Xueqin,
Two comments below. Since lots of cases added by this suite, we need more description for each case.

Thanks,

Rmmod is critical action, may cause system unstable and recommend not to do  that.
Can bind to igb_uio later.

Stable for my environment now, can change it if future need.

Please add some descriptions for each function.
Help message should contain of function/input/output clarification:

"""
Send packets to dut and return testpmd output message
Input: dst_mac, vlan_id, packet size, packet number
Output: testpmd output message
"""


OK, I will add description.
