Would it be simpler to add 'q_ierrors' & 'q_oerrors' to 'struct rte_eth_stats'? And perhaps we can do the 'fix rxq q_errors' patchset [1] after this change, so fix can be done with less changes, although it will push the fix into next release because of the ABI break. OR ethdev will be broken this release, because of max_mtu, since ABI is already broken perhaps we can squeeze this in. Overall I would like to get more comment on this, Andrew, Thomas? > > Signed-off-by: David Marchand <...>
