> +* librte_port (rte_port.h): Macros to access the packet meta-data stored within
> + the packet buffer will be adjusted to cover the packet mbuf structure as well,
> + as currently they are able to access any packet buffer location except the
> + packet mbuf structure. The consequence is that applications currently using
> + these macros will have to adjust the value of the offset parameter of these
> + macros by increasing it with sizeof(struc rte_mbuf). The affected macros are:
> + RTE_MBUF_METADATA_UINT<8, 16, 32, 64>_PTR and
> + RTE_MBUF_METADATA_UINT<8, 16, 32, 64>. In terms of code changes, most likely
> + only the definition of RTE_MBUF_METADATA_UINT8_PTR macro will be changed from
> + ``(&((uint8_t *) &(mbuf)[1])[offset])`` to
> + ``(&((uint8_t *) (mbuf))[offset])``.
Cristian,
General comment: you are too verbose :)
Specifically on this patch: same comment ;)
