[dts] [PATCH] framework tester: support parameter in integrity function

[dts] [PATCH] framework tester: support parameter in integrity function

[Yong Liu]

In some cases, there's a need to configure random packet settings like
destination mac address. Params should be list of packet.config_layer's
arguments. Here's one sample.

params=[("ether", {'dst': 'ff:ff:ff:ff:ff:ff', 'src':
"00:20:00:00:00:00"})]
