Borislav Petkov 0276bd3a94 IB/mlx5: Fix undefined behavior due to shift overflowing the constant
Fix:

  drivers/infiniband/hw/mlx5/main.c: In function ‘translate_eth_legacy_proto_oper’:
  drivers/infiniband/hw/mlx5/main.c:370:2: error: case label does not reduce to an integer constant
    case MLX5E_PROT_MASK(MLX5E_50GBASE_KR2):
    ^~~~

See https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@zn.tnic for the gory
details as to why it triggers with older gccs only.

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.
