linux-toradex.git/drivers/net/bnx2.h, branch v2.6.36-rc2 Linux kernel for Apalis and Colibri modules bnx2: Call pci_enable_msix() with actual number of vectors. 2010-07-20T03:30:06+00:00 Michael Chan mchan@broadcom.com 2010-07-19T14:15:03+00:00 379b39a2ad613745bfbfe80256957d19689b7b94 Based on original patch by Breno Leitão <leitao@linux.vnet.ibm.com>. Allocate the actual number of vectors and make use of fewer vectors if pci_enable_msix() returns > 0. We must allocate one additional vector for the cnic driver.

Use prefetchw() for the skb [suggested by Eric Dumazet]. The rx descriptor is in skb->data which is mapped for streaming mode DMA. Eric Dumazet pointed out that we should not prefetch the data before dma_sync. So we prefetch only if dma_sync is no_op on the system.
