====================
mlxsw: Add Spectrum-4 support

This patchset adds Spectrum-4 support in mlxsw. It builds on top of a
previous patchset merged in commit 10184da9 ("Merge branch
'mlxsw-Spectrum-4-prep'") and makes two additional changes before adding
Spectrum-4 support.

Patchset overview:

Patches #1-#2 add a few Spectrum-4 specific variants of existing ACL
keys. The new variants are needed because the size of certain key
elements (e.g., local port) was increased in Spectrum-4.

Patches #3-#6 are preparations.

Patch #7 implements the Spectrum-4 variant of the Bloom filter hash
function. The Bloom filter is used to optimize ACL lookups by
potentially skipping certain lookups if they are guaranteed not to
match. See additional info in merge commit ae6750e0 ("Merge branch
'mlxsw-spectrum_acl-Add-Bloom-filter-support'").

Patch #8 finally adds Spectrum-4 support.
