HI,

         I am using DPDK 16.07 example loadbalancer to as LB to forward vla=
n pkt to applications. LB and applications are using VFs bound with DPDK ig=
b_uio driver.
But I found the packet can not be send from LB to application. Pkt input to=
 LB with vlan, after LB processing it is sent out to application using anot=
her VF.

As 82599 need vlan filters if we use VF to process vlan pkts, in the LB we =
called rte api to add a vlan filter and enable vlan flilter. And set port_c=
onf with vlan strip off.
And for the application(L2FWD) we use the cmd: ip link set PFxxx VF yy vlan=
 VLANID.

In the LB ,we can receive pkts with vlan, after processing(cut the head and=
 add another L2 head with same vlan tag, set destination MAC to application=
 VF), it is send out to the application VF.
the result is: LB can still processing ,but all the pkt post.

We also did an experiment using testPMD to forward vlan pkt to application =
on the same VF used by LB, and it is OK.
We tried kinds of different set of vlan filter, vlan strip, ip link set, bu=
t found no solution.

Does anyone meet the similar problem? And what factor casued the difference=
?

Thx.
