Hi,

Find detailed description by Moshe below.

This series adds driver support for the VHCA_ID page management mode.
When firmware and driver support this mode, ICM (Interconnect Context
Memory) page management uses the device vhca_id as the function
identifier in MANAGE_PAGES, QUERY_PAGES, and page request events instead
of the legacy function_id + ec_function pair.

Background
Firmware can operate page management in two modes:
FUNC_ID mode (current): Function identity is (function_id, ec_function).
This remains the default and is used for boot pages and when the new
mode capability is not set.
VHCA_ID mode (new): Function identity is vhca_id only; ec_function is
ignored. This aligns page management with the vhca_id-based model used
by other firmware commands and simplifies identification on SmartNIC and
multi-function setups.

---

V2:
- Cache vhca_id to type mapping to provide lockless lookup.
- Store the resolved type on each fw_page at allocation time so reclaim
  and release paths read it directly without any lookup.
- Reorder erase old key and insert new key on migrate function.
- Fixed comment on mlx5_satisfy_startup_pages.
