From: Jiri Pirko <j...@mellanox.com> Arkadi says:
Many of the ASIC's internal resources are limited and are shared between several hardware procedures. For example, unified hash-based memory can be used for many lookup purposes, like FDB and LPM. In many cases the user can provide a partitioning scheme for such a resource in order to perform fine tuning for his application. In many cases after setting the partitioning of the resource driver reload is needed. This patchset add support for hot reset of the driver. The proposed interface will provide the user the ability to understand the limitations of the hardware, and receive notification regarding its occupancy. Furthermore, monitoring the resource occupancy can be done in real-time and can be useful in many cases.
