To be a bit more specific it would be good to have IF-MIB ifTable with the
items from ifXTable as well:
A number of things are missing or weird in the DPDK stats interface. Then I
get stuck trying to maintain them in my app instead and it's annoying.
Also, it is nice to get the struct populated atomically so the values are as
self-consistent as possible. If you have to call a function separately on each
stat it makes them self-inconsistent because it is less atomically populated.
