net: stmmac: Switch to zero-copy in non-XDP RX path
Avoid memcpy in non-XDP RX path by marking all allocated SKBs to
be recycled in the upper network stack.
This patch brings ~11.5% driver performance improvement in a TCP RX
throughput test with iPerf tool on a single isolated Cortex-A65 CPU
core, from 2.18 Gbits/sec increased to 2.43 Gbits/sec.
