Question about network device - Legacy Interface: Device Operation

Hi,

while reading chapter "5.1.6.1 Legacy Interface: Device Operation" in
draft 05, I noticed following sentence:

"The legacy driver only presented num_buffers in the struct
virtio_net_hdr when VIRTIO_NET_F_MRG_RXBUF was not negotiated; without
that feature the structure was 2 bytes shorter."

Shouldn't that be "... was negotiated ..." instead of "... was not
negotiated ..."? Otherwise this sounds quite contradictory to me.
