Prior to this patch the maximal value for max WQEBBs (WQE Basic Blocks, where WQE is a Work Queue Element) on the TX side was assumed to be 16 (fixed value). All firmware versions till today comply to this. In order to be more flexible and resilient, read from FW the corresponding: max_wqe_sz_sq. This value describes the maximum WQE size given in bytes, thus max WQEBBs is given by the division in WQEBB's byte size. The driver uses the top between 16 and the division result. This ensures synchronization between driver and firmware and avoids unexpected behavior. Store this value on the different SQs (Send Queues) for easy access.

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.
