Tx descriptor for TSO embeds packet header to be replicated. If Tx inline
is enabled, there could be additional packet data inlined with 4B inline
header ahead. And between the header and additional inlined packet data,
there may be padding to make the inline part aligned to
MLX5_WQE_DWORD_SIZE. In calculating the total size of inlined data, the
size of inline header and padding is missing.
Fixes: 3f13f8c23a7c ("net/mlx5: support hardware TSO")

Is not it dangerous to assume inl will always be 4 bytes long? Why not
writing the real value instead?

That was for readability of the code and uint32_t will be always 4bytes. But for
better readability, it should be 'inline_header' instead of 'inl' though. I'm
also okay with using "4" as well. Which way do you prefer?

I agree on both, I was not clear enough to explain my thought, if for some
reason the inl moves from uint32_t to uint16_t without touching the sizeof
later, it will cause an issue.

I tried to change the sizeof but I found that there are more "sizeof(inl)" in
the following lines. Changing all the sizeof would be beyond the scope of this
patch. So, how about leaving it as is for consistency?

The inline segment format is not expected to change so easily. It is parsed by the HW and HW maintains backward compatibility for all of the WQE structures.

We are not talking here about the hardware behavior but about wrong ways to
define hardware values which should be used trough define and not by size of
variable which can be wrongly modified.
If the hardware inline_header size of 4, it should be defined as is.
I won't block this patch as it is not the single place where this sizeof is
used, but it should be replaced as soon as possible by a define to avoid wrong
behaviors in the future.
