patch 'bpf: disable on 32-bit x86' has been queued to stable release 22.11.6

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/24. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/1f65019c2d7ff5396cb18a4ceeba231c6607b881

Thanks.

Luca Boccassi

Subject: [PATCH] bpf: disable on 32-bit x86

[ upstream commit 4edbcc7b5313949083f7694847342b1a45659d6b ]

As per Intel, this is not supported, and the librte-bpf test fails on
32bit x86 kernels, so disable the library and the pmd.
