[v4,14/18] net/i40e/base: separate kernel allocated rx_bi rings from AF_XDP rings
Checks
Commit Message
Continuing the path to support MEM_TYPE_XSK_BUFF_POOL, the AF_XDP
zero-copy/sk_buff rx_bi rings are now separate. Functions to properly
allocate the different rings are added as well.

commit in shared code drop for DPDK?
