This series adds support for setting & retrieving per packet protocol specific metadata. This is primarily required by the application to monitor sequence number overflows in inline protocol processing.
The feature is added to the existing set_pkt_metadata API. The existing API passes all arguments directly. This series introduces a new structure which could be used to pass all metadata required in such cases. The patch set adds the ability to both set & retrieve such parameters. The idea is to make the application determine the sequence number to be used, where it is supported. If the PMD doesn't support it that way (as in the parameters are maintained by PMD/device), then application could just retrieve the value and see if there is any overflow etc happening. SA expiry/overflow monitoring requires knowing the latest sequence number on an SA. So this change allows that ability - for now for the outbound SA.
