commit be55d3e76c0ed422c35f8e98c09bce77886609af
bugzilla: https://gitee.com/openeuler/kernel/issues/I56NE7

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=be55d3e76c0ed422c35f8e98c09bce77886609af

--------------------------------

commit 07666c75 upstream.

Match metadata support check returns false for ecpf device.
However, this support does exist for ecpf and therefore this
limitation should be removed to allow feature such as stacked
devices and internal port offloaded to be supported.

Fixes: 92ab1eb3 ("net/mlx5: E-Switch, Enable vport metadata matching if firmware supports it")
