patch 'dma/dpaa2: set VFA bit for route-by-port with VF' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=11757d12eeed23bfe6da676f147c9ca9bf7ac51e

Thanks.

Subject: [PATCH] dma/dpaa2: set VFA bit for route-by-port with VF
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 92f8be196ada1d4361d35039dbf36427e1358d03 ]

Set the VFA (Virtual Function Active) bit in
struct qdma_sdd -> rbpcmd_simple in order to use the route-by-port
functionality with PCIe virtual functions.

At the moment, a user wanting to enable route-by-port will call
rte_dpaa2_qdma_vchan_rbp_enable with a rte_dpaa2_qdma_rbp struct.

The struct includes the PCIe Physical and Virtual functions among other
things, which are then copied to qdma_sdd -> rbpcmd_simple, but the vfa
bit is never touched (the bit does exists in rbpcmd_simple),
so route-by-port with virtual functions won't work..

In order to fix this, a vfa bit is added to struct rte_dpaa2_qdma_rbp,
then is copied to qdma_sdd -> rbpcmd_simple.

Fixes: 8caf8427f85a ("dma/dpaa2: introduce driver skeleton")
