Lets assume my processing speed is less than receiving line rate so PMD rings are over run and incoming packets are getting dropped. how should i track this issue(status of mbufs and dropping packets counts in PMD). Is there any APIs or any tool available? is libtrace will help here? any help would be much appreciated. -- Thanks Sakthivel S OM ^ permalink raw reply [flat|nested] 4+ messages in thread
