Hi, In general netmap adapters (i.e. netmap ports) may support NS_MOREFRAG. But in practice this is mainly supported on VALE ports. So if you don't want to add the missing support by yourself you can simply change the netmap buffer size by tuning the sysctl dev.netmap.buf_size, and increase it to 9600.
