2013-08-21sfc: Fix lookup of default RX MAC filters when steered using ethtoolBen Hutchings1-1/+1
commit 385904f819e3 ('sfc: Don't use efx_filter_{build,hash,increment}() for default MAC filters') used the wrong name to find the index of default RX MAC filters at insertion/ update time. This could result in memory corruption and would in any case silently fail to update the filter. Signed-off-by: Ben Hutchings <[email protected]>
2013-08-20net: cpsw: Add support for wake-on-lan for cpswMatus Ujhelyi1-0/+25
Some phy's can be configured to enable wake on lan (e.g. at803x or marvell 88E1318S). There is no way how to enable wol on CPSW with such connected phys. This patch adds this support. It is provided by calling the phy's related code. Tested on board with at8030x connected phy. Wol interrupt line is connected to GPIO0 on am335x.

2013-08-20pch_gbe: ethtool cannot change parameters when link is downAnders Larsen1-0/+1
When attempting to change e.g. the advertising mask when the link is down ecmd->speed is -1 causing mii_ethtool_sset() to bail out. This bug bit when connecting to a gigabit switch through a 4-pin (industrial) cable, since link negotiation would not complete (both endpoints claimed to be gigabit-capable, but this is not possible with only 4 pins). Any attempt to fix this by setting autonegation to not offer 1000Mbps failed as the setting would not be accepted while the link was still down... Set ecmd->speed to SPEED_1000 to satisfy mii_ethtool_sset() (the actual value of ecmd->speed doesn't matter as long as it is valid, since a re-negotation is forced afterwards).

2013-08-20bnx2x: set VF DMAE when first function has 0 supported VFsAriel Elior1-5/+2
There are possible HW configurations in which PFs will have SR-IOV capability but will have Max VFs set to 0 - this happens when there are Multi-Function devices where the VFs are allocated to only some of the PFs. DMAE is configured to support VFs only if the configuring PF has supported VFs. In case the first PF to be loaded will be one without supported VFs, it will not configure DMAE to the VF-supporting mode. When VFs of other PFs will be loaded later on, they will not be able to communicate with their PF. This changes the requirement for configuring DMAE for VF-supporting mode; If the device has SR-IOV capabilities there must be some PF that has max supported VFs > 0, thus it will configure the DMAE for supporting VFs.

2013-08-20bnx2x: Protect against VFs' ndos when SR-IOV is disabledAriel Elior1-18/+31
Since SR-IOV can be activated dynamically and iproute2 can be called asynchronously, the various callbacks need a robust sanity check before attempting to access the SR-IOV database and members since there are numerous states in which it can find the driver (e.g., PF is down, sriov was not enabled yet, VF is down, etc.). In many of the states the callback result will be null pointer dereference.

2013-08-20bnx2x: Change DCB context handlingDmitry Kravkov4-8/+43
After notification that DCBX configuration has ended arrived to the driver, the driver configured the FW/HW in sleepless context. As a result, it was possible to reach a race (mostly with CNIC registration) in which the configuration will return a timeout, failing to set the DCBX results correctly. This patch moves the configuration following the DCBX end into the slowpath RTNL task (i.e., sleepless context protected by the RTNL lock), allowing the configuration to cope with such races.

Since commit 3deb816 "bnx2x: Add a periodic task for link PHY events" link state changes can be detected not only via the attention flow but also from the periodic task.

2013-08-15net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer4-35/+29
In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.
