patch 'net/axgbe: fix SFP codes check for DAC 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/35429aa99d616f707ca5ad14c528b6195ebe5715

Thanks.

Kevin

Subject: [PATCH] net/axgbe: fix SFP codes check for DAC cables

[ upstream commit 4eefb1b16acaa69bd757057e0c54c58f11577ba3 ]

The current axgbe code assumes that offset 6 of EEPROM SFP DAC (passive)
cables is NULL. However, some cables (the 5 meter and 7 meter Molex
passive cables) have non-zero data at offset 6. Fix the logic by moving
the passive cable check above the active checks, so as not to be
improperly identified as an active cable. This will fix the issue for
any passive cable that advertises 1000Base-CX in offset 6.

Without the fix the user will not get link UP for few DAC cables.

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