====================
net: hns: fix some bugs about speed and duplex change

If there are packets in hardware when changing the spped
or duplex, it may cause hardware hang up.

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.
====================
