Hi all,
I used gdb to trace tx procedure, but it returned at "return ops->enqueue(mp,
obj_table, n)", did not go deep anymore.
This the error drop node procedure.
Below is stack info.

Hi Ray,
It seems that it does not work, but I am not about that, please check this for
me.
VPP.mk:
vpp_uses_external_dpdk = yes
vpp_dpdk_inc_dir = /usr/include/dpdk
vpp_dpdk_lib_dir = /usr/lib
# vpp_dpdk_shared_lib = yes

VPP:

MY question is below:
I added seven interfaces to one bridge and send packets to that bridge.
The tx packets are correct, because I captured them with Wireshark on the host
system.
But there is something wrong with rte_ring.
No one put rte_mbuf back to the rte_ring, the PROD's head and tail are always
16384.
Below is some information, If you guys need more, please let me know.
(gdb) p *((struct rte_ring*)(((struct
rte_mempool*)dpdk_main->pktmbuf_pools[0])->pool_data))

Hi Xiao:
By changing dpdk driver, do you mean that you changed code in DPDK and wants to
compile VPP with modified DPDK?
If so, I recommend checking out the option to compile VPP with
“vpp_uses_external_dpdk = yes”.
Here are the steps I used:
1) Compiled DPDK with EXTRA_CFLAGS’-fPIC –pie’ and have a DESTDIR for the
compiled header/libs using whatever configuration of your choosing.
2) Modify build-data/platforms/vpp.mk to
a. Vpp_uses_external_dpdk = yes
b. Vpp_dpdk_inc_dir = <DESTDIR from step1, absolute path>/include/dpdk
c. Vpp_dpdk_lib_dir = <DESTDIR from step1, absolute path>/lib
3) Then build vpp and create packages.
This way the external dpdk is compiled as static lib and linked directly into
vpp binary. At the end you should see a few packages in build-root and they
would contain everything you need. Just install them and they should be running
with your modified DPDK.
I hope the instructions help.
Thanks,
-Ray

Hi all,
I have changed dpdk drivers, how can I make that change effective?
The cmd "dpkg -l |grep vpp" does not include anything related to dpdk.
I am look forward to hearing from u.
Regards,
