This series improves RX performance a lot, ~34% TCP RX throughput boost
has been observed with DWXGMAC CORE 3.20a running on Cortex-A65 CPUs:
from 2.18 Gbits/sec increased to 2.92 Gbits/sec.

Changes in v2:
  1. No cache prefetch for frags (Alexander Lobakin)
  2. Fix code style warning reported by netdev CI on Patchwork

  v1: https://patchwork.kernel.org/project/netdevbpf/list/?series=924103&state=%2A&archive=both

Furong Xu (3):
  net: stmmac: Switch to zero-copy in non-XDP RX path
  net: stmmac: Set page_pool_params.max_len to a precise size
  net: stmmac: Optimize cache prefetch in RX path
