The buffer length field in the ena rx descriptor is 16 bit, and the current driver passes a full page in each ena rx descriptor. When PAGE_SIZE equals 64kB or more, the buffer length field becomes zero. To solve this issue, limit the ena Rx descriptor to use 16kB even when allocating 64kB kernel pages. This change would not impact ena device functionality, as 16kB is still larger than maximum MTU. Signed-off-by: Netanel Belgazal <netanel@amazon.com> Signed-off-by: David S.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
