    net: thunderx: use proper interface type for RGMII · 29ca3b31

    The configuration of the OCTEONTX XCV_DLL_CTL register via
    xcv_init_hw() is such that the RGMII RX delay is bypassed
    leaving the RGMII TX delay enabled in the MAC:
    
    	/* Configure DLL - enable or bypass
    	 * TX no bypass, RX bypass
    	 */
    	cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL);
    	cfg &= ~0xFF03;
    	cfg |= CLKRX_BYP;
    	writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL);
    
    This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID
    and not PHY_INTERFACE_MODE_RGMII.
    
    Fixing this allows RGMII PHY drivers to do the right thing (enable
    RX delay in the PHY) instead of erroneously enabling both delays in the
    PHY.
