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....
