[Bug 1063038] Re: Broadcom BCM57780 Cannot Connect at Gigabit Speed using tg3 module.
As per upstream in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1063038/comments/27 the device is rate limited in firmware intentionally. Hence, while it is technically possible to override this from a firmware perspective (i.e. Acer+Broadcom would release a firmware update), from a linux project perspective, investigating and, if viable, implementing an override of said firmware rate limiting as it stands today would need to be done upstream. ** Changed in: linux (Ubuntu) Importance: Undecided => Wishlist ** Changed in: linux (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063038 Title: Broadcom BCM57780 Cannot Connect at Gigabit Speed using tg3 module.

Justin Chudgar, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (1.10). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags removed: tg3 ** Tags added: bios-outdated-v1.10 ** Tags removed: broadcom gigabit ** Description changed: I've got a device with a Broadcom 57780 ethernet NIC. It uses the tg3.ko driver module. The problem is that this NIC cannot connect at gigabit (1000MBps) speed. In all cases connection works well at 100MBps. Following are the tests I've completed: - Cables tested with cable tester - Cables tested to work at gigabit speed with Realtek and Intel gigabit NICs. - All unmanaged switch ports tested at ggigabit speed with other NICs. - Tried to connect with NetworkManager enabled and disabled. - Tried both dhcp and static connections. - Tried to renegotiate connection with `ethtool -r` both with TSO enabled and disabled. - Tried 3.2.0-23-generic 3.5.0-15-generic3.5.0-17-generic 3.6.0-999-generic kernels from main, xorg-edgers and mainline repos. - Used 'tg3_debug=1' kernel option in grub with the following output: - [0.00] Command line: BOOT_IMAGE=/vmlinuz-3.5.0-17-generic root=UUID=eccabacd-efb2-45b4-b7a6-2f530d50afd3 ro rootflags=subvol=@ tg3_debug=1 i915_enable_rc6=7 i915_enable_fbc=1 lvds_downclock=1 - [0.00] Kernel command line: BOOT_IMAGE=/vmlinuz-3.5.0-17-generic root=UUID=eccabacd-efb2-45b4-b7a6-2f530d50afd3 ro rootflags=subvol=@ tg3_debug=1 i915_enable_rc6=7 i915_enable_fbc=1 lvds_downclock=1 - [5.963136] tg3.c:v3.123 (March 21, 2012) - [5.995781] tg3 mdio bus: probed - [6.005583] tg3 :01:00.0: eth0: Tigon3 [partno(BCM57780) rev 57780001] (PCI Express) MAC address dc:0e:a1:ac:38:d5 - [6.005687] tg3 :01:00.0: eth0: attached PHY driver [Broadcom BCM57780] (mii_bus:phy_addr=100:01) - [6.005790] tg3 :01:00.0: eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] TSOcap[1] - [6.005887] tg3 :01:00.0: eth0: dma_rwctrl[7618] dma_mask[64-bit] - [ 294.987653] tg3 :01:00.0: irq 44 for MSI/MSI-X - [ 295.893224] tg3 :01:00.0: eth0: Link is down - [ 309.887879] tg3 :01:00.0: eth0: Link is up at 100 Mbps, full duplex - [ 309.887886] tg3 :01:00.0: eth0: Flow control is on for TX and on for RX + [0.00] Command line: BOOT_IMAGE=/vmlinuz-3.5.0-17-generic root=UUID=eccabacd-efb2-45b4-b7a6-2f530d50afd3 ro rootflags=subvol=@ tg3_debug=1 i915_enable_rc6=7 i915_enable_fbc=1 lvds_downclock=1 + [0.00] Kernel command line: BOOT_IMAGE=/vmlinuz-3.5.0-17-generic root=UUID=eccabacd-efb2-45b4-b7a6-2f530d50afd3 ro rootflags=subvol=@ tg3_debug=1 i915_enable_rc6=7 i915_enable_fbc=1 lvds_downclock=1 + [5.963136] tg3.c:v3.123 (March 21, 2012) + [5.995781] tg3 mdio bus: probed + [6.005583] tg3 :01:00.0: eth0: Tigon3 [partno(BCM57780) rev 57780001] (PCI Express) MAC address dc:0e:a1:ac:38:d5 + [6.005687] tg3 :01:00.0: eth0: attached PHY driver [Broadcom BCM57780] (mii_bus:phy_addr=100:01) + [6.005790] tg3 :01:00.0: eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] TSOcap[1] + [6.005887] tg3 :01:00.0: eth0: dma_rwctrl[7618] dma_mask[64-bit] + [ 294.987653] tg3 :01:00.0: irq 44 for MSI/MSI-X + [ 295.893224] tg3 :01:00.0: eth0: Link is down + [ 309.887879] tg3 :01:00.0: eth0: Link is up at 100 Mbps, full duplex + [ 309.887886] tg3 :01:00.0: eth0: Flow control is on for TX and on for RX Other distros' forums suggest loading broadcom.ko first; however, this - module is no present.

Thank you Justin, I had figured as much, as this is happening in Windows. However, it seems randomly I am able to connect at 1GBps. So the card CAN do GIgabit speeds. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063038 Title: Broadcom BCM57780 Cannot Connect at Gigabit Speed using tg3 module.

One thing I noticed is that my `ethtool -i eth0` output is different. I've listed your values to the right where the seem to be significant. I'm a little in the dark as to why my `firmware-version` string and `eeprom-access` bool values are different and whether that has any import. # ethtool -i eth0 driver: tg3 version: 3.123 3.121 firmware-version: sb 57780-v3.15 bus-info: :01:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: no yes supports-register-dump: yes Another interesting observation is that `ethtool -s eth0 advertise 0x020` forcing autoneg to select 1000Mbps/Full kills the connection. Do you have any suggestions as to how to debug the rate/duplex autonegotiation? I'm unsure how to proceed to further diagnose this problem.

In the meantime can you send me the output of 1. ethtool iface 2. Reg read of the following registers. You can do this by indirect access for e.g. to read register 0x400. Everything is in hex so don't add a 0x to any number. setpci -s pci bus:pci dev.pci fn 78.l=400 setpci -s pci bus:pci dev.pci fn 80.l Give me the readings for 0x400, 0x404, 0x408, 0x45c, 0x460, all from 0x3600-0x3610, 0x362c, 0x3630. Can you do this for both when it links up in 100Mbit and when you force it to 0x20 and it doesn't link up.

One thing I noticed is that my `ethtool -i eth0` output is different. I've listed your values to the right where the seem to be significant. I'm a little in the dark as to why my `firmware-version` string and `eeprom- access` bool values are different and whether that has any import. # ethtool -i eth0 driver: tg3 version: 3.123 3.121 firmware-version: sb 57780-v3.15 bus-info: :01:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: no yes supports-register-dump: yes Another interesting observation is that `ethtool -s eth0 advertise 0x020` forcing autoneg to select 1000Mbps/Full kills the connection. Do you have any suggestions as to how to debug the rate/duplex autonegotiation? I'm unsure how to proceed to further diagnose this problem. [BTW

Asking it to advertise everything up to 1000Full causes it to actually advertise only up to 100Full.

RE: [Bug 1063038] Re: Broadcom BCM57780 Cannot Connect at Gigabit Speed using tg3 module.
Justin, Sorry, I'd already replied to netdev but found out later it didn't make it. Resending what I sent netdev but did not reach there. Basically I'm not seeing a problem with the 57780 with either RedHat or Ubuntu. So I'm not sure what it could be the problem in your case. Thanks, Nithin. --- Quote --- I don't see a problem linking up with 57780 at gigabit. I tested the latest net kernel (3.6.0) and to make sure it's not ubuntu specific, tested ubuntu 12.04 as well (3.2.0.23-generic). Everything works fine here on my setup.

[Bug 1063038] Re: Broadcom BCM57780 Cannot Connect at Gigabit Speed using tg3 module.
This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug. Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.
