Description

It would be nice to have a configurable number of Rx groups in i40e via the driver conf, much like ixgbe has. This can be especially useful in the current i40e dirver which is DMA heavy on the Rx side, requiring a fair amount of static memory on attach based on the number of Rx groups and their ring sizes.

To test I raised and lowered rx_num_groups in i40e.conf and made sure the driver attached with that number of Rx mac groups.
