TLS offload may write a 32-bit field (tisn) to the cseg of the WQE. To do that, it receives pi and wqe pointers. As TLS offload may also send additional WQEs, it has to update pi and wqe, and in many cases it even doesn't use pi calculated before and wqe zeroed before and does it itself. Also, mlx5e_sq_xmit has to copy the whole cseg if it goes to the mlx5e_fill_sq_frag_edge flow. This all is not efficient. It's more efficient to do the following: 1. Just return tisn from TLS offload and make the caller fill it in a more appropriate place. 2. Calculate pi and clear wqe after calling TLS offload. 3. If TLS offload has to send WQEs, calculate pi and clear wqe just before that. It's already done in all places anyway, so this commit allows to remove some redundant memsets and calls. Copying of cseg will be eliminated in one of the following commits, and all other stuff is done here.

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.
