Logically it offers 4 SGMII +interfaces multiplexed onto the same physical lanes. Each MAC PCS has +its own in-band AN process with the system side of the QSGMII PHY, which +is identical to the regular SGMII AN process. + +So allow QSGMII as a valid in-band AN mode, since it is no different +from software perspective from regular SGMII. + +Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> +--- + drivers/net/phy/phylink.c | 1 + + 1 file changed, 1 insertion(+) + +--- a/drivers/net/phy/phylink.c ++++ b/drivers/net/phy/phylink.c +@@ -283,6 +283,7 @@ static int phylink_parse_mode(struct phy + + switch (pl->link_config.interface) { + case PHY_INTERFACE_MODE_SGMII: ++ case PHY_INTERFACE_MODE_QSGMII: + phylink_set(pl->supported, 10baseT_Half); + phylink_set(pl->supported, 10baseT_Full); + phylink_set(pl->supported, 100baseT_Half); |
