patch 'net/txgbe: fix driver load bit to inform firmware' has been queued to stable release 23.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/10/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=a6f62c575b8a25b727da665ee8659d31e8f1fb9c

Thanks.

Subject: [PATCH] net/txgbe: fix driver load bit to inform firmware
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 0a8f064bbc2cf4978857eae84e86c6b2c9e65feb ]

Drv_load bit will be reset to default 0 after hardware LAN reset,
reconfigure it to inform firmware that driver is loaded. And set it to 0
when device is closed.

Fixes: b1f596677d8e ("net/txgbe: support device start")
