Maxim Mikityanskiy 1b8a10bbfe net/mlx5e: Permit XDP with non-linear legacy RQ 
Now that legacy RQ implements XDP in the non-linear mode, stop blocking
this configuration. Allow non-linear mode only for programs aware of
multi buffer.

XDP performance with linear mode RQ hasn't changed.

Baseline (MTU 1500, TX MPWQE, legacy RQ, single core):
 60-byte packets, XDP_DROP: 11.25 Mpps
 60-byte packets, XDP_TX: 9.0 Mpps
 60-byte packets, XDP_PASS: 668 kpps

Multi buffer (MTU 9000, TX MPWQE, legacy RQ, single core):
 60-byte packets, XDP_DROP: 10.1 Mpps
 60-byte packets, XDP_TX: 6.6 Mpps
 60-byte packets, XDP_PASS: 658 kpps
 8900-byte packets, XDP_DROP: 769 kpps (100% of sent packets)
 8900-byte packets, XDP_TX: 674 kpps (100% of sent packets)
 8900-byte packets, XDP_PASS: 637 kpps

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.
