Looking at the "Porting an io-net driver to io-pkt" document's description of Write process, what happens when a network driver doesn't have any empty buffers and doesn't call IFQ-DEQUEUE()? Will the io-pkt framework retry the write (and when), or will it drop the packet? Thanks, Max

The packet is left queued with the stack by the driver and the next time the stack calls the driver if_start function, hopefully some resources are available.
