Inserting or deleting a rule is done by RDMA read/write operation to SW
ICM device memory. This file provides the support for executing these
operations. It includes allocating the needed resources and providing an
API for writing steering entries to the memory.

ICM device memory is used for writing steering rules (STEs) to the NIC.
An ICM memory pool allocator was implemented to manage the required
memory. The pool consists of buckets, a bucket per chunk size.
Once a bucket is empty we will cut a row of memory from the latest
allocated MR, if the MR size is not sufficient we will allocate a new MR.
HW design requires that chunks memory address should be aligned to the
chunk size, this is the reason for managing the MR with row size that
insures memory alignment.
Current design is greedy in memory but provides quick allocation times
in steady state.

This fatal reset differs from the non-fatal reset at the beginning
stages. From the BNXT_FW_RESET_STATE_ENABLE_DEV state onwards where
the firmware is coming out of reset, it is practically identical to the
