| | | | | | | | | | | | Back out r228476. r228476 fixed superfluous link UP/DOWN messages but broke IPMI access during boot. It's not clear why r228476 breaks IPMI and should be revisited. Reported by: Paul Guyot <paulguyot <> ieee dot org > Notes: svn path=/stable/7/; revision=234595

| | | | | | | | | | | | | | | | | | | | | | | | | | Rework link state tracking and remove superfluous link UP/DOWN messages. o Add check for actually resolved speed in miibus_statchg callback instead of blindly reprogramming BCE_EMAC_MODE register. The callback may be called multiple times(e.g. link UP, link transition, auto-negotiate complete etc) while auto-negotiation is in progress. All unresolved link state changes are ignored now and setting BCE_EMAC_MODE after link establishment is done once. o bce(4) is careful enough not to drive MII_TICK if driver got a valid link. To detect lost link, bce(4) relied on link state change interrupt and if driver see the interrupt, it forced to drive MII_TICK by calling bce_tick() in interrupt handler. Because bce(4) generates multiple link state change interrupts while auto-negotiation is in progress, bce_tick() would be called multiple times and this resulted in generating multiple link UP/DOWN messages. With this change, bce_tick() is not called in interrupt handler anymore such that miibus_statchg callback handles link state changes with consistent manner.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r210522: Fix an apparent typo. r213489: Add the capability to read the complete contents of the NVRAM via sysctl dev.bce.<unit>.nvram_dump Add the capability to write the complete contents of the NVRAM via sysctl dev.bce.<unit>.nvram_write These are only available if the kernel option BCE_DEBUG is enabled. The nvram_write sysctl also requires the kernel option BCE_NVRAM_WRITE_SUPPORT to be enabled. These are to be used at your own caution. Since the MAC addresses are stored in the NVRAM, if you dump one NIC and restore it on another NIC the destination NIC's MAC addresses will not be preserved. A tool can be made using these sysctl's to manage the on-chip firmware. r218423: - Added systcls for header splitting, RX/TX buffer count, interrupt coalescing, strict RX MTU, verbose output, and shared memory debug. - Added additional debug counters (VLAN tags and split header frames). - Updated debug counters to 64 bit definitions. - Updated l2fhdr bit definitions. - Combined RX buffer sizing into a single function. - Added buffer size and interrupt coalescing settings to adapter info printout. r218527: - Added error checking to nvram read functions. - Minor style updates.

| | | | | | | | | | | | | | BCE_MISC_ID register of BCM5716 returns the same id of BCM5709 so remove explicit checks for BCM5716. The BCM5709 and BCM5716 chips are virtually indistinguishable by software except for the PCI device ID. The two chips differ in that BCM5709 supports TCP/IP and iSCSI offload in Windows while the BCM5716 doesn't. While I'm here remove now unused definition of BCE_CHIP_NUM_5716 and BCE_CHIP_ID_5716_C0.

| | | | | | | | | | | | | | | | | | | | | | | | - Let mii_phy_add_media() also announce the support of IFM_NONE. - Add a PHY-specific reset routine is for lxtphy(4) which disables MII interrupts. - Remove redundant checks in NIC drivers for mii->mii_instance not being zero before calling the reset routines because as soon as one PHY driver attaches mii->mii_instance is incremented and we hardly can end up in their media change callbacks etc if no PHY driver has attached as mii_attach() would have failed in that case and not attach a miibus(4) instance. - Convert the mebers of the MII data structure to unsigned where appropriate. This is partly inspired by NetBSD/OpenBSD. - Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that weren't explicitly converted to support flow control before. It's unclear whether flow control actually works with these but typically it should and their net behavior should be more correct with these changes in place than without if the MAC driver sets MIIF_DOPAUSE.

Unlike as in NetBSD, IFM_FLOW isn't implemented as a global option via the "don't care mask" but instead as a media specific option this. This has the following advantages: o allows flow control advertisement with autonegotiation to be turned on and off via ifconfig(8) with the default typically being off (though MIIF_FORCEPAUSE has been added causing flow control to be always advertised, allowing to easily MFC this changes for drivers that previously used home-grown support for flow control that behaved that way without breaking POLA) o allows to deal with PHY drivers where flow control advertisement with manual selection doesn't work or at least isn't implemented, like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4), by setting MIIF_NOMANPAUSE o the available combinations of media options are readily available from the `ifconfig -m` output - Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so these are understood by ifconfig(8). o Make the master/slave support in mii(4) actually usable: - Change IFM_ETH_MASTER from being implemented as a global option via the "don't care mask" to a media specific one as it actually is only applicable to IFM_1000_T to date. - Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to actually configure manually selected slave mode (like we also do in the PHY specific implementations). - Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it is understood by ifconfig(8). o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4), e1000phy(4) and ip1000phy(4) to use the generic flow control support instead of home-grown solutions via IFM_FLAGs. This includes changing these PHY drivers and smcphy(4) to no longer unconditionally advertise support for flow control but only if the selected media has IFM_FLOW set (or MIIF_FORCEPAUSE is set) and implemented for these media variants, i.e. typically only for copper. o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0 and some IFM_FLAGn. o Switch brgphy(4) to add at least the the supported copper media based on the contents of the BMSR via mii_phy_add_media() instead of hardcoding them. The latter approach seems to have developed historically, besides causing unnecessary code duplication it was also undesirable because brgphy_mii_phy_auto() already based the capability advertisement on the contents of the BMSR though. o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not just BCM5701. Apparently this was a misinterpretation of a workaround in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but this doesn't mean we can't set these as well on other PHYs for manual media selection. o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so IFM_1000_T master mode support now is generally available with all PHY drivers. o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's not applicable there. Reviewed by: yongari (plus additional testing) Obtained from: NetBSD (partially), OpenBSD (partially) Unlike as in head, bge(4), bce(4), msk(4), nfe(4) and stge(4) are changed to set MIIF_FORCEPAUSE in stable/7 so they continue to always advertise support of flow control and brgphy(4), ciphy(4), e1000phy(4) as well as ip1000phy(4) are changed to still also accept IFF_LINK0 in addition to the master media option for setting master mode, both in order to not violate POLA.

| | | | | | | | | | | | | | Make sure to not use stale ip/tcp header pointers. The ip/tcp header parser uses m_pullup(9) to get access to mbuf chain. m_pullup(9) can allocate new mbuf chain and free old one if the space left in the mbuf chain is not enough to hold requested contiguous bytes. Previously drivers can use stale ip/tcp header pointer if m_pullup(9) returned new mbuf chain. Reported by: Andrew Boyer (aboyer <> averesystems dot com) Notes: svn path=/stable/7/; revision=214296

This would cause extremely slow performance when used with NFS over UDP. - Removed untested polling code. - Updated copyright year in the file header. - Removed inadvertent ^M's created by DOS text editor. r178853 (scottl) The BCE chips appear to have an undocumented requirement that RX frames be aligned on an 8 byte boundary. Prior to rev 1.36 (now r176448) this wasn't a problem because mbuf clusters tend be naturally aligned. The switch to using split buffers with the first buffer being the embedded data area of the mbuf has broken this assumption, at least on i386, causing a complete failure of RX functionality. Fix this for now by using a full cluster for the first RX buffer. A more sophisticated approach could be done with the old buffer scheme to realign the m_data pointer with m_adj(), but I'm also not clear on performance benefits of this old scheme or the performance implications of adding an m_adj() call to every allocation. r179436 (jhb) Trim an extra semi-colon. r179695 (davidch) - Fixed kern/123696 by increasing firmware timeout value from 100 to 1000. - Fixed a problem on i386 architecture when using split header/jumbo frame firmware caused by hardware alignment requirements. - Added #define BCE_USE_SPLIT_HEADER to allow the feature to be enabled/disabled.

| | | | | | | | | | | | | | | | | | | | | | | descriptor's mbuf pointer to see if the transmit ring is full. The mbuf pointer is set only in the last descriptor of a multi-descriptor packet. By relying on the mbuf pointers of the earlier descriptors, the driver would sometimes overwrite a descriptor belonging to a packet that wasn't completed yet. Also, tx_chain_prod wasn't updated inside the loop, causing the wrong descriptor to be checked after the first iteration. The upshot of all this was the loss of some transmitted packets at medium to high packet rates. In bce_tx_encap, remove a couple of old statements that shuffled around the tx_mbuf_map pointers. These now correspond 1-to-1 with the transmit descriptors, and they are not supposed to be changed. Correct a couple of inaccurate comments. MFC after: 1 month Notes: svn path=/head/; revision=164327
