Customer needs ethtool v6.2 to be available for GA installation via yum repositories on RHEL9.2.

What were you trying to do that didn't work?

ethtool v5.16 which ships with RHEL9.2 does not print the extended SFP information. But there is a fix in ethtool v6.2 where in ethtool v6.2 where a bug in netlink sff8079_show_all_nl() callnow calls sff8472_show_all() to print the extended SFP module information.

Please provide the package NVR for which bug is seen:

1. ethtool --version
   ethtool version 5.16

How reproducible:

Always Install kernel-5.14.0-284.30.1.el9 run "ethtool -m ens3f0" only the following will be printed with ethtool v5.16:

1. ethtool -m ens3f0
