[PATCH net-next v2 0/3] net: consolidate devmem net_iov freelist and DMA handling

[Stanislav Fomichev]

Follow up on the recently merged devmem gen_pool removal by consolidating
devmem's net_iov freelist and DMA-address handling.

- move devmem freelist to index-based approach with push/pop helpers
- switch devmem to public memory-provider helpers and reject DMA
  addresses that cannot be represented
- decode stored DMA addresses for TX on 32-bit systems with 64-bit
  dma_addr_t

v2:
- drop io_uring conversion (Pavel)

Stanislav Fomichev (3):
  net: netmem: move to index based freelist
  net: devmem: use memory provider helpers for net_iovs
  net: devmem: decode DMA addresses for TX
