Add failed_counter to i21x_doublecheck(). There is possibility that
loop will never end.
With this patch the loop will stop after maximum 3 retries
to write to MTA_REGISTER

Add new function which checks MTA_REGISTER if its filled correctly.
If not then writes again to same register.
There is possibility that i210 and i211 could not accept
MTA_REGISTER settings, specially when you add and remove
many of multicast addresses in short time.
Without this patch there is possibility that multicast settings will be
not always set correctly in hardware.

This takes care of all of the trivial W=1 fixes in the Intel
Ethernet drivers, which allows developers and maintainers to
build more of the networking tree with more complete warning
checks.
There are three classes of kdoc warnings fixed:
- cannot understand function prototype: 'x'
- Excess function parameter 'x' description in 'y'
- Function parameter or member 'x' not described in 'y'
All of the changes were trivial comment updates on
function headers.
Inspired by Lee Jones' series of wireless work to do the same.
Compile tested only, and passes simple test of

This function always return 0 now, we can make it return void to
simplify the code. This fixes the following coccicheck warning:

After many years of having a ~30 line copyright and license header to our
source files, we are finally able to reduce that to one line with the
advent of the SPDX identifier.
Also caught a few files missing the SPDX license identifier, so fixed
them up.

For bitshifts, we should make use of the BIT macro when possible, and
ensure that other bitshifts are marked as unsigned. This helps prevent
signed bitshift errors, and ensures similar style.
Make use of GENMASK and the unsigned postfix where BIT() isn't
appropriate.

This change makes it so that we can merge the configuration of the VLVF
registers into the setting of the VFTA register. By doing this we simplify
the logic and make use of similar functionality that we have already added
for ixgbe making it easier to maintain both drivers.

This patch addresses the changes needed to make LEDs work properly with
negative logic. This implementation uses LED Invert bit to reverse the
logic issue that occurred when LEDs are driven by cathode. Keep LEDs
blinking for SerDes devices. Also made changes to magic number and the
for loop to reduce number of shifts.
