[dpdk-stable] patch 'net/i40e: remove redundant reset of queue number' has been queued to stable release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable 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 12/18/18. 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. 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/i40e: remove redundant reset of queue number

[ upstream commit ef8b7c505f10897621c0801d8ef3e961385246f8 ]

Before this patch, there are two functions will call
i40e_dev_free_queues to free queues. For rte_eth_dev_close(), its
redundant because of duplication. For rte_eth_dev_reset() its
redundant because of not necessary, since following dev_configure
is required after dev_reset and it will be updated correctly.

This patch removes redundant code in i40e_dev_free_queues().

Fixes: 6b4537128394 ("i40e: free queue memory when closing")
