Based on the original work from Arnd Bergmann.
When XFRM_ALGO is not enabled, the new ixgbe IPsec code produces a
link error:
drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.o: In function `ixgbe_ipsec_vf_add_sa':
ixgbe_ipsec.c:(.text+0x1266): undefined reference to `xfrm_aead_get_byname'
Simply selecting XFRM_ALGO from here causes circular dependencies, so
to fix it, we probably want this slightly more complex solution that is
similar to what other drivers with XFRM offload do:
A separate Kconfig symbol now controls whether we include the IPsec
offload code. To keep the old behavior, this is left as 'default y'. The
dependency in XFRM_OFFLOAD still causes a circular dependency but is
not actually needed because this symbol is not user visible, so removing
that dependency on top makes it all work.

Add the IPsec offload support code. This is based off of the similar
code in ixgbe, but instead of writing the SA registers, the VF asks
the PF to setup the offload by sending the offload information to the
PF via the standard mailbox.

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.

Moves the Intel wired LAN drivers into drivers/net/ethernet/intel/ and
the necessary Kconfig and Makefile changes.
