Hi, I am running a DPDK application on host processor. The application is bind to PCIe Host Interface of an FM10k switch. To prevent FM10k switch from sending more packets than what the DPDK application can process, the idea is to have DPDK application check the Rx Queue build up and send pause frames towards FM10k over the PCIe Host Interface.
To check Rx Queue build up, following DPDK API was looked at, and their availability for the purpose is mentioned below i. rte_eth_rx_queue_count ==> returns unsupported by all of the DPDK version’s FM10k driver. The question I have is 1) Since "rte_eth_rx_queue_count" is not supported, is there a different API that would help me find the Rx Queue build up ? 2) What would be the way to get DPDK's FM10k driver implement the "rte_eth_rx_queue_count" ? Is there someone I could request to help with the implementation ? 3) Is there any known technical reason for not having the "rte_eth_rx_queue_count" implemented in DPDK's FM10k driver ? Trying to understand if there would be anything that would block the implementation of the API in DPDK FM10k driver. Regards, Jags
