sys/alpha/conf/GENERIC. Note: the PNIC ignores the lower few bits of the RX buffer DMA address, which means we have to add yet another kludge to make it happy. Since we can't offset the packet data, we copy the first few bytes of the received data into a separate mbuf with proper alignment. This puts the IP header where it needs to be to prevent unaligned accesses. Also modified the PNIC driver to use a non-interrupt driven TX strategy. This improves performance somewhat on x86/SMP systems where interrupt delivery doesn't seem to be as fast with an SMP kernel as with a UP kernel.
