tools: include: Add ethtool_drvinfo definition to UAPI header

Instead of copying the whole header in, just add the struct definitions
we need for now. In the future it can be synced as a copy of in-tree
header if required.

+/**
+ * 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; may be an empty string
+ * @erom_version: Expansion ROM version string; 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).
+ *
+ * Drivers should set at most @driver, @version, @fw_version and
+ * @bus_info in their get_drvinfo() implementation.  The ethtool
+ * core fills in the other fields using other driver operations.
