new test kernel works as expected:

Linux version 5.15.0-47-generic

# grep qcrdinfo /5.15.0-48-genericsys/kernel/debug/s390dbf/qeth*/hex_ascii | wc -l
7
# ethtool encbd00 | grep Duplex
Duplex: Full
# grep qcrdinfo /sys/kernel/debug/s390dbf/qeth*/hex_ascii | wc -l
9

afterupdate to Linux version 5.15.0-48-generic

# grep qcrdinfo /sys/kernel/debug/s390dbf/qeth*/hex_ascii | wc -l
0
# ethtool encbd00 | grep Duplex
Duplex: Full
# grep qcrdinfo /sys/kernel/debug/s390dbf/qeth*/hex_ascii | wc -l
