[ Upstream commit413f142cc0] Ingress large send packets are identified by either: The IBMVETH_RXQ_LRG_PKT flag in the receive buffer or with a -1 placed in the ip header checksum. The method used depends on firmware version. Frame geometry and sufficient header validation is performed by the hypervisor eliminating the need for further header checks here.

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.
