Jan Sokolowski c685c69fba ixgbe: don't do any AF_XDP zero-copy transmit if netif is not OK
An issue has been found while testing zero-copy XDP that
causes a reset to be triggered. As it takes some time to
turn the carrier on after setting zc, and we already
start trying to transmit some packets, watchdog considers
this as an erroneous state and triggers a reset.

Don't do any work if netif carrier is not OK.

Fixes: 8221c5eba8 (ixgbe: add AF_XDP zero-copy Tx support)

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.
