parentnet: phy: dp83867: Fix warning check for setting the internal delay (diff)
ravb: fix ring memory allocation
The driver is written as if it can adapt to a low memory situation allocating less RX skbs and TX aligned buffers than the respective RX/TX ring sizes. In reality though the driver would malfunction in this case. Stop being overly smart and just fail in such situation -- this is achieved by moving the memory allocation from ravb_ring_format() to ravb_ring_init(). We leave dma_map_single() calls in place but make their failure non-fatal by marking the corresponding RX descriptors with zero data size which should prevent DMA to an invalid addresses.
