62 * @fw_version: Firmware version string; may be an empty string
63 * @erom_version: Expansion ROM version string; may be an empty string
64 * @bus_info: Device bus address.  This should match the dev_name()

66 *	an empty string.
67 * @reserved2: Reserved for future use; see the note on reserved space.
68 * @n_priv_flags: Number of flags valid for %ETHTOOL_GPFLAGS and
69 *	%ETHTOOL_SPFLAGS commands; also the number of strings in the
70 *	%ETH_SS_PRIV_FLAGS set
71 * @n_stats: Number of u64 statistics returned by the %ETHTOOL_GSTATS
72 *	command; also the number of strings in the %ETH_SS_STATS set

77 * @regdump_len: Size of register dump returned by the %ETHTOOL_GREGS
78 *	command, in bytes

80 * Users can use the %ETHTOOL_GSSET_INFO command to get the number of
81 * strings in any string set (from Linux 2.6.34).
82 *
83 * Drivers should set at most @driver, @version, @fw_version and
84 * @bus_info in their get_drvinfo() implementation.  The ethtool
85 * core fills in the other fields using other driver operations.
