[ Upstream commit4e81c0b3fa] When user-space sets the OVS_UFID_F_OMIT_* flags, and the relevant flow has no UFID, we can exceed the computed size, as ovs_nla_put_identifier() will always dump an OVS_FLOW_ATTR_KEY attribute. Take the above in account when computing the flow command message size. Fixes:74ed7ab926("openvswitch: Add support for unique flow IDs.")

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.
