| | | | | | | | | | | | | | | When de(4) was imported in 1997 the world was not ready for these ioctls. In over 20 years that hasn't changed so it seems safe to assume their time will never come.

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

* Align Tx/Rx descriptors on 32 bytes boundary instead of PAGE_SIZE.Pyun YongHyeon2009-09-241-1/+0
| | | | | | | | | | | | | | | | | | | | | | Also align setup descriptor on 32 bytes boundary. Tx buffer have no alignment limitation so create dmamap without alignment restriction[1]. Rx buffer still seems to require 4 bytes alignment limitation but we can simply use MCLBYTES for size to map the buffer instead of TULIP_DATA_PER_DESC as the buffer is allocated with m_getcl(9). de(4) supports up to TULIP_MAX_TXSEG segments for Tx buffers, increase maximum dma segment size to TULIP_MAX_TXSEG * MCLBYTES. While I'm here remove TULIP_DATA_PER_DESC as it is not used anymore. This should fix de(4) breakage introduced after r176206.

* Various fixes to make de(4) not panic after ru@'s IF_LLADDR() changes:John Baldwin2005-11-211-2/+2
| | | | | | | | | | | | | | | | | | - 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 Notes: svn path=/head/; revision=152666
* - Remove non-bus-dma code.John Baldwin2005-08-251-28/+0
| | | | | | | | | | | - 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.) Notes: svn path=/head/; revision=149476
* Major rototill of this driver to add FreeBSD bus-dma support:John Baldwin2005-08-251-84/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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. Notes: svn path=/head/; revision=149473

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-101-4/+2
| | | | | | | | | | | | | | | | | | | | | | | 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.
