rh-ee-xudu reported a problem with setting tcp-data-split in RHEL-32112. I investigated and found the following:

Disabling tcp-data-split on idpf silently fails:
# ethtool -G $NETDEV tcp-data-split off
# ethtool -g $NETDEV | grep 'TCP data split'
TCP data split: on

But it works if you also change 'tx' or 'rx':
# ethtool -G $NETDEV tcp-data-split off tx 256
# ethtool -g $NETDEV | grep 'TCP data split'
TCP data split: off

The bug is in idpf_set_ringparam, where it takes a shortcut out if the
TX and RX sizes are not changing.

Please provide the package NVR for which bug is seen:

The CKI build from RHEL-29553.
