patch 'net/axgbe: disable interrupts during device removal' has been queued to stable release 21.11.8

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/24. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/a14247758ae4d076545ec3006060d274f26d3c6a

Thanks.

Kevin

Subject: [PATCH] net/axgbe: disable interrupts during device removal

[ upstream commit 7b7288b08760204139085174ba00a2863dfdbbec ]

Hardware interrupts are enabled during the init, however, they are not
disabled during close.

Disable all hardware interrupts during close operation to avoid any
issues.

Fixes: 9e890103267e ("net/axgbe: add Rx/Tx setup")
