Not sure what it exactly fixes?
As I remember these flags don't specify any TX offload for HW to perform,
But just provide information to the TX function.
Again, why only i40e code is modified?
As I remember we have the same code in other PMDs too.

Also, it looks like MACSEC is missing. To avoid forgetting flags in
the future, what do you think about doing the following (not tested)?

I see your point but should, let say, PKT_TX_IPV4 be part of PKT_TX_OFFLOAD_MASK at all?
It doesn't really define any offload for PMD/HW to perform.
It just provide extra information for PMD so it can successfully process other offload requests.

Yes, that's right. On the other hand, differentiating them may confuse
the PMD developpers (that's probably the case for this patch).
Having PKT_TX_MASK that includes all TX flags automatically would also
do the job (knowing PMDs must be updated), and would avoid to forget
flags in the future... if we decide to do it, it would be better before
17.02, because PKT_TX_OFFLOAD_MASK was added after 16.11, so it is not
yet part of the API.
In any case, we need a patch to fix the missing PKT_TX_MACSEC in
PKT_TX_OFFLOAD_MASK.

Some Tx offload flags are missed in bitmask of all supported packet
Tx offload features flags.
This patch fixes it.
Fixes: 4fb7e803eb1a ("ethdev: add Tx preparation")
