This patchset adds Spectrum-4 support in mlxsw. It builds on top of a previous patchset merged in commit 10184da91666 ("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 ae6750e0a5ef ("Merge branch 'mlxsw-spectrum_acl-Add-Bloom-filter-support'"). Patch #8 finally adds Spectrum-4 support.
