> Subject: [PATCH v4 1/3] ethdev: introduce IP reassembly offload
>
> IP Reassembly is a costly operation if it is done in software.
> The operation becomes even more costlier if IP fragments are encrypted.
> However, if it is offloaded to HW, it can considerably save application
> cycles.
>
> Hence, a new offload feature is exposed in eth_dev ops for devices which can
> attempt IP reassembly of packets in hardware.
> - rte_eth_ip_reassembly_capability_get() - to get the maximum values
> of reassembly configuration which can be set.
> - rte_eth_ip_reassembly_conf_set() - to set IP reassembly configuration
> and to enable the feature in the PMD (to be called before
> rte_eth_dev_start()).
> - rte_eth_ip_reassembly_conf_get() - to get the current configuration
> set in PMD.
>
> Now when the offload is enabled using rte_eth_ip_reassembly_conf_set(),
> the resulting reassembled IP packet would be a typical segmented mbuf in
> case of success.
>
> And if reassembly of IP fragments is failed or is incomplete (if fragments do
> not come before the reass_timeout, overlap, etc), the mbuf dynamic flags can
> be
> updated by the PMD. This is updated in a subsequent patch.
