This patch adds support for matching fragmented packets in tc flower filters. Previously, commit93a8540aac("cxgb4: flower: validate control flags") added a check using flow_rule_match_has_control_flags() to reject any rules with control flags, as the driver did not support fragmentation at that time. Now, with this patch, support for FLOW_DIS_IS_FRAGMENT is added: - The driver checks for control flags using flow_rule_is_supp_control_flags(), as recommended in commitd11e631194("flow_offload: add control flag checking helpers"). - If the fragmentation flag is present, the driver sets `fs->val.frag` and `fs->mask.frag` accordingly in the filter specification. Since fragmentation is now supported, the earlier check that rejected all control flags (flow_rule_match_has_control_flags()) has been removed.

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 reStructuredText 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.
