net: thunderx: use proper interface type for RGMII
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.
