Re: [dts] Clarifications on setting up DUT

[Ravi Kerur <rkerur@gmail.com>]

Hi Michael,

I got 2 systems assembled which had I217 and I218 chipsets on the
motherboard and I  was not quite satisfied with the testing I did to claim
support for these chipsets (primarily used testpmd for testing) so looked
at DTS to complement the testing I did.

<rk> Issue was primarily with delay to acquire v6 address after link up.
There are some test cases in DTS for 1 port and I am testing with them
