--------------------------------
[ Upstream commit 52eda4641d041667fa059f4855c5f88dcebd8afe ]
There is a typo in the driver due to which we report incorrect TX RMON counters for the 256-511 octet bucket and all the other buckets larger than that.
Bug found with the selftest at https://patchwork.kernel.org/project/netdevbpf/patch/20231211223346.2497157-...
