It seems like there is an issue with the e1000 driver I have used, bhyve
aborts with

rdmsr to register 0x3a on vcpu 0
e82545: TSO hdrlen too small for vlan insertion (0 vs 12) -- dropped
e82545: TSO hdrlen too small for vlan insertion (0 vs 12) -- dropped
Assertion failed: (dtype == ntype), function e82545_transmit, file
/usr/src/usr.sbin/bhyve/pci_e82545.c, line 1137.
Abort trap
rdmsr to register 0x3a on vcpu 0
Segmentation fault


When using virtio-net the VM works without flaws, found the
corresponding bug (218715) and commented.
