Subject: net/mlx5e: Create q counters on uplink representors
Patch-mainline: v5.6-rc1
Git-commit: 8520fa57a4e934eff631883cf80744d3a84c734b
References: jsc#SLE-8464
Q counters were disabled for all types of representors to prevent an issue
where there is not enough resources to init q counters for 127 representor
instances. Enable q counters only for uplink representors to support
"rx_out_of_buffer", "rx_if_down_packets" counters in ethtool.
