[ Upstream commit ffffd2454a7a1bc9f7242b12c4cc0b05c12692b4 ]
Recent sfc NICs are TSO capable for some tunnel protocols. However, it
was not working properly because the feature was not advertised in
hw_enc_features, but in hw_features only.
Setting up a GENEVE tunnel and using iperf3 to send IPv4 and IPv6 traffic
to the tunnel show, with tcpdump, that the IPv4 packets still had ~64k
size but the IPv6 ones had only ~1500 bytes (they had been segmented by
software, not offloaded). With this patch segmentation is offloaded as
expected and the traffic is correctly received at the other end.
Fixes: 24b2c3751aa3 ("sfc: advertise encapsulated offloads on EF10")

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.
