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,
