The CX7 cards which support IPsec packet offload use 32 bits to configure soft and hard packet limits. This is not enough as the software part using 64 bits. The needed functionality of supporting 64 bits is implemented through mlx5 abstraction layer, which will ensure that HW is reconfigured on-demand every 2^31 packets. To simulate the 64 bit IPsec soft/hard limits, we divide the soft/hard limits to multiple interrupts (rounds). Each round counts 2^31 packets. Once the counter is less than or equal to 2^31, the soft event is raised and software sets the bit 31 of the counter and decrement the round counter.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
