This patch set add netdev_level_ratelimited to avoid netdev msg flush. The second patch fixed ibmveth msg flush when add lots of(e.g. 2000) group memberships in one group at the same time.
In my testing, there will be the ibmveth 30000003 env3: h_multicast_ctrl rc=4 when adding an entry to the filter table error when add more thann 256 memberships in one multicast group. I haven't found this issue on other driver. It looks like an ibm driver issue and need to be fixed separately. v2: add netdev_level_ratelimited as Joe Perches suggested Hangbin Liu (2): netdevice.h: add netdev_level_ratelimited for netdevice ibmveth: use net_err_ratelimited when set_multicast_list drivers/net/ethernet/ibm/ibmveth.c | 5 ++- include/linux/netdevice.h | 53 ++++++++++++++++++++++++++++++ 2 files changed, 55 insertions(+), 3 deletions(-) -- 2.19.2
