[dpdk-stable] patch 'net/fm10k: fix internal switch initial status' has been queued to LTS release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/19. 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.

Thanks.

Kevin Traynor

Subject: [PATCH] net/fm10k: fix internal switch initial status

[ upstream commit 04018a4552e630a2c019bade0c6b5f822aded0c1 ]

sm_down is a boolean in order to check if the internal switch of the
fm10k is up or down. This variable is configured though an interrupt by
fm10k_dev_interrupt_handler_pf.

If sm_down is uninitialized, we are not sure of its value at the first
bring up. For example, if FM10K_EICR_SWITCHREADY is raised, the PMD will
try to reconfigure the switch, but it does not make sense, as it's the
first startup.

The sm_down implementation has been introduced
commit 6c9f37245583 ("net/fm10k: support switch restart on PF").

Fixes: 6f22f2f67268 ("net/fm10k: redefine link status semantics")
