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
