In commit 26a4676faa ("arm64: mm: define NET_IP_ALIGN to 0"),
AVE controller affects this modification because the controller forces
to ignore lower 2bits of buffer start address, and make 2-byte headroom,
that is, data reception starts from (buffer + 2).
This patch defines AVE_FRAME_HEADROOM macro as hardware-specific value,
and replaces NET_IP_ALIGN with it.

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.
