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.
