[dpdk-stable] patch 'net/qede: use ack in interrupt handlers' has been queued to LTS release 18.11.6

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/17/19. 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.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/9b30de5d63f0166e3b77bee7ad5c62d3fc4aaaca

Thanks.

Kevin.

Subject: [PATCH] net/qede: use ack in interrupt handlers

This is a partial pick of below commit from master. At this point
only qede is updated as it addresses an observed issue.

    drivers/net: use ack in interrupt handlers

    Replace rte_intr_enable() with rte_intr_ack() API
    for acking an interrupt in interrupt handlers and
    rx_queue_intr_enable() callbacks of PMD's.

    This is inline with original intent of this change in PMDs
    to ack interrupts after handling is completed if
    device is backed by UIO, IGB_UIO or VFIO(with INTx).
