Hi All,
The MTU by default is 1500. But for the RX_BUFFER the packet size should atleast be 2048. So does this mean that for DPDK to work there should be MTU of atleast 2048?
Thanking You,
Param.

DPDK uses 2048 byte buffers for aligning memory as 1500 is and odd size for memory buffers. You should still use the standard MTU values for non-jumbo frames.
