Without the previous commit, "modprobe test_bpf" will have the following errors: ... [ 98.149165] ------------[ cut here ]------------ [ 98.159362] kernel BUG at net/core/skbuff.c:3667! [ 98.169756] invalid opcode: 0000 [#1] SMP PTI [ 98.179370] Modules linked in: [ 98.179371] test_bpf(+) ... which triggers the bug the previous commit intends to fix. The skbs are constructed to mimic what mlx5 may generate. The packet size/header may not mimic real cases in production. But the processing flow is similar.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
