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.
