Lorenzo Bianconi says:

====================
Add the capability to consume SRAM for hwfd descriptor queue in airoha_eth driver

In order to improve packet processing and packet forwarding
performances, EN7581 SoC supports consuming SRAM instead of DRAM for hw
forwarding descriptors queue. For downlink hw accelerated traffic
request to consume SRAM memory for hw forwarding descriptors queue.
Moreover, in some configurations QDMA blocks require a contiguous block
of system memory for hwfd buffers queue. Introduce the capability to
allocate hw buffers forwarding queue via the reserved-memory DTS
property instead of running dmam_alloc_coherent().
