Hi Qiming, Wenjun, Yu,

For me changes looks good but this set changes ixgbe bypass 
configuration in testpmd, instead of it being enabled by default, now an 
explicit command needs to be issued. This also can affect bypass testing.

Can you please test/comment on the set for the ixgbe bypass? For both 
functional and dts testing perspective?

Thanks,
ferruh
