Dear All, When running dhcp tests using the 4.4.y (and 4.4.y-cip kernel as well), I encountered an issue where the dhcp client in the kernel could not get an IP address when multiple network devices were enabled. It seems that the current implementation of the dhcp client in the 4.4 kernel is send dhcp request via device 1 -> wait <1s for response from server on device 1 -> if no response, switch to device 2 -> repeat process on device 2 ...etc. When the dhcp server is slow to respond, this means it is impossible to get a dhcp address. This series backported from upstream fixes the issue, is it possible to apply this to 4.4.y and/or 4.4.y-cip?
This is something that seems more suited for the CIP kernel as it adds new functionality. -- Thanks, Sasha
