From: Ursula Braun <redacted> Setting an invalid mac-address for a qeth layer2 device returns with a strange error code: # ip link set hsi1 address 00:00:00:00:00:01 RTNETLINK answers: Unknown error 18446744073709486085 Problem is caused by wrong usage of the return_code field within structure qeth_ipa_cmd. With this patch the ip command above returns SIOCSIFHWADDR: Invalid argument Signed-off-by: Ursula Braun <redacted> Signed-off-by: Frank Blaschka <redacted> --- drivers/s390/net/qeth_core_main.c | 6 +++--- drivers/s390/net/qeth_core_mpc.c | 1 + drivers/s390/net/qeth_core_mpc.h | 1 + drivers/s390/net/qeth_l2_main.c | 4 +--- drivers/s390/net/qeth_l3_main.c | 2 +- 5 files changed, 7 insertions(+), 7 deletions(-)
