This patch provides some general performance enhancements for the
driver:
- Modify the default coalescing settings (reduce usec, increase frames)
- Change the AXI burst length to 256 bytes (default was 16 bytes which
was smaller than a cache line)
- Change the AXI cache settings to write-back/write-allocate which
allocate cache entries for received packets during the DMA since the
packet will be processed soon afterwards
- Combine ioread/iowrite when disabling both the Tx and Rx interrupts
- Change to processing the Tx/Rx channels in pairs
- Only recycle the Rx descriptors when a threshold of dirty descriptors
is reached
