pespin has submitted this change. ( https://gerrit.osmocom.org/c/upf-benchmark/+/39574?usp=email ) Change subject: testsuites/gtplab-sysmo2017/tunend: Disable GRO/LRO ...................................................................... testsuites/gtplab-sysmo2017/tunend: Disable GRO/LRO This can cause problems on incoming decaps traffic from CN (eg. TCP), which may end up being joined into a bigger packet which will then fail to be encapsulated into UDP fitting an MTU of 1500. This didn't show up specifically during tests since we are crafting UE UDP traffic with proper size in order to fit the MTU, but it would have shown up if TCP was used.
