Subject: [PATCH RFC net-next 0/6] net: macb: Add XDP support and page pool integration

Testing were performed on Raspberry Pi 5 with upstream kernel
and all the changes are intended for gem only.

The series consists of two main changes:

- Migration from netdev_alloc_skb() to page pool allocation,
  enabling skb recycling.
  This also adds support for multi-descriptor frame reception,
  removing the previous single-descriptor approach and avoiding
  potentially large contiguous allocations for e.g. jumbo frames
  with CONFIG_PAGE_SIZE_4KB.

- XDP support: Complete XDP implementation supporting all major
  verdicts (XDP_PASS, XDP_DROP, XDP_REDIRECT, XDP_TX) along with
  the ndo_xdp_xmit function for packet redirection.

The driver now advertises NETDEV_XDP_ACT_BASIC, NETDEV_XDP_ACT_REDIRECT,
NETDEV_XDP_ACT_NDO_XMIT capabilities.

Paolo Valerio (6):
  cadence: macb/gem: Add page pool support
  cadence: macb/gem: handle multi-descriptor frame reception
  cadence: macb/gem: use the current queue number for stats
  cadence: macb/gem: add XDP support for gem
  cadence: macb/gem: make tx path skb agnostic
  cadence: macb/gem: introduce xmit support
