Subject: Fwd: pktgen with vlan packets

Hi,

Im running 2.6.35 kernel with an Intel 82599 NIC.
I want to send packets using pktgen via a number of vlan interfaces (1
physical interface) created via vconfig but I get an OOPs when I try
and send via the vlan interface.  See attached log file for the oops.
Im not using the pgset "vlan_id 77" params because I want to send
packets with more than 1 VLAN tag to one interface. (If it was
possible to send packets with different vlan tags over the one
interface with pktgen I would use it)

my config is as follows:
  ifconfig eth4 up
  modprobe 8021q
  vconfig add eth4 256
  ifconfig eth4.256 up

My pktgen config is the exact same as
ftp://robur.slu.se/pub/Linux/net-development/pktgen-testing/examples/pktgen.conf-1-1
except that instead of eth1, I have eth4.256.

Any ideas as to how I can send packets with multiple VLAN tags over
the same interface with pktgen?

Regards
Jonathan
