+.Sh NAME
+.Nm ixv
+.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 netintro 4 ,
+.Xr pci 4 ,
+.Xr hostname.if 5 ,
+.Xr ifconfig 8
+.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.
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Ox 7.7 .
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+Intel Corporation and ported to OpenBSD by NAITO Yuichiro.
