o s/printf/device_printf/g o Nuke OpenBSDism. o Nuke NetBSD/OpenBSD specific DMA sync operations.(we don't have a way to sync a single descriptor within a DMA map.) o Remove recursive mutex. o bus_dma(9) clean up. o 40bit DMA address support. o Add protection for Rx map load failure. o Fix a long standing bug for watchdog timeout. [1] o Add additional protections, missing Tx completion interrupt, losing start Tx command, for watchdog timeout. o Switch to taskqueue(9) API to handle interrupts. o Use our own timer for watchdog instead of if_watchdog/if_timer interface. o Advertise VLAN header length/capability correctly to upper layer. o Remove excessive kernel stack consumption in nfe_encap(). o Handle highly fragmented mbuf chains correctly. o Enable etherenet address reprogramming with ifconfig(8). o Add ALTQ/TSO, MSI/MSIX support. o Increased Rx ring to 256 descriptors from 128. o Align Tx/Rx descriptor ring on sizeof(struct nfe_desc64) boundary. o Remove alignment restrictions on Tx/Rx buffers. o Rewritten jumbo frame support code. o Add support for hardware assistend VLAN tag insertion/stripping. o Add support for Tx/Rx flow control based on patches from Peer Chen. [2] o Add a routine that detects whether ethernet address swap routines is required. [3] o Add a workaround that take MAC/PHY out of power down mode. o Add suspend/resume support. o style(9) and code clean up. Special thanks to Shigeaki Tagashira, the original porter of nfe(4), who submitted lots of patches, performed uncountable number of regression tests and maintained nfe(4) for a long time. Without his enthusiastic help and support I could never have completed this overhauling task. The only weak point of nfe(4) compared to nve(4) is instability of manual half-duplex media selection on certain hardwares(auto sensing media type should work for all cases, though). This was a long standing bug of nfe(4) and I still have no idea why it doesn't work on some hardwares.
