Subject: [PATCH] net/mlx5: reject jump to root table
Date: Tue, 18 Jan 2022 19:35:37 +0800	[thread overview]
Message-ID: <798beef100ce147f20e03f7590c7770e56a246cc.1642505511.git.jackmin@nvidia.com> (raw)

Currently root table as destination is not supported.
The jump action which finally be translated to underlying root table in
rdma-core should be rejected.

Fixes: f78f747f41d0 ("net/mlx5: allow jump to group lower than current")
