net/mlx5e: Set uplink rep as NETNS_LOCAL
[ Upstream commit c83172b0639c8a005c0dd3b36252dc22ddd9f19c ]
Previously, NETNS_LOCAL was not set for uplink representors, inconsistent
with VF representors, and allowed the uplink representor to be moved
between net namespaces and separated from the VF representors it shares
the core device with. Such usage would break the isolation model of
namespaces, as devices in different namespaces would have access to
shared memory.
To solve this issue, set NETNS_LOCAL for uplink representors if eswitch is
in switchdev mode.
Fixes: 7a9fb35e8c3a ("net/mlx5e: Do not reload ethernet ports when changing eswitch mode")
