No more recursive lock required.- bus_dma(9) conversion. I think it should work on all architectures.- optimized Rx handler for each normal and jumbo frames. Previously sk(4) used jumbo frame management code to handle normal sized frames. As the handler needs an additional lock to protect jumbo frame management structure from races, it used two lock operations for each received packet. Now sk(4) uses single lock operation for normal frame.(Jumbo frame still needs two lock operations as before.) The hardware supports DMA scatter operations for Rx descriptors such that it's possible to take advantagee of m_cljget(9) for jumbo frames. However, due to a unknown reasons it resulted in poor performance on sparc64. So I dropped m_cljget(9) approach. This should be revisited since it would reduce one lock operation for jumbo frame handling.- Tx TCP/Rx IP checksum offload support. According to the data sheet of SK-NET GENESIS the hardware supports Rx IP/TCP/UDP offload. But I couldn't make it work on my Yukon hardware. So Rx TCP/UDP was disabled at the moment. It seems that newer Yukon chips can support Tx UDP checksum offload too. But I need more documentation first.- Added more wait time in reading VPD data. It seems that ASUS LOM takes a very long time to respond VPD read signal.- Added an additional lock for MII register access callbacks.- Added more strict received packet validation routine. Previously it passed corrupted packets to upper layers under certain conditions.- A new function sk_yukon_tick() to handle auto-negotiation properly.- Interrupt handler now checks shared interrupt source and protects the interrupt handler from NULL pointer dereference which was caused by odd status word value. The status word can returns 0xffffffff if cable is unplugged while Rx/Tx/auto-negotiation is in progress.- suspend/resume support(not tested).- Added Rx/Tx FIFO flush routine for Yukon- Activate Tx descriptor poll timer in order to protect possible loss of SK_TXBMU_TX_START command. Previously the driver continuously issued SK_TXBMU_TX_START when it notices pending Tx descriptors not processed yet in interrupt handler. That approach would add additional PCI write access overhead under high Tx load situations and it might fail if the first SK_TXBMU_TX_START was lost and no interrupt is generated from the first SK_TXBMU_TX_START command.- s/printf/if_printf/, s/printf/device_printf/, Axe sk_unit in softc.- Setting multicast/station address is now safe on strict-alignment architectures.- Fix long standing bug in VLAN header length setup.- Added/corrected register definitions for Yukon. (Register information from Linux skge driver.)- Added Rx status definition for Marvell Yukon/XaQti XMAC. (Rx status register information from Linux skge driver.)- Update if_oerrors if we encounter watchdog error.- callout(9) conversionSpecial thanks to jkim who let me know RX status differences betweenYukon and XaQti XMAC.It seems that there is still occasional watchdog timeout error but Icouldn't reproduce it and need more information to analyze it fromusers.Tested by: bz(amd64), me(i386, sparc64), current ML Frank Behrens frank ! pinky ( sax $ de List of files: /freebsd/sys/dev/sk/yukonreg.h Thu, 27 Apr 2006 07:59:09 +0200 Pyun YongHyeon <yongari@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/dev/sk/yukonreg.h#60727d8b86294910d41cbda1a50a855ea0537449 /* -> /*- for license, minor formatting changes List of files: /freebsd/sys/dev/sk/yukonreg.h Fri, 07 Jan 2005 03:29:27 +0100 Warner Losh <imp@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/dev/sk/yukonreg.h#95ad0a1f289c93d623dc3e3d19f735e170f53da7 Add missing file, it is sorely needed to make if_sk.c compile again.
