Now that we have bpf_flow_dissect which can work on raw data, use it when doing BPF_PROG_TEST_RUN for flow dissector. Simplifies bpf_prog_test_run_flow_dissector and allows us to test no-skb mode. Note, that previously, with bpf_flow_dissect_skb we used to call eth_type_trans which pulled L2 (ETH_HLEN) header and we explicitly called skb_reset_network_header. That means flow_keys->nhoff would be initialized to 0 (skb_network_offset) in init_flow_keys. Now we call bpf_flow_dissect with nhoff set to ETH_HLEN and need to undo it once the dissection is done to preserve the existing behavior.

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.
