net: hns3: add support to query and set lane number by ethtool When serdes lane support setting 25Gb/s or 50Gb/s speed and user wants to set port speed as 50Gb/s, it can be setted as one 50Gb/s serdes lane or two 25Gb/s serdes lanes.

net: hns3: fix phy can not link up when autoneg off and reset Currently, function hclge_mdio_read() will return 0 if during reset(the cmd state will be set to disable). If use general phy driver, the phy_state_machine() will update phy speed every second in function genphy_read_status_fixed() when PHY is set to autoneg off, no matter of link down or link up. If phy driver happens to read BMCR register during reset, phy speed will be updated to 10Mpbs as BMCR register value is 0. So it may call phy can not link up if previous speed is not 10Mpbs. To fix this problem, function hclge_mdio_read() should return -EBUSY if the cmd state is disable. So does function hclge_mdio_write().

net: hns3: refactor hclge_cmd_send with new hclge_comm_cmd_send API This patch firstly uses new hardware description struct hclge_comm_hw as child member of hclge_hw and deletes the original child memebers of hclge_hw. All the hclge_hw variables used in PF module is modified according to the new hclge_hw. Secondly hclge_cmd_send is refactored to use hclge_comm_cmd_send APIs.
