.Nd Intel 10Gb Ethernet Virtual Function device
.Sh SYNOPSIS
.Cd "ixv* at pci?"
.Sh DESCRIPTION
The
.Nm
driver supports the SR-IOV Virtual Functions of Intel 82598EB,
82559, and X540-based Ethernet controller devices.
.Sh SEE ALSO
.Xr arp 4 ,
.Xr ifmedia 4 ,
.Xr intro 4 ,
.Xr ix 4 ,
.Xr netintro 4 ,
.Xr pci 4 ,
.Xr hostname.if 5 ,
.Xr ifconfig 8
.Sh HISTORY
The
.Nm
driver first appeared in
.Ox 7.7 .
.Sh AUTHORS
The
.Nm
driver was written by
Intel Corporation and ported to
.Ox
by
.An NAITO Yuichiro .
.Sh BUGS
The VF relies on
.Dq vlan-filter
to receive VLAN-tagged packets.
Because the current driver doesn't have a way to configure it,
any VLAN-tagged packets will not be passed.
Alternatively,
on the host running the primary function,
there might be a way to configure a VLAN ID.
