Hi Jochen, The VMXNET3 driver supports two different max MTU sizes, depending on VMware guest version: https://elixir.bootlin.com/dpdk/latest/source/drivers/net/vmxnet3/vmxnet3_ethdev.c#L1650
I think the reported max MTU size should reflect this too, e.g.: https://elixir.bootlin.com/dpdk/latest/source/drivers/net/vmxnet3/vmxnet3_ethdev.c#L1564 - dev_info->max_mtu = VMXNET3_MAX_MTU; + dev_info->max_mtu = VMXNET3_VERSION_GE_6(hw) ? VMXNET3_V6_MAX_MTU : VMXNET3_MAX_MTU; Med venlig hilsen / Kind regards, -Morten Brørup
