MFp4(simokawa_firewire): Many internal structure changes for the FireWire driver. - Compute CRC in CROM parsing. - Add support for configuration ROM build. - Simplify dummy buffer handling. - busdma conversion - Use swi_taskqueue_giant for -current. Mark the interrupt routine as MPSAFE. - AR buffer handling. Don't reallocate AR buffer but just recycle it. Don't malloc and copy per packet in fwohci_arcv(). Pass packet to fw_rcv() using iovec. Application must prepare receiving buffer in advance. - Change fw_bind API so that application should pre-allocate xfer structure. - Add fw_xfer_unload() for recycling struct fw_xfer. - Add post_busreset hook - Remove unused 'sub' and 'act_type' in struct fw_xfer. - Remove npacket from struct fw_bulkxfer. - Don't call back handlers in fwochi_arcv() if the packet has not drained in AT queue - Make firewire works on big endian platform. - Use native endian for packet header and remove unnecessary ntohX/htonX. - Remove FWXFERQ_PACKET mode. We don't use it anymore. - Remove unnecessary restriction of FWSTMAXCHUNK. - Don't set root node for phy config packet if the root node is not cycle master capable but set myself for root node. We should be the root node after next bus reset. Spotted by: Yoshihiro Tabira <tabira@scd.mei.co.jp> - Improve self id handling Tested on: i386, sparc64 and i386 with forced bounce buffer

MFp4(simokawa_sbp) Improve if_fwe performance. - Simplify mbuf handling by using bulkxfer. Now, it uses mbuf clusters for RX buffer as usual ethernet drivers. - Recycle struct xfer buffer and don't call malloc at runtime. - Count input and output errors. - Handle a mbuf chain longer than 6 correctly. - Increase queue length.

struct fwe_eth_softc {
Stop embedding struct ifnet at the top of driver softcs. Instead the struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.
