To be sure we're on the same page, let me reword:

- mbufs passed to tx_prepare() by the application must have their
  headers (l2_len + l3_len + l4_len) writable because the phdr checksum
  can be replaced. It could be precised in the api comment.

- mbufs passed to tx_burst() must not be modified by the driver/hw, nor
  by the application.


About the API itself, I have one more question. I know you've
already discussed this a bit with Adrien, I don't want to spawn a new
big thread from here ;)

The API provides tx_prepare() to check the packets have the proper
format, and possibly modify them (ex: csum offload / tso) to match hw
requirements. So it does both checks (number of segments) and fixes
(csum/tso). What determines things that should be checked and things
that should be fixed?

The application gets few information from tx_prepare() about what should
be done to make the packet accepted by the hw, and the actions will
probably be different depending on hardware. So could we imagine that
in the future the function also tries to fix the packet? I've seen your
comment saying that it has to be an application decision, so what about
having a parameter saying "fix the packet" or "don't fix it"?

About rte_eth_desc_lim->nb_seg_max and
rte_eth_desc_lim->nb_mtu_seg_max, I'm still quite reserved, especially
for the 2nd one, because I don't see how it can be used by the
application. Well, it does not hurt to have them, but for me it looks a
bit useless.

Last thing, I think this API should become the default in the future.
For instance, it would prevent the application to calculate a phdr csum
that will not be used by the hw. Not calling tx_prepare() would require
the user/application to exactly knows the underlying hw and the kind of
packet that are generated. So for me it means we'll need to also update
other examples (other testpmd engines, l2fwd, ...). Do you agree?

Olivier
