[dts] [PATCH] L3fwd: Enable RFC2544 for some 2 ports cases

[Ding Heng]

Enable RFC2544 test for l3fwd 2 ports cases. In order to save time, only
1S/1C/1T and 1S/4C/1T cases will be enabled, the others' result will be set 0.

Hi Heng,

One question about RFC2544 test.

According to https://tools.ietf.org/html/rfc2544, one minute is enough for trial. Wait for two minutes maybe too long for validation.
And frame should be [64, 128, 256, 512, 1024, 1280, 1518], maybe you can reference it.

Not sure why not "lpm" mode and 1C/4C need RFC2544 test.  Could you clear it?
