X-BeenThere: dev@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 27 Jul 2014 09:58:42 -0000 Hi all, Is there, on dpdk 1.6, an API for controlling the receive timer (EITR) expiration of the wthresh on the NICs? when setting, for example, .wthresh to 4 and transmitting 7 packets to the application, then the last 3 packets remains in the on-chip-buffer for too long and are written to the host memory only after few seconds, which is not acceptable (in my case using 82575). is there a way to config this? Thanks Sim
