[ Upstream commit 6215afcb9a ]
A make W=1 build complains that:
net/sched/cls_flower.c:214:20: warning: cast from restricted __be16
net/sched/cls_flower.c:214:20: warning: incorrect type in argument 1 (different base types)
net/sched/cls_flower.c:214:20: expected unsigned short [usertype] val
net/sched/cls_flower.c:214:20: got restricted __be16 [usertype] dst
This is because we use htons on struct flow_dissector_key_ports members
src and dst, which are defined as __be16, so they are already in network
byte order, not host. The byte swap function for the other direction
should have been used.
Because htons and ntohs do the same thing (either both swap, or none
does), this change has no functional effect except to silence the
warnings.

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.
