LAN9420I-NU General Description
One of the key advantages of the LAN9420/LAN9420i controller is its descriptor-based scatter-gather DMA, which enables zero-copy drivers for increased throughput and reduced Host load. Additionally, the integrated IRQ deassertion timer allows for precise control over IRQ deassertion time, further optimizing system performance. Support for automatic 32-bit CRC generation/checking, payload padding, and 2K jumbo packets enhances data integrity and transmission efficiency
