* Various fixes to make de(4) not panic after ru@'s IF_LLADDR() changes:jhb2005-11-212-30/+22
| | | | | | | | | | | | | | | - Don't call tulip_addr_filter() to reset the RX address filter in tulip_reset() since that gets called before ether_ifattach(). Just call it in tulip_init_locked(). - Use be16dec() and le16dec() to parse MAC addresses when programming the RX filter. - Let ether_ioctl() handle SIOCSIFMTU since we were doing the exact same thing with the added bonus that we leaked the driver lock if the MTU was > ETHERMTU in the homerolled version. This part will be MFC'd. Clue from: wpaul (1) Stolen from: marcel (2 via patch for dc(4)) MFC after: 1 week
* - Store pointer to the link-level address right in "struct ifnet"ru2005-11-111-9/+9
| | | | | | | | | | rather than in ifindex_table[]; all (except one) accesses are through ifp anyway. IF_LLADDR() works faster, and all (except one) ifaddr_byindex() users were converted to use ifp->if_addr. - Stop storing a (pointer to) Ethernet address in "struct arpcom", and drop the IFP2ENADDR() macro; all users have been converted to use IF_LLADDR() instead.
* - Use m_defrag() instead of homerolling our own variantjhb2005-08-261-68/+55
| | | | | | | | | | | | | | | tulip_mbuf_compress(). If we fail to allocate a new mbuf to copy the data into, put the mbuf back in the driver's send queue so that we can retry it later rather than throwing the packet away. - Use m_devget() instead of doing it inline ourselves in the TULIP_COPY_RXDATA case. If we fail to allocate an mbuf to copy the data into, don't forget about the original mbuf cluster. The old code would lose the pointer and leak the cluster in that case. Now it doesn't lose it but always sticks the original rx buffer back into the receive ring after trying to copy the data out and send it up the stack. Also, if we fail to allocate a new mbuf to copy the data into, log an input error. Also, don't combine the priming case with the received-a-packet case to make the code flow a bit clearer and easier to follow.
* - Remove non-bus-dma code.jhb2005-08-252-456/+134
| | | | | | | | - Remove form feed characters. - Fixup style of function declarations. - Assume that an mbuf cluster is big enough to hold an ethernet frame. (This should really be using m_defrag(), but this diff is just simple changes for now.)
* Major rototill of this driver to add FreeBSD bus-dma support:jhb2005-08-252-529/+774
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Allocate arrays of metadata for the descriptors in the rx and tx rings and change the ring pointers to walk the metadata array rather than the actual descriptor rings. Each metadata object contains a pointer to its descriptor, a pointer to any associated mbuf, and a pointer to the associated bus_dmamap_t in the bus_dma case. The mbuf pointers replace the tulip_txq and tulip_rxq local ifqueue's in the softc. - Add lots of KTR trace entries using a local KTR_TULIP level which defaults to 0, but can be changed to KTR_DEV at the top of the file when debugging. - Rename tulip_init(), tulip_start(), tulip_ifinit(), and tulip_ifstart() to tulip_init_locked(), tulip_start_locked(), tulip_init(), and tulip_start(), respectively, to match the convention in other drivers. - Add a TULIP_SP_MAC() macro to encode two bytes of the MAC address into the setup buffer and use that in place of lots of BYTE_ORDER #ifdef's. Also, remove an incorrect XXX comment I added earlier, the driver was correct (at least it does the same thing dc(4) does). TULIP_SP_MAC was shamelessly copied from DC_SP_MAC() in dc(4). - Remove the #ifdef'd NetBSD bus-dma code and replace it with FreeBSD bus-dma code that not only compiles but even works at runtime. - Use callout_init_mtx() instead of just callout_init(). - Correct the various wrapper macros for bus_dmamap_sync() for the rx and tx buffers to only ask for the sync ops that they actually need. - Tidy the #ifdef TULIP_COPY_RXDATA code by expanding an #ifdef a bit so it becomes easier to read at the expense of a couple of duplicated lines of code. Also, use m_getcl() to get an mbuf cluster rather than MGETHDR() followed by MCLGET(). - Maintain the ring free (ri_free) count for the rx ring metadata since we no longer have tulip_rxq.ifq_len around to indicate how many mbuf's are currently in the rx ring. - Add code to teardown bus_dma resources when attach fails and generally fixup attach to do a better job of cleaning up when it fails. This gets us a good bit closer to possibly having a detach method someday and making this driver an unloadable module. - Add some functions that can be called from ddb to dump the state of a descriptor ring and to dump the state of an individual descriptor. - Various comment grammer and spelling fixes. I have bus-dma turned on by default, but I've left the non-bus-dma code around so that it can be turned off to aid in debugging should any problems turn up later on. I'll be removing the non-bus-dma code in a subsequent commit.

| | | | | | | | | | | | | | IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

| | | | | | | | | | | | | | | | | | | | 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.
