Subject: [patch net-next RFC 0/7] Add support for resource abstraction

From: Jiri Pirko <jiri@...lanox.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.
