Better to use static unsigned int instead of static unsigned.

I intended to reply to the v2 email not the v1 email (previous reply).

"sec[1 + i]" cast to tlv struct, and "i" increased by tlv->len, can you
please confirm tlv->len is measure of tlv_section_record, not bytes.

Is there an assumption that for this type, info_size is measure of
records instead of input buffer size in bytes as other types? I believe
info_size should be consistent between types.

Same as above, info_size assumed to number of structs, not size in bytes.

Just to double check, both types PCTYPE_LIST and PTYPE_LIST types are
returning "rte_pmd_i40e_ptype_info"? So no specific struct for pctype?

This overwrites one line above, intentional?

This is not part of this patch, but out of curiosity, what is the use
case of defining a max in enum with a fixed number?
