patch 'net/axgbe: check only minimum speed for cables' has been queued to stable release 21.11.8

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/24. 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

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/1f85d756aa324f2064bfc09f85ba1a5d6add52b9

Thanks.

Kevin

Subject: [PATCH] net/axgbe: check only minimum speed for cables

[ upstream commit b5587a39dc94ee0bd055b515cc8c060923ed69b9 ]

There are cables that exist that can support speeds in excess of 10GbE.
The driver, however, restricts the EEPROM advertised nominal bitrate to
a specific range, which can prevent usage of cables that can support,
for example, up to 25GbE.

Rather than checking that an active or passive cable supports a specific
range, only check for a minimum supported speed.

Fixes: a5c7273771e8 ("net/axgbe: add phy programming APIs")
