So this example uses the most recent NCM driver? (you can identify it with my name in the copyright (Hardy Griech)) What is on the host side?

One more thing: @HiFiPhile introduced one significant change during reformat. CFG_TUD_NCM_IN_NTB_MAX_SIZE/CFG_TUD_NCM_OUT_NTB_MAX_SIZE was changed from "(2 * TCP_MSS + 100)" to "3200". Could you please test with the old values?
