[dpdk-stable] patch 'net/ixgbe: fix link status synchronization on BSD' has been queued to stable release 19.11.3

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/21/20. 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.

Luca Boccassi

Subject: [PATCH] net/ixgbe: fix link status synchronization on BSD

[ upstream commit 0012111a3d879b0b0e27d14a841e2a729545727d ]

DPDK does not implement interrupt mechanism on BSD,
so force NIC status synchronization.

Fixes: dc66e5fd01b9 ("net/ixgbe: improve link state check on VF")
