0 -rxcsum root@:/mnt/root # dhclient vtnet0 DHCPDISCOVER on vtnet0 to 255.255.255.255 port 67 interval 3 DHCPOFFER from 10.86.126.1 DHCPREQUEST on vtnet0 to 255.255.255.255 port 67 DHCPACK from 10.86.126.1 bound to 10.86.126.96 -- renewal in 1800 seconds. --=20 You are receiving this mail because: You are the assignee for the bug.=
