Subject: RE: [PATCH 1/8] ethdev: introduce IP reassembly offload
Date: Tue, 11 Jan 2022 16:03:55 +0000 [thread overview]
Message-ID: <DM6PR11MB4491C7D99083E21DDD70B87D9A519@DM6PR11MB4491.namprd11.prod.outlook.com> (raw)
In-Reply-To: <20220103150813.1694888-2-gakhil@marvell.com>
> IP Reassembly is a costly operation if it is done in software.
> The operation becomes even more costlier if IP fragmants are encrypted.
> However, if it is offloaded to HW, it can considerably save application cycles.
>
> Hence, a new offload RTE_ETH_RX_OFFLOAD_IP_REASSEMBLY is introduced in
> ethdev for devices which can attempt reassembly of packets in hardware.
> rte_eth_dev_info is updated with the reassembly capabilities which a device
> can support.
>
> The resulting reassembled packet would be a typical segmented mbuf in
> case of success.
>
> And if reassembly of fragments is failed or is incomplete (if fragments do
> not come before the reass_timeout), the mbuf ol_flags can be updated.
> This is updated in a subsequent patch.
