[dpdk-stable] patch 'net/i40e/base: fix update link data for X722' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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/7d5375f7d7f8e71ca1e95bdd8ea4a0292f835280

Thanks.

Subject: [PATCH] net/i40e/base: fix update link data for X722
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 74bd4072996e64b0051d24d8d641554d225db196 ]

The X722 card has 'Link Type' information elsewhere than the X710.
Previously, for all cards, the 'Link Type' information was retrieved by
opcode 0x0607 and this value was wrong for all X722 cards.
Now this information for X722 only is taken by opcode 0x0600
(function: i40e_aq_get_phy_capabilities) instead of an opcode
0x0607 (function: i40e_aq_get_link_info).
All other parameters read by opcode 0x0607 unchanged.

Fixes: e6691b428eb1 ("i40e/base: fix PHY NVM interaction")
Fixes: 75c3de654ead ("net/i40e/base: fix long link down notification time")
