There are several uses of hw_dbg in the code, producing no output. This
patch implements it using dev_debug.
Initially the intention was to implement it using netdev_dbg, analogously
to what is done in ixgbe for instance. That approach was avoided due to
some early usages of hw_dbg, like i40e_pf_reset, before the VSI structure
initialization causing NULL pointer dereference during the driver probe if
the debug messages were turned on as soon as the module is probed.
v2:
- Use dev_dbg instead of pr_debug, and take advantage of dev_name
instead of crafting pretty much the same device name locally as suggested
by Jakub Kicinski.

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.

Looking over the code for FCoE it looks like the Rx path has been broken at
least since the last major Rx refactor almost a year ago. It seems like
FCoE isn't supported for any of the Fortville/Fortpark hardware so there
isn't much point in carrying the code around, especially if it is broken
and untested.

Currently i40e_bus_info has PCI device and function info only and log
messages print device number as bus number. Added field to provide bus
number info and modified log statements to print bus, device and
function information.

'struct i40e_dma_mem' defined with 'packed' directive causing kernel
unaligned errors on sparc.
e.g.

1.6.16-k
i40e: Copyright (c) 2013 - 2014 Intel Corporation.

This can be fixed with get_unaligned/put_unaligned(). However no
reference in driver shows that 'struct i40e_dma_mem' directly shoved
into NIC hardware. But instead fields of the struct are being read and
used for hardware. Therefore, __packed is unnecessary for 'struct
i40e_dma_mem'.
In addition, although 'struct i40e_virt_mem' doesn't cause any
unaligned access, keeping it packed is unnecessary as well because
of aforementioned reason.
This change make 'struct i40e_dma_mem' and 'struct i40e_virt_mem'
unpacked.

Adds FCoE config option I40E_FCOE, so that FCoE can be enabled
as needed but otherwise have it disabled by default.
This also eliminate multiple FCoE config checks, instead now just
one config check for CONFIG_I40E_FCOE.
The I40E FCoE was added with 3.17 kernel and therefore this patch
shall be applied to stable 3.17 kernel also.

Adds FCoE specific code to existing i40e core driver to:-
1. have separate FCoE VSI with additional FCoE queues pairs.
2. have FCoE related hash defines.
3. have additional FCoE related stats code.
4. export and then re-use existing functions required by FCoE build.
