Did you tried 'mk/rte_app.mk' to build you application?
Simply including -lrte_pmd_xxx may cause problem because
PMD_REGISTER_DRIVER uses 'init' attribute,
which is called before the 'main' function.
See the 'start-group' and 'whole-archive' linker options.

We found that optimizing fragmentation configuration of mlx4 driver
performs as fast as native PMD.
I think we have to re-consider using native driver rather than ib driver.

Answer 1. UIO based driver is faster then ib based driver.
It can saturate 40G link with MTU sized packets using a single thread while
ib wrapper cannot.
Answer 2. Sorry, I missed that. I'll make a new patch email with my real
name.
Question 1. Is it OK if I separate GPL-based and BSD-based
for your answer.

I have not used XL710 or i40e.
I have no opinion for those NICs.

Did you set RSS mode?
Multi-queue RX won't work unless you have set RSS(Receive Side Scaling).

I don't know your situation exactly, but here are possible problems.
1. Your switch learned MAC addresses of two ports.
2. Your program bug.
3. l3fwd itself contains some bug.
4. You did not set all ports in promiscuous mode.
You'd better try 'pktgen' application to test your environment.
DPDK's igb_uio driver does not generate 'netdev' interfaces,
so you cannot see any interface via ifconfig.
(However, they are registered as 'rte_eth_dev' in your DPDK application.)
You'd better to use KNI drivers to have 'netdev' intefaces.

As I know, intel 82599 is the only 10G NIC which supports line rate with
minimum sized packets (64 byte).
According to our internal tests, Mellanox's 40G NICs even support less than
30Mpps.
I think 40 Mpps is the
...and -c option gives 'masking' for CPUs.
-c 1 will only activate single core (especially second core) of your system.
If you want to activate both core, you have to give the mask '11'b ('3' in
decimal).

See your motherboard spec.
For example, I'm using Intel 5930K with ASUS X99 Delux Motherboard (x99
chipset).
This site https://www.asus.com/us/Motherboards/X99DELUXE/specifications/
tells that
"Quad Channel Memory Architecture "
which means that "-n 4" is the correct configuration for me.
To
http://dpdk.org/browse/dpdk/tree/app/test-pmd/ieee1588fwd.c
This code example contains enabling PTP with intel NICs.

82599 supports hw timestamping for PTP packets.
I don't know whether it supports timestamping for general packets.
http://lxr.free-electrons.com/source/drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c#L640
says that
640
How fast does this driver perform?
Is it capable for sending/receiving 64B packets at 40G line rate?
I'm using another version of user driver and it is not scalable for line
rate, regardless of the number of TX cores.

I think this should be removed. This causes compile error on C++.

Hi.
I just pulled new patches from the master branch, and found that it doesn't
work with C++.
in lib/librte_eal/common/include/generic/rte_cycles.h
missing opening extern "C" in
commit fa4001c30ee9d9ecfb3ca5d93d68ef0394e9950a
here is the fix.
-
* Simple Time Reference Functions (Cycles
In DPDK1.7, PMDs are loaded by __constructor__ functions.
As there is no direct reference to each PMD driver structures, linker may
not link the PMD library.
You should use -Wl,--whole-archive and -Wl,--no-whole-archive for linking
DPDK applications.
