the pagesize is 64KB,
the online cpu number is 256.
the rx_buf_len is ICE_RXBUF_2048.
fllow the source code,
ice_vsi_cfg()
---->ice_vsi_cfg_rxqs()
{
...
ice_vsi_cfg_frame_size(vsi);----pagesize < 8192 or pagesize > 8192
ice_for_each_rxq(vsi, i) {
int err = ice_vsi_cfg_rxq(vsi->rx_rings[i]);
...
}
ice_alloc_rx_bufs
---->ice_alloc_mapped_page
---->dev_alloc_pages(ice_rx_pg_order(rx_ring));
So, will be alloce 2(one card, two functions dev) multiplied by 256 （min
msix/online cpus） multiplied by 2048 (revice queue pairs) multiplied by 64K(
the pagesize) .
if the pagesize is 16KB or 64KB , the queue pairs need more less or not . and
how many queue pairs will be ok.
