* tg3: Fix crc errors on jumbo frame receiveNithin Nayak Sujir2013-02-141-21/+33
| | | | | | | | | | | | | | [ Upstream commit daf3ec688e057f6060fb9bb0819feac7a8bbf45c ] TG3_PHY_AUXCTL_SMDSP_ENABLE/DISABLE macros do a blind write to the phy auxiliary control register and overwrite the EXT_PKT_LEN (bit 14) resulting in intermittent crc errors on jumbo frames with some link partners.

* tg3: Avoid null pointer dereference in tg3_interrupt in netconsole modeNithin Nayak Sujir2013-02-141-0/+4
| | | | | | | | | | | | | | | [ Upstream commit 9c13cb8bb477a83b9a3c9e5a5478a4e21294a760 ] When netconsole is enabled, logging messages generated during tg3_open can result in a null pointer dereference for the uninitialized tg3 status block. Use the irq_sync flag to disable polling in the early stages. irq_sync is cleared when the driver is enabling interrupts after all initialization is completed.

* tg3: Fix TSO CAP for 5704 devs w / ASF enabledMatt Carlson2012-10-131-2/+12
| | | | | | | | | | | | | | | | | | | | | | [ Upstream commit cf9ecf4b631f649a964fa611f1a5e8874f2a76db ] On the earliest TSO capable devices, TSO was accomplished through firmware. The TSO cannot coexist with ASF management firmware though. The tg3 driver determines whether or not ASF is enabled by calling tg3_get_eeprom_hw_cfg(), which checks a particular bit of NIC memory. Commit dabc5c670d3f86d15ee4f42ab38ec5bd2682487d, entitled "tg3: Move TSO_CAPABLE assignment", accidentally moved the code that determines TSO capabilities earlier than the call to tg3_get_eeprom_hw_cfg(). As a consequence, the driver was attempting to determine TSO capabilities before it had all the data it needed to make the decision. This patch fixes the problem by revisiting and reevaluating the decision after tg3_get_eeprom_hw_cfg() is called.

| | | | | | | | | | | | | | | [ Upstream commit f891ea1634ce41f5f47ae40d8594809f4cd2ca66 ] When RSS is enabled, interrupt vector 0 does not receive any rx traffic. The rx producer index fields for vector 0's status block should be considered reserved in this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When tg3 was new, phy accesses through ioctl were allowable at any time. Then, the driver started shutting down the phy when the device was closed. Phy accesses would be allowed when the driver first attached to the device, but then would be forbidden after the device had been up'd and down'd. After that, management firmware made it illegal to access the phy unless the driver "owned" the device. Now that most firmware is being moved over to the APE, it is less clear when phy accesses are safe. While it is possible to attempt to identify these conditions and code the driver to navigate through the pitfalls, it could be perplexing to the admin why phy accesses work in some cases and not others. This patch brings some uniformity to the problem by only allowing phy accesses while the driver has control of the device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The oldest tg3 devices had large rx producer ring BD caches. Back then, it made sense to make the BD cache replenish threshold only a function of the number of rx buffers posted by the driver. Since then, the BD cache sizes have shrunk to 25% of their original size and, in some cases, the ring sizes have quadrupled in size. Under such conditions, static BD cache replenish thresholds no longer match the hardware constraints. This patch attempts to factor in the BD cache size into the bd cache replenish strategy, taking the existing hardware bugs into account.

* | tg3: Workaround rx_discards stat bugMatt Carlson2011-04-211-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | The 5717, 5718, 5719 A0, and 5720 A0 has a bug where the rx_discards statistic counter will increment when dropping unwanted multicast frames. This patch works around the problem by attempting to recreate the data using other means. The resulting value will not be accurate, but it can still serve as a problem indicator.

* | ethtool: allow custom interval for physical identificationAllan, Bruce W2011-04-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When physical identification of an adapter is done by toggling the mechanism on and off through software utilizing the set_phys_id operation, it is done with a fixed duration for both on and off states. Some drivers may want to set a custom duration for the on/off intervals. This patch changes the API so the return code from the driver's entry point when it is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to cycle the on/off states, and updates the drivers that have already been converted to use the new set_phys_id and use the synchronous method for identifying an adapter. The physical identification frequency set in the updated drivers is based on how it was done prior to the introduction of set_phys_id. Compile tested only. Also fixes a compiler warning in sfc. v2: drivers do not return -EINVAL for ETHOOL_ID_ACTIVE v3: fold patchset into single patch and cleanup per Ben's feedback Signed-off-by: Bruce Allan <bruce.w.allan@intel.com> Cc: Ben Hutchings <bhutchings@solarflare.com> Cc: Sathya Perla <sathya.perla@emulex.com> Cc: Subbu Seetharaman <subbu.seetharaman@emulex.com> Cc: Ajit Khaparde <ajit.khaparde@emulex.com> Cc: Michael Chan <mchan@broadcom.com> Cc: Eilon Greenstein <eilong@broadcom.com> Cc: Divy Le Ray <divy@chelsio.com> Cc: Don Fry <pcnet32@frontier.com> Cc: Jon Mason <jdmason@kudzu.us> Cc: Solarflare linux maintainers <linux-net-drivers@solarflare.com> Cc: Steve Hodgson <shodgson@solarflare.com> Cc: Stephen Hemminger <shemminger@linux-foundation.org> Cc: Matt Carlson <mcarlson@broadcom.com> Acked-by: Jon Mason <jdmason@kudzu.us> Acked-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

* | tg3: Add support for extended VPD blocksMatt Carlson2011-04-131-44/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | In some devices, the VPD block is relocated to a different area in NVRAM. The original location can still contain old, but still valid VPD data. This patch changes the code to look for an extended VPD block in NVRAM. If one is found, that block is used for all VPD operations instead.
