net/mlx5e: Allow set_rx_mode on uplink representor

Browse source

set_rx_mode handler was skipped on uplink representor, since uplink
relies on FDB to forward all traffic to it by default, which works
perfectly on a single PF per physical port configuration, as explicit
mac request isn't required, but In case of multi-host and DPU
environments, uplink can only use own mac address, as set_rx_mode
wasn't honored in uplink rep.

Since MPFs (Multi PF switch) requires PFs to request explicit mac
forwarding, this patch enables set_rx_mode on uplink representor to
allow PF mac programming into MPFs table in switchdev mode, allowing
use-cases such as arbitrary mac address forwarding via linux bridge.
