Hi,
I want control the Intel NICs (E810 and X710) DMA to either the hugepage memory on socket 0 or socket 1.  Is there a way to do this in DPDK 24.11?

I have created two mempools, one on socket 0 and one on socket 1.  Now when packets arrive at the NIC receive ports (1 and 2)  I only see mbufs in mempool on the CPU socket where the NIC is located being used to .

Thanks,
Ed

The NIC will use the mempool you pass during configuration in 
rte_eth_rx_queue_setup()

You can also get more detailed with rx segment splitting.
