@brief Misc IO function of Etherent driver

@param[in] hdl: handle of Ethernet driver @param[in] cmd: IO control command @param[in, out] data: address of data for set command or address where to store the data when used with get command

@return - ESP_OK: process io command successfully - ESP_ERR_INVALID_ARG: process io command failed because of some invalid argument - ESP_FAIL: process io command failed because some other error occurred - ESP_ERR_NOT_SUPPORTED: requested feature is not supported

The following common IO control commands are supported: @li @c ETH_CMD_S_MAC_ADDR sets Ethernet interface MAC address. @c data argument is pointer to MAC address buffer with expected size of 6 bytes. @li @c ETH_CMD_G_MAC_ADDR gets Ethernet interface MAC address. @c data argument is pointer to a buffer to which MAC address is to be copied. The buffer size must be at least 6 bytes. @li @c ETH_CMD_S_PHY_ADDR sets PHY address in range of <0-31>. @c data argument is pointer to memory of uint32_t datatype from where the configuration option is read. @li @c ETH_CMD_G_PHY_ADDR gets PHY address. @c data argument is pointer to memory of uint32_t datatype to which the PHY address is to be stored. @li @c ETH_CMD_S_AUTONEGO enables or disables Ethernet link speed and duplex mode autonegotiation. @c data argument is pointer to memory of bool datatype from which the configuration option is read. Preconditions: Ethernet driver needs to be stopped. @li @c ETH_CMD_G_AUTONEGO gets current configuration of the Ethernet link speed and duplex mode autonegotiation. @c data argument is pointer to memory of bool datatype to which the current configuration is to be stored. @li @c ETH_CMD_S_SPEED sets the Ethernet link speed. @c data argument is pointer to memory of eth_speed_t datatype from which the configuration option is read. Preconditions: Ethernet driver needs to be stopped and auto-negotiation disabled. @li @c ETH_CMD_G_SPEED gets current Ethernet link speed. @c data argument is pointer to memory of eth_speed_t datatype to which the speed is to be stored. @li @c ETH_CMD_S_PROMISCUOUS sets/resets Ethernet interface promiscuous mode. @c data argument is pointer to memory of bool datatype from which the configuration option is read. @li @c ETH_CMD_S_FLOW_CTRL sets/resets Ethernet interface flow control. @c data argument is pointer to memory of bool datatype from which the configuration option is read. @li @c ETH_CMD_S_DUPLEX_MODE sets the Ethernet duplex mode. @c data argument is pointer to memory of eth_duplex_t datatype from which the configuration option is read. Preconditions: Ethernet driver needs to be stopped and auto-negotiation disabled. @li @c ETH_CMD_G_DUPLEX_MODE gets current Ethernet link duplex mode. @c data argument is pointer to memory of eth_duplex_t datatype to which the duplex mode is to be stored. @li @c ETH_CMD_S_PHY_LOOPBACK sets/resets PHY to/from loopback mode. @c data argument is pointer to memory of bool datatype from which the configuration option is read.

@li Note that additional control commands may be available for specific MAC or PHY chips. Please consult specific MAC or PHY documentation or driver code.
