If I follow below guide (non-rpm), everything is OK.

[ovs-discuss] Match only the upper 3 bits of dscp field

2017-06-20 Thread Matthias May

Hi

I need to modify the tos field of ipv4 frames.
The rule I currently have for this looks something like:
ovs-ofctl add-flow br0-wlan0 "table=20 priority=100 dl_type=0x0800 nw_tos=32 
actions=mod_nw_tos:224"

I only want to match the upper most 3 bits of the DSCP field. This rule as it 
is has the obvious drawback of the rule
only matching when the lower 3 bits are 0.

When I try to create a rule with:
ovs-ofctl add-flow br0-wlan0 "table=22 priority=0 dl_type=0x0800 
nw_tos=160/0xe0 actions=load:5->nw_tos[5..7]"
I get the message;
ovs-ofctl: 160/0xe0: invalid mask for field nw_tos

The match nw_tos=160/0xff works.


The current workaround I have for this is:

ovs-ofctl add-flow br0 "table=0 priority=0 in_port=2 
actions=resubmit(,20),resubmit(,21),output:1"
ovs-ofctl add-flow br0 "table=20 priority=0 dl_type=0x0800 
actions=move:NXM_OF_IP_TOS[5..7]->NXM_NX_REG0[0..2]"
ovs-ofctl add-flow br0 "table=21 priority=0 dl_type=0x0800 reg0=4 
actions=load:5->nw_tos[5..7]"

Does anyone have a better idea how to do this?

[ovs-discuss] OVS-DPDK - TAP0 - vdev (af_packet) device is linkdown

2017-06-20 Thread Avi Cohen (A)

Hello All,

I did upgrade to dpdk-17.05 and ovs-2-7.1 and create a vdev - af_packet device 
according the config script below 
This tap device connects the ovs-dpdk to a name space
The problem is that this tap00 device is linkdown - (never reach  RUNNING state 
)  - hence no pkt is received transmitted on this interface  although the tap0 
creation in ovs is OK, 
I'm attaching  the config script and output of netstat and ifconfig in the 
namespace
Can someone please tell me how to activate the tap0 ?

Config script :


cd ../dpdk-17.05/usertools/
modprobe uio
insmod ../x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
