Subject: [dpdk-dev] Offloading L4 checksum to crypto device
Date: Mon, 23 Dec 2019 14:27:54 +0000 [thread overview]
Message-ID: <AM0PR07MB5396CD719CC621707B026CB29C2E0@AM0PR07MB5396.eurprd07.prod.outlook.com> (raw)
Hi,
This is Heng from Ericsson. We are now developing a platform based on dpdk. The platform usually processes the ipsec packets encapsulating udp packets.
You know, calculating udp checksum is always time consuming. We found a hardware solution where our crypto device can calculate the udp checksum during encryption.
Unfortunately, in DPDK, I didn't find any feature flag for it. Also the API rte_cryptodev_configure doesn't allow us to pass any offload flag to the crypto device.
I think this could be a common case to calculate something, like checksums, before encryption in crypto devices. Should we consider add some new feature flag and offload support in dpdk crypto device?
Regards,
Heng
