This patchset adds the code for waiting chip to clean the all pkts(TX & RX) in chip when the driver uses the function named "adjust link". This patchset cleans the pkts as follows: 1) close rx of chip, close tx of protocol stack. 2) wait rcb, ppe, mac to clean. 3) adjust link 4) open rx of chip, open tx of protocol stack. 2, Hisilicon hip05 and hip06 board network card do not support 1000M half configuration. Driver can not config gmac as 1000M half.
