Hi Leon,

After merging the rdma-leon tree, today's linux-next build (x86_64
allmodconfig build) failed like this:

Caused by commit

cbd0624cc927 ("IB/mlx5: Expose Q counters groups only when they are supported by FW")

interacting with commit

fbcb2b5c3749 ("B/mlx5: Add port counter support for Receive WQs")

This needed to be fixed up in the merge commit

3064f9066da1 ("Merge branch 'topic/q_counters' into rdma-next")

I have dropped the rdma-leon tree again for today.
