Add the last missing constant of the USXGMII UsxgmiiChannelInfo field. Unfortunately, there is no meaningful name in the USXGMII Singleport Copper Interface specification. The specification just describe that it has to be set to 1. The corresponding SGMII macros has two different defines, ADVERTISE_SGMII and LPA_SGMII, depending on the direction. The USXGMII is symmetrical thus just call it MDIO_USXGMII_ADVERTISE. Signed-off-by: Michael Walle <michael@walle.cc> --- This is flagged as RFC to prevent the autobuilder bots from picking up this patch because it depends on the following series: https://lore.kernel.org/netdev/20200719220336.6919-1-michael@walle.cc/ I'm sending this as a separate patch because Russell put his Reviewed-by: tag on everything else but this. include/uapi/linux/mdio.h | 1 + 1 file changed, 1 insertion(+)
