* Deprecate a number of less used 10 and 10/100 Ethernet devices.Brooks Davis2018-10-251-0/+2
| | | | | | | | | | | | | | The current deprecated list is: ae, bm, cs, de, dme, ed, ep, ex, fe, pcn, sf, sn, tl, tx, txp, vx, wb, xe The list as refined as part of FCP-0101. Per the FCP, devices may be removed from the deprecation list if enough users are found or they are converted to iflib.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Run on LLNW canaries and tested by pho@ gallatin: Using a 14-core, 28-HTT single socket E5-2697 v3 with a 40GbE MLX5 based ConnectX 4-LX NIC, I see an almost 12% improvement in received packet rate, and a larger improvement in bytes delivered all the way to userspace.

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-273-0/+6
| | | | | | | | | | | | | | | 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

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

| | | | | | | | | | | | | In Rx path it allocates a new mbuf with m_getcl(9) so the length of the mbuf is MCLBYTES which is greater than a segment size specified by the dma tag. This segment size mismatch caused a voluntary panic. Fix the panic by settting the mbuf length to TULIP_DATA_PER_DESC.

* Various fixes to make de(4) not panic after ru@'s IF_LLADDR() changes:John Baldwin2005-11-212-30/+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 Notes: svn path=/head/; revision=152666
* - Store pointer to the link-level address right in "struct ifnet"Ruslan Ermilov2005-11-111-9/+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. Notes: svn path=/head/; revision=152315
* - Use m_defrag() instead of homerolling our own variantJohn Baldwin2005-08-261-68/+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. Notes: svn path=/head/; revision=149497

* Major rototill of this driver to add FreeBSD bus-dma support:John Baldwin2005-08-252-529/+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. Notes: svn path=/head/; revision=149473
