The value for the receive buffer size when GUEST_TSO{4,6} is negotiated has been
updated in the version 1.4 of the specification in order to allow for larger
packets on IPv6.
IPv6 headers do not eat away from the range of the 16-bit IP packet length
field, which affords 40 additional bytes. The actual increase in the value is 39
instead of 40 because the maximum for the header field is 65535 and not 65536,
which I guess was overlooked when the previous version of the specification was
written.
There was a problem hiding this comment.
