[dpdk-stable] patch 'net/hns3: fix device capabilities for copper media type' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/e4e0a6505d77bec24938065bc77ecd0a74e02ae8

Thanks.

Subject: [PATCH] net/hns3: fix device capabilities for copper media type
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 68ed5ee49de7f6e3a57c5ecca812b3bbcced6bbf ]

The configuration operation for PHY is implemented by firmware. And
a capability flag will be report to driver, which means the firmware
supports the PHY driver.  However, the current implementation only
supports obtaining the capability bit, but some basic functions of
copper ports in driver, such as, the query of link status and link
info, are not supported.

Therefore, it is necessary for driver to set the copper capability
bit to zero when the firmware supports the configuration of the PHY.

Fixes: 438752358158 ("net/hns3: get device capability from firmware")
Fixes: 95e50325864c ("net/hns3: support copper media type")
