> individual tables.
> In patch #1, introduce a structure for keeping per-chip immutable and
> default values.
> In patch #2, structures for keeping current values of SBPM and SBPR
> (pool configuration and port-pool quota) are allocated dynamically to
> support varying pool counts.
> In patches #3 to #7, uses of individual shared buffer configuration
> tables are migrated from global definitions to fields in struct
> mlxsw_sp_sb_vals, which was introduced above.
> Up until this point, the actual configuration is still the one suitable
> for Spectrum-1. In patch #8 Spectrum-2 configuration is added.
> In patch #9, port headroom configuration is changed to take into account
> current recommended value for a 100-Gbps port, and the split factor.
> In patch #10, requests for overlarge headroom are rejected. This avoids
> potential chip freeze should such overlarge requests be made.

Series applied, thanks.
