This model was added as INTEL_PANTHERCOVE_X (based on the name of the
core) with a comment that the platform name is Diamond Rapids. It was
also placed at the end of the file in a new section for family 19
processors.
This is different from previous naming as Andrew Cooper noted.
PeterZ agreed and posted a patch[1] to fix the name and move it in
sequence with other Xeon servers. But without a commit description or
sign-off the patch wasn't ever applied.
Patch updated to cover one additional use of the #define by turbostat
and to change the "Family 6" comment to also list 18 and 19 since new
models in these families are mixed in with family 6.

Update the WQE metadata assignment to avoid overriding existing
metadata when setting the sysport timestamp ID. Since timestamp IDs are
limited to 256 values, they use only the lower 8 bits of the metadata
field.
To avoid conflicts, move IPsec and MACsec metadata ID to bits 8 and 9,
and shift the MACsec fs_id accordingly. This ensures safe coexistence
of timestamping and offload features that use the same metadata field.

Introduce MLX5_ETH_WQE_FT_META_SHIFT as a shared base offset for
features that use the lower 8 bits of the WQE flow_table_metadata
field, currently used for timestamping, IPsec, and MACsec.
Define MLX5_ETH_WQE_FT_META_MACSEC_FS_ID_MASK so that fs_id occupies
bits 2–5, making it clear that fs_id occupies bits in the metadata.
Set MLX5_ETH_WQE_FT_META_MACSEC_MASK as the OR of the MACsec flag and
MLX5_ETH_WQE_FT_META_MACSEC_FS_ID_MASK, corresponding to the original
0x3E mask.
Update the fs_id macro to right-shift the MACsec flag by
MLX5_ETH_WQE_FT_META_SHIFT and update the RoCE modify-header action to
use it.
Introduce the helper macro MLX5_MACSEC_TX_METADATA(fs_id) to compose
the full shifted MACsec metadata value.
These changes make it explicit exactly which metadata bits carry MACsec
information, simplifying future feature exclusions when multiple
features share the WQE flowtable metadata.
In addition, drop the incorrect “RX flow steering” comment, since this
applies to TX flow steering.

Common TIF bits do not have to be defined by every architecture. They can
be defined in a generic header.
That allows adding generic TIF bits without chasing a gazillion of
architecture headers, which is again a unjustified burden on anyone who
works on generic infrastructure as it always needs a boat load of work to
keep existing architecture code working when adding new stuff.
While it is not as horrible as the ignorance of the generic entry
infrastructure, it is a welcome mechanism to make architecture people
rethink their approach of just leaching generic improvements into
architecture code and thereby making it accumulatingly harder to maintain
and improve generic code. It's about time that this changes.
Provide the infrastructure and split the TIF space in half, 16 generic and
16 architecture specific bits.
This could probably be extended by TIF_SINGLESTEP and BLOCKSTEP, but those
are only used in architecture specific code. So leave them alone for now.
