commit63e4b45c82upstream. When rx_buf is allocated we need to account for IPHETH_IP_ALIGN, which reduces the usable size by 2 bytes. Otherwise we have 1512 bytes usable instead of 1514, and if we receive more than 1512 bytes, ipheth_rcvbulk_callback is called with status -EOVERFLOW, after which the driver malfunctiones and all communication stops.

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.
