Hi,

FYI, your patch has been queued to stable release 20.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/19/22. 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/c93d1201cc433a2666ac8a1c37d7172c666aedb7

Thanks.

Luca Boccassi

Subject: [PATCH] doc: fix missing note on UIO module in Linux guide

[ upstream commit b421909ce7c42109ebb3236275793b1c7fd3394e ]

The docs on binding drivers was updated as part of the removal of the
igb_uio module from the main DPDK repo. As part of that update, a note
about uio_pci_generic requiring legacy interrupts was removed, but
should have been kept.

Fixes: 56bb5841fd06 ("kernel/linux: remove igb_uio")
