[PATCH v1 0/4] Add second scatter test case

[jspewock@iol.unh.edu]

From: Jeremy Spewock <jspewock@iol.unh.edu>

The current test suite for testing the scatter gather capabilities of a
NIC currently does not support Mellanox NICs since these NICs require
that you first enable the scattered_rx offload when you start testpmd,
but some other PMDs do not. This patch series adds an expansion of the
scatter test suite which has a test case that tests the functionality
with the offload, and it leverages the capabilities patch to enforce
that the previous test case gets skipped when not supported.

Additionally, since this is the first time we are running testpmd
multiple times in a row, more improvements were added surrounding the
usage of interactive shells in order to make things like the starting
and cleanup more consistent.

Jeremy Spewock (4):
  dts: improve starting and stopping interactive shells
  dts: add context manager for interactive shells
  dts: add methods for modifying MTU to testpmd shell
  dts: add test case that utilizes offload to pmd_buffer_scatter
