net: hns: add the code for cleaning pkt in chip
[ Upstream commit 31fabbee8f5c658c3fa1603c66e9e4f51ea8c2c6 ]
If there are packets in hardware when changing the speed
or duplex, it may cause hardware hang up.
This patch 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 patch 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.
