JackDoan 1d768ac4e4 tio: accept VIRTIO_NET_HDR_GSO_ECN-qualified superpackets 
TUN_F_TSO_ECN is negotiated, so once ECN feedback flows the kernel hands
us TSO superpackets typed TCPV4|GSO_ECN (CWR set). protoFromGSOType
treated the qualifier bit as an unknown type and the read path dropped
every such superpacket - a latent bug that only fires when a congested
hop CE-marks the flow, exactly when drops hurt most. The segmenter
already handles CWR (first segment only); just mask the bit.
