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 believe there's some kernel issue that we are missing here.
Please advise,
