After previous modifications, the offloads are no longer called one by one, the pi is calculated and the wqe is cleared on between of TLS and IPSEC offloads, which doesn't quite fit mlx5e_accel_handle_tx's purpose. This patch splits mlx5e_accel_handle_tx into two functions that correspond to two logical phases of running offloads: 1. Before fetching a WQE. Here runs the code that can post WQEs on its own, before the main WQE is fetched. It's the main part of TLS offload. 2. After fetching a WQE. Here runs the code that updates the WQE's fields, but can't post other WQEs any more. It's a minor part of TLS offload that sets the tisn field in the cseg, and eseg-based offloads (currently IPSEC, and later patches will move GENEVE and checksum offloads there, too). It allows to make mlx5e_xmit take care of all actions needed to transmit a packet in the right order, improve the structure of the code and reduce unnecessary operations. The structure will be further improved in the following patches (all eseg-based offloads will be moved to a single place, and reserving space for the main WQE will happen between phase 1 and phase 2 of offloads to eliminate unneeded data movements).

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.
