For Rockchip, need to obtain the current link speed to configure the tx clocks, (for example, in rgmii mode, 1000M link: 125M, 100M link: 25M, 10M link is 2.5M rate) and then enable gmac. So after the adjust_link(), before the start gamc, this intermediate stage needs to configure
Typo gamc
the clock according to the current link speed.
