Joao, you have a really powerful HW integration with multiple channels
for both RX and TX.
Often this is not the same for other setup where, usually just a DMA0
is present or, sometime, there
is just one RX extra channel.
My question is, what happens on this kind of configurations? Are we
still guarantying the best performances?
Also we have to guarantee, that the TSO and SG are always working.
Another point is the buffer sizes that
can be different among platforms.
The problem below reported by Corentin push me to think that there is
a bug, so we should
understand when this has been introduced and if likely fixed by some
configuration we are
not take care right now.
ndesc_get_rx_status: Oversized frame spanned multiple buffers"
I wonder if this could be easily triggered by getting a big file via
FTP. So not properly related on performance benchs
