I'm not able to get this working on PCB135. I tested the VLAN tags and
did not work either (did not test the rest). The example from the
previous patch series doesn't work either after applying this series.

tc qdisc add dev eth3 clsact
tc filter add dev eth3 ingress chain 8000000 prio 10 handle 10 \
	protocol all flower skip_sw \
	dst_mac 0a:0b:0c:0d:0e:0f \
	src_mac 2:0:0:0:0:1 \
	action trap

This example was provided in your last patch series and worked earlier.

My setup is PC-eth0 -> PCB135-eth3 and I use the following EasyFrames
command to send packets:

ef tx eth0 rep 50 eth smac 02:00:00:00:00:01 dmac 0a:0b:0c:0d:0e:0f

IPv4:
tc qdisc add dev eth3 clsact
tc filter add dev eth3 ingress chain 8000000 prio 12 handle 12 \
    protocol ip flower skip_sw dst_ip 1.0.1.1 src_ip 2.0.2.2    \
    action trap

ef tx eth0 rep 50 eth smac 02:00:00:00:00:01 dmac 0a:0b:0c:0d:0e:0f ipv4 dip 1.0.1.1 sip 2.0.2.2

Same setup as above and I can't get this to work either.

I'm using tcpdump to watch the interface to see if the packets are being
trapped or not. Changing the packets' dmac to broadcast lets me see the
packets so I don't have any issue with the setup.

Casper
