[dts] [PATCH V1] tests/interrupt_pmd: reduce the execution time

[Ma, LihongX]

Hi, Wenjie
It is better use the Packet function instead of execute scapy in suite.
Like:
Pkt = Packet()
Str='Ether()/IP(dst="198.0.0.1")/UDP()/Raw(\'X\'*18)'
Pkt.append_pkt(str)
Pkt. send_pkt(crb=self.tester, tx_port=txItf)
By the way, the value " txport", " mac", " txItf"  can move to outer loopback from inner loopback, because the value does not change after outer loopback.

It is unnecessary to start/close scapy when sending every packet.
The execution time could be reduced to 1 minute from 9.
