Hello All Would you please look at kernel bug report "Since 4.12 - bonding module not working with wireless drivers", and tell me if you know why the kernel ethtool does not receive a speed report from the wireless drivers?
https://bugzilla.kernel.org/show_bug.cgi?id=196547 It seems that Mahesh Bandewar became annoyed that some network drivers do not report speed and duplex to the bonding module properly, so that it becomes impossible to make "best connection" decisions. A patch was applied to the bonding module in linux 4.12 which now disables any network interface that does not successfully report its speed and duplex. In practice, this seems to include every wireless network driver I've tried, the ath5k, ath9k, the rtl8192ce and RTL8188CUS. Of course, this new behavior breaks wireless bonding! Do you know if there is some general reason why the wireless drivers do not work with the kernel ethtool? Is this something that can be fixed? Can you tell if this reporting failure would be the fault of the kernel ethtool? Or the wireless driver? Or the bonding module? Thanks James
