There is a function in mdio for the old ethtool api gset.
We add a new function mdio45_ethtool_ksettings_get for the
new ethtool api glinksettings.

This translates cmd->link_modes.supported in to the legacy supported
bitmap before we've actually read the values from the phy. Given we're
only using the legacy bitmap so we can add the pause frame settings, I
suggest something like:
ef4_ethtool_get_link_ksettings(struct net_device *net_dev,
struct ethtool_link_ksettings *cmd)
{
struct ef4_nic *efx = netdev_priv(net_dev);
struct ef4_link_state *link_state = &efx->link_state;
mutex_lock(&efx->mac_lock);
efx->phy_op->get_link_ksettings(efx, cmd);
mutex_unlock(&efx->mac_lock);
/* Both MACs support pause frames (bidirectional and respond-only) */
ethtool_link_ksettings_add_link_mode(cmd, supported, Pause);
ethtool_link_ksettings_add_link_mode(cmd, supported, Asym_Pause);
if (LOOPBACK_INTERNAL(efx)) {
cmd->base.speed = link_state->speed;
cmd->base.duplex = link_state->fd ? DUPLEX_FULL : DUPLEX_HALF;
}
return 0;
}
Thanks,
Bert.
