All PHY attributes should be directly set to the transceiver after netlink. MAC attributes should be set by interface up. Currently the macparams netlink cmd contains mixed attributes of phy and mac settings. This patch moves all phy settings to the netlink receive function for setting macparams. This is the only way which doesn't change the userspace API and keep the deprecated netlink interface alive.
