The offload flags field (ol_flags) was 16-bits and had no further room
for expansion. This patch increases the field size to 64-bits, using up
the remaining reserved space in the single-cache-line mbuf.

NOTE: none of the values for existing flags have been changed, i.e. no
new numbers have been explicitly reserved between existing flag
definitions.

The initial series I've proposed [1][2] had on more enhancement: the
first patch [1] allowed to remove the definition of flag names in
testpmd. Indeed, this is not really good because they must be kept
synchronized with the flags in rte_mbuf. What do you think about this
patch? Should it be integrated in your series? Or later? Or never? ;)

The second patch [2] changes the value of the flags. This is not needed
now, but if we do it in the future, we should not forget to change
app/test-pmd/cmdline.c accordingly. Maybe this could go in your patch
directly as it does not hurt?

Olivier

No, it is a good change - I've just keep it out of my series for simplicity as I'm largely trying to keep the scope as small as possible. I would love to see that go in as a separate patch maybe once the mbuf rework is finished.

As above for now. Right now I'm just trying to get the structure worked out, and deal with any performance regressions that are found (such as what Pablo found last Friday :-( ).
