The interface MTU is suddenly reduced to < Y Before this change, the kernel would be dropping packets till the next PMTUd run. After this change, the PMTUd will be informed that it has to rerun (overriding the pmtud_interval), reducing the packet drop to a minimum. How to test: force knet_bench to send 1500 size packets with ping_data (requires code change) and start it. reduce MTU on the interface from 1500 to 1300 (for example) Notice an immediate trigger of PMTUd run in debug mode Note: going up, from 1300 to 1500 will wait for the next PMTUd re-run as there is no immediate way to detect this change unless we start listening to kernel netlink sockets with libnl3 (investigation in progress but not critical enough atm).
