[lwip-users] Driver question

[Ivan Warren]

Hi,

I am writing an ethernet driver for my system and I was wondering :

Is there a way to indicate for inbound packets that more than one packet 
was received ?

Can I cram more than a single frame in a single pbuf, or do I have to 
split out each packet, put them into pbufs and call netif->input() 
repeatedly ? (or send a pbuf queue to netif->input() ?)

And would that be advantageous ?

I'm asking because when running iperf, it seems that the TCP layer is 
acknowledging *EVERY* datagram it receives (wich contain a payload) - 
which may be superfluous (which *may* be because the TCP stack isn't 
aware there are more coming !)

Sorry, these are probably newbie questions....
