net/mlx5e: Don't allow forwarding between uplink
We can install forwarding packets rule between uplink in switchdev mode, as show below. But the hardware does not do that as expected (mlnx_perf -i $PF1, we can't get the counter of the PF1). By the way, if we add the uplink PF0, PF1 to Open vSwitch and enable hw-offload, the rules can be offloaded but not work fine too. This patch add a check and if so return -EOPNOTSUPP. $ tc filter add dev $PF0 protocol all parent ffff: prio 1 handle 1 \ flower skip_sw action mirred egress redirect dev $PF1 $ tc -d -s filter show dev $PF0 ingress skip_sw in_hw in_hw_count 1 action order 1: mirred (Egress Redirect to device enp130s0f1) stolen ...
