When the TLS logic finds a tcp seq match for a kTLS RX resync request, it calls the driver callback function mlx5e_ktls_resync() to handle it and communicate it to the device. Errors might occur during mlx5e_ktls_resync(), however, they are not reported to the stack. Moreover, there is no error handling in the stack for these errors. In this patch, the driver obtains responsibility on errors handling, adding queue and retry mechanisms to these resyncs. We maintain a linked list of resync matches, and try posting them to the async ICOSQ in the NAPI context. Only possible failure that demands driver handling is ICOSQ being full. By relying on the NAPI mechanism, we make sure that the entries in list will be handled when ICOSQ completions arrive and make some room available.

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.
