tg3: prevent ifup/ifdown during PCI error recovery

2014-09-02T20:02:19Z

The patch fixes race conditions between PCI error recovery callbacks and potential ifup/ifdown. First, if ifup (tg3_open) is called between tg3_io_error_detected() and tg3_io_resume() then tp->timer is armed twice before expiry. Once during tg3_open() and again during tg3_io_resume(). This results in BUG at kernel/time/timer.c:945. Second, if ifdown (tg3_close) is called between tg3_io_error_detected() and tg3_io_resume() then tg3_napi_disable() is called twice without a tg3_napi_enable between. Once during tg3_io_error_detected() and again during tg3_close(). The tg3_io_resume() then hangs on rtnl_lock(). v2: Added logging messages per Prashant's request Cc: Prashant Sreedharan Cc: Michael Chan Signed-off-by: Ivan Vecera Acked-by: Prashant Sreedharan Signed-off-by: David S.

tg3: Don't check undefined error bits in RXBD

2014-02-28T22:16:16Z

Redefine the RXD_ERR_MASK to include only relevant error bits. This fixes a customer reported issue of randomly dropping packets on the 5719. Signed-off-by: Michael Chan Signed-off-by: David S. Miller

tg3: Poll cpmu link state on APE + ASF enabled devices

2014-01-04T01:59:52Z

On ASF enabled devices where the mgmt firmware runs on the application processing engine, there is a race between the tg3 driver processing a link change event and the ASF firmware clearing the link changed bit in the EMAC status register. This leads to link notifications to the driver sometimes getting lost. Poll the CPMU link state as a backup for the normal interrupt path update if ASF is enabled.

tg3: Set the MAC clock to the fastest speed during boot code load

2014-01-04T01:59:52Z

On the 5717, 5718 and 5719 devices, the bootcode runs slower when any port doesn't have a link due to clock speed slowing down as part of the link-aware feature. This leads to the driver timing out waiting for the bootcode signature. This patch overrides the clock policy to the highest frequency just before reset and restores it after the bootcode is up.

tg3: Fix bit definition for the nvram Auto Power Down setting

tg3: Add flag to disable 1G Half Duplex advertisement

2013-12-06T20:10:53Z

Some link partners have issues if the non-standard 1G half duplex is advertised. This patch adds support for an nvram setting to disable the advertisement. Signed-off-by: Nithin Nayak Sujir Signed-off-by: Michael Chan Signed-off-by: David S. Miller

tg3: Add support for new 577xx device ids

2013-09-21T18:04:52Z

This patch adds support for 57764, 57765, 57787, 57782 and 57786 devices. Signed-off-by: Nithin Nayak Sujir Signed-off-by: Michael Chan Signed-off-by: David S. Miller

tg3: Use pci_dev pm_cap

2013-09-14T00:13:00Z

Use the already existing pm_cap variable in struct pci_dev for determining the power management offset. This saves the driver from having to keep track of an extra variable. Signed-off-by: Jon Mason Cc: Nithin Nayak Sujir Cc: Michael Chan Signed-off-by: David S. Miller

tg3: Fix UDP fragments treated as RMCP

2013-07-30T06:38:52Z

The 5762 devices sometimes incorrectly treat udp fragments as RMCP packets and route to the APE. This patch sets the RX_MODE_IPV4_FRAG_FIX bit for these devices which enables the proper behaviour. Signed-off-by: Nithin Nayak Sujir Signed-off-by: Michael Chan Signed-off-by: David S. Miller
