Note that inet_aton() allows the address to be specified as a single
32-bit number in the same formats as strtoull(), so this is backward-
compatible.

Many NICs use an indirection table to map an RX flow hash value to one
of an arbitrary number of queues (not necessarily a power of 2). It
can be useful to remove some queues from this indirection table so
that they are only used for flows that are specifically filtered
there. It may also be useful to weight the mapping to account for
user processes with the same CPU-affinity as the RX interrupts.

Define an argument type CMDL_FLAG, which can be used to set and
clear flags. For each setting that can be modified in this way,
the flags to be set and cleared are accumulated in two variables.
Add support for CMDL_FLAGS parse_generic_cmdline().
Add utility function print_flags().

The arguments for RX n-tuple traffic direction are filled into
structure fields of varying size, some of which are in big-endian
rather than native byte order. Currently parse_generic_cmdline()
only supports 32-bit integers in native byte order, so this does
not work correctly.
Replace CMDL_INT and CMDL_UINT with the more explicit CMDL_S32 and
CMDL_U32. Add CMDL_U16 and CMDL_U64 for narrower and wider integers,
and CMDL_BE16 and CMDL_BE32 for big-endian unsigned integers. Use
them for RX n-tuple argument parsing.

A recent change to how int's were being parsed from the command
line had them being read in with an unsigned int string operator.
This didn't allow signed numbers from being read in correctly.
This patch adds a get_uint() routine, and fixes the get_int()
routine to read in signed values.

This also fixes the bug that the usage message displays %%[dx] instead
of %[dx]. This does not fix the fact that the usage message says
%[dx] in some places and 'N' in others. Maybe it should use %d where
only base-10 is accepted, %x where only base-16 is, and N where either
is acceptable.

This patch adds a new "-f" option to the ethtool utility to flash a
firmware image specified by a file, to a network device. The filename
is passed to the network driver which will flash the image on the
chip using the request_firmware path.
The region "on the chip" to be flashed can be specified by an option.
It is up to the device driver to enumerate the region number passed
by ethtool, to the region to be flashed.
The default behavior is to flash all the regions on the chip.
Usage:
ethtool -f <interface name> <filename of firmware image>
ethtool -f <interface name> <filename of firmware image> [ REGION-NUMBER-TO-FLASH ]

The speed and speed_hi fields of struct ethtool_cmd together represent
a value in units of Mbit/s. The valid speed settings are hardware-
dependent and should be checked by the driver. Remove our validation
and allow arbitrary positive values. Continue to report 0 and -1 as
"Unknown!" since some drivers will report these invalid values when
the link is down.
