/**
 * struct ethtool_drvinfo - general driver and device information
 * @cmd: Command number = %ETHTOOL_GDRVINFO
 * @driver: Driver short name.  This should normally match the name
 *	in its bus driver structure (e.g. pci_driver::name).  Must
 *	not be an empty string.
 * @version: Driver version string; may be an empty string
 * @fw_version: Firmware version string; driver defined; may be an
 *	empty string
 * @erom_version: Expansion ROM version string; driver defined; may be
 *	an empty string
 * @bus_info: Device bus address.  This should match the dev_name()
 *	string for the underlying bus device, if there is one.  May be
 *	an empty string.
 * @reserved2: Reserved for future use; see the note on reserved space.
 * @n_priv_flags: Number of flags valid for %ETHTOOL_GPFLAGS and
 *	%ETHTOOL_SPFLAGS commands; also the number of strings in the
 *	%ETH_SS_PRIV_FLAGS set
 * @n_stats: Number of u64 statistics returned by the %ETHTOOL_GSTATS
 *	command; also the number of strings in the %ETH_SS_STATS set
 * @testinfo_len: Number of results returned by the %ETHTOOL_TEST
 *	command; also the number of strings in the %ETH_SS_TEST set
 * @eedump_len: Size of EEPROM accessible through the %ETHTOOL_GEEPROM
 *	and %ETHTOOL_SEEPROM commands, in bytes
 * @regdump_len: Size of register dump returned by the %ETHTOOL_GREGS
 *	command, in bytes
 *
 * Users can use the %ETHTOOL_GSSET_INFO command to get the number of
 * strings in any string set (from Linux 2.6.34).
