Subject: network performance get regression from 2.6 to 3.10 by each version

I have an ARM platform which works with older 2.6.28 Linux Kernel and
the embedded NIC driver
I profile the TCP Tx using netperf 2.6 by command "./netperf -H
{serverip} -l 300".

In 2.6.28 the TCP tx can reach 190 Mbps.

Recently I am porting the platform to long-term Kernel version
2.6.32.61, 3.4.88 and 3.10.
And I got the regression TCP Tx throughput by each new version.

2.6.32.61 is about 184Mbps
3.4.88 is about 173Mbps
3.10.0 is about 160Mbps

so, I try to porting to more EOL versions

3.0.38  184Mbps
3.2.0   179Mbps
3.2.57 177Mbps
3.5.0   168Mbps
3.5.7   166Mbps
3.6.0   162Mbps
3.6.11   163Mbps

The newer version have slower performance.

The Kernel was download from kernel.org for porting.
To touch less file as possible, I only porting basic requirement for
MACHINE_START "io_map" "interrupt" "timer" and add NIC driver.
The patch needed for NIC driver from 2.x to 3.x is only to group fops
to "net_device_ops". No any change in xmit, received and isr handle
flow.
Actually, the NIC driver from 3.2 to 3.6 are file identical by diff.
The only different is .config file, and I have try to keep the
configuration are identical also. Just new or remove option difference
between each version.
I have no idea is the performance regression is due to network stack
of each version or any feature I have to configure on new version.
Any suggestion I can try to dig out the root cause, or some one have
similar same observation on your experimence?

The following is .config which I used for 3.0.38 and .config diff
between each version.
I can't find any difference option will effect the performance from
.config diffs.
