Hi all, We've been running some benchmarks (Netperf, Iperf) on our driver (Mellanox= ), and witnessed an odd behavior. We saw that when running UDP traffic with msg size larger than 9215 bytes, = it gets dropped for some reason. MTU is 1500. We've spotted the same behavior on different vendors which lead us to belie= ve there's some kernel issue that we are missing here. Please advise, Meny Yossefi | SW Engineer Mellanox Technologies Ltd Work: +972-74-7129121, Cell: +972-52-8379557
