Hi,
I just have some questions about the packet splitting which is supported by
some PCI-express platforms. It seems the packet data buffer part (header and
payload) is splitted into several parts and stored into different buffers
while PCI-X NIC use 2K data buffer for every packet.
My question is: what is the purpose of this packet splitting? It seems each
splitted part has different size, why not choose a uniform size for each
part?
It seems it serve the same purpose as copybreak. Can anyone please me give
some more hints.
Thanks a lot,
John
