Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/24/19. 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/qede: support IOVA VA mode

[ upstream commit 7aac5899df81f40c07a8047f410e7f2fcc62962d ]

Set RTE_PCI_DRV_IOVA_AS_VA in drv_flags. This allows initializing qede
PMD as non-root also on Linux v4.x, where /proc/self/pagemap can't be
acccessed without CAP_SYS_ADMIN privileges.

The flag was introduced generically but not in pmds in:
commit 815c7deaed2d ("pci: get IOMMU class on Linux")
