> When random number of Tx segments is enabled, because the actual number of
> segments may be only one, the first segment of the Tx packets must
> accommodate a complete being sending Eth/IP/UDP packet.
>
> Besides, if multiple flow is enabled, the forwarding will update the IP and UDP
> header, these headers shouldn't cross segments.
> This also requires the first Tx segment can accommodate a complete
> Eth/IP/UDP packet.
>
> In addition, if time stamp is enabled, the forwarding needs more Tx segment
> space for time stamp information.
>
> This patch adds checks in beginning of forward engine to make sure all above
> conditions are met.
