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

[Stanislav Fomichev]

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

- move shared freelist state and operations into net_iov_area
- 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

Stanislav Fomichev (3):
  net: netmem: add net_iov_area freelist helpers
  net: devmem: use memory provider helpers for net_iovs
  net: devmem: decode DMA addresses for TX
