    ipq40xx: enable RX hash / CTAG TX offloading for single-phy
    
    This re-enables offloading features disabled by
    commit 9da2b567605b ("ipq40xx: fix ethernet vlan double tagging").
    
    Single-PHY devices use port-based VLANs on the switch, therefore no
    S-TAG magic is involved here. Re-enabling these features restores
    throughput back to 950 Mbit/s.
