Subject: [PATCH net-next v2 0/2] net: airoha: Improve hwfd
 buffer/descriptor queues setup

Compute the number of hwfd buffers/descriptors according to the reserved
memory size if provided via DTS.
Reduce the required hwfd buffers queue size for QDMA1.

---
Changes in v2:
- Rely on div_u64 to compute number of hw descriptors
- Link to v1: https://lore.kernel.org/r/20250615-airoha-hw-num-desc-v1-0-8f88daa4abd7@kernel.org

      net: airoha: Compute number of descriptors according to reserved memory size
      net: airoha: Differentiate hwfd buffer size for QDMA0 and QDMA1
