[dpdk-stable] patch 'net/i40e: fix send admin queue command before init' has been queued to stable release 18.08.1

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 18.08.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/27/18. 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. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Kevin Traynor

Subject: [PATCH] net/i40e: fix send admin queue command before init

[ upstream commit 0a1b657838c2c0546ebc6469ed2840c5a9a796f4 ]

We should not issue Admin Queue command before Admin Queue is initialized.
But this happened in i40e_hw_init and i40e_filter_input_set_init.

The patch fixes the issue by proper reordering.

Fixes: b6a0ec418274 ("i40e: use AQ for Rx control register read/write")
