Maxim Mikityanskiy 7a0b297480 net/mlx5e: Block LRO if firmware asks for tunneled LRO 
[ Upstream commit 26ab7b3845 ]

This commit does a cleanup in LRO configuration.

LRO is a parameter of an RQ, but its state is changed by modifying a TIR
related to the RQ.

The current status: LRO for tunneled packets is not supported in the
driver, inner TIRs may enable LRO on creation, but LRO status of inner
TIRs isn't changed in mlx5e_modify_tirs_lro(). This is inconsistent, but
as long as the firmware doesn't declare support for tunneled LRO, it
works, because the same RQs are shared between the inner and outer TIRs.

This commit does two fixes:

1. If the firmware has the tunneled LRO capability, LRO is blocked
altogether, because it's not possible to block it for inner TIRs only,
when the same RQs are shared between inner and outer TIRs, and the
driver won't be able to handle tunneled LRO traffic.

2. mlx5e_modify_tirs_lro() is patched to modify LRO state for all TIRs,
including inner ones, because all TIRs related to an RQ should agree on
their LRO state.

README 

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.
