[PATCH 03/11] net/enetfec: fix buffer descriptor size configuration

[Hemant Agrawal]

The driver previously allowed arbitrary descriptor counts, which could
lead to misaligned buffer allocations. This patch enforces the use of
fixed descriptor ring sizes for both RX and TX queues, ensuring proper
buffer allocation and avoiding potential runtime issues.
