You’d have to have more than one, sure. You might be able to ping-pong
between 2 – but without copying you stand to lose packets if you don’t finish
with the first and the second one has come in and then a third is pending. Bill i suppose i could have a driver with more than one pbuf
allocated... it could be more efficient... but, my problem, is the pbuf
allocation memory: DMA MUST works in FIXED region in memory, and instead i have
no control where pbuf payload are allocated... do you have a solution? |
