| | | | | | | | | | | | | This updates the bonding driver to support v2.6.27-rc3 enhancements (b11f8d8c aka. "ethtool: Expand ethtool_cmd.speed to 32 bits") which allow to encode the Mbps link speed on 32-bits (Max 4 Pbps) instead of 16 (Max 65536 Mbps).

* net-bonding: Fix minor/cosmetic type inconsistenciesDavid Decotigny2011-04-15
| | | | | | | | | | | | | The __get_link_speed() function returns a u16 value which was stored in a u32 local variable. This patch uses the return value directly, thus fixing that minor type consistency.

* ethtool: allow custom interval for physical identificationAllan, Bruce W2011-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ixgbe: DCB, misallocated packet buffer size with X540 deviceJohn Fastabend2011-04-13
| | | | | | | | | | | | | | | | | | The X540 device has a smaller packet buffer but the DCB configuration never took this into account. Under stress this can result in the DMA engine hanging and TX Unit hang occurring to reset the device. This patch reworks the packet buffer allocation routine used for DCB on 82599 and X540 devices to account for RX packet buffer sizes. This fixes the immediate hang. We should consolidate the various hardware specific routines for configuring features into a single routine. This will make it much harder to miss feature cases like this.

* e1000e: If ASPM L0s needs to be disabled, do it prior to enabling deviceBruce Allan2011-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a patch from Naga Chumbalkar <nagananda.chumbalkar@hp.com>: If ASPM L0s needs to be disabled due to HW errata, do it prior to "enabling" the device. This way if the kernel ever defaults its aspm_policy to POLICY_POWERSAVE, then the e1000e driver will get a chance to disable ASPM on the misbehaving device *prior* to calling pci_enable_device_mem(). This will be useful in situations where the BIOS indicates ASPM support on the server by clearing the ACPI FADT "ASPM Controls" bit. Note: The kernel (2.6.38) currently uses the BIOS "default" as its aspm_policy. However, Linux distros can diverge from that and set the default to "powersave". v2: o cleanup namespace pollution of e1000e_disable_aspm(), o fix type and initialization of the new aspm_disable_flag in a few functions, and o redefine FLAG2_DISABLE_ASPM_L0S to the first unused bit in adapter->flags2.
