[dpdk-dev] [PATCH v1 0/6] ethdev: add min/max MTU to device info

Building upon the discussion around [1], this series introduces MTU min
and MTU max variables. It also provides updates to PMD implementations
for ixgbe, i40e and IGB devices so that these variables are populated
for use when retrieving device info.

This series was tested with OVS DPDK and functions as expected for the
drivers listed below. But a wider selection of PMD drivers would have to
adopt this to ensure jumbo frames functionality remains for drivers not
modified in the series.

There is also ongoing discussion in [2] regarding overhead to be
considered with MTU and how this may change from device to device, this
series uses existing overhead assumptions.

This series was previously posted as an RFC in [3], this revision
removes RFC status and implements changes received in feedback.
