net: hns: fix to intimate the link-status change by adding LF/RF method In current scenario, when the interface is disabled we reset the XGMAC RX/TX functionality. This operation does not affects the PHY layer/SFP and which appears UP to the remote end(this behaviour is unlike GMAC). The result is remote end keeps on sending the packets which gets partly processed by XMAC and dropped. Since these are partly processed these appears as errored packets in the packet counter statistics. This patch fixes this behaviour and adds local-fault and remote-fault functionality which can be used to intimate the remote peer whenever the state of the interface changes. This patch also removes the existing hns_dsaf_xge_core_srst_by_port function which was being used to reset the RX/TX functionality at XGE Core.
