2015-12-10Bluetooth: btintel: Create common Intel Version Read functionLoic Poulain
The Intel Version Read command is used to retrieve information about hardware and firmware version/revision of Intel Bluetooth controllers. This is an Intel generic command used in USB and UART drivers. Signed-off-by: Loic Poulain <loic.poulain@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-12-10Bluetooth: btintel: Add manufacturing enter/exit helpersLoic Poulain
Older Intel controllers need to enter manufacturing mode to perform some vendor specific operations (patching, configuration...). Add enter/exit manufaturing methods and refactor existing manufacturing code. Exit can be configured to perform a reset. Reset can be performed either with patches activated or deactivated.

2015-12-06net/mlx4_core: Support the HA mode for SRIOV VFs tooMoni Shoua
When the mlx4 driver runs in HA mode, and all VFs are single ported ones, we make their single port Highly-Available. This is done by taking advantage of the HA mode properties (following bonding changes with programming the port V2P map, etc) and adding the missing parts which are unique to SRIOV such as mirroring VF steering rules on both ports. Due to limits on the MAC and VLAN table this mode is enabled only when number of total VFs is under 64.

2015-12-06IB/mlx4: Use the VF base-port when demuxing mad from wireOr Gerlitz
Under HA mode, it's possible that the VF registered its GID (and expects to get mads through the PV scheme) on a port which is different from the one this mad arrived on, due to HA fail over. Therefore, if the gid is not matched on the port that the packet arrived on, check for a match on the other port if HA mode is active -- and if a match is found on the other port, continue processing the mad using that other port.

2015-12-06net/mlx4_core: Keep VLAN/MAC tables mirrored in multifunc HA modeMoni Shoua
Due to HW limitations, indexes to MAC and VLAN tables are always taken from the table of the actual port. So, if a resource holds an index to a table, it may refer to different values during the lifetime of the resource, unless the tables are mirrored. Also, even when driver is not in HA mode the policy of allocating an index to these tables is such to make sure, as much as possible, that when the time comes the mirroring will be successful. This means that in multifunction mode the allocation of a free index in a port's table tries to make sure that the same index in the other's port table is also free.

2015-12-06net/mlx4_core: Support mirroring VF DMFS rules on both portsMoni Shoua
Under HA mode, steering rules set by VFs should be mirrored on both ports of the device so packets will be accepted no matter on which port they arrived. Since getting into HA mode is done dynamically when the user bonds mlx4 Ethernet netdevs, we keep hold of the VF DMFS rule mbox with the port value flipped (1->2,2->1) and execute the mirroring when getting into HA mode. Later, when going out of HA mode, we unset the mirrored rules. In that context note that mirrored rules cannot be removed explicitly.

2015-12-05fm10k: Add support for ITR scaling based on PCIe link speedJacob Keller
The Intel Ethernet Switch FM10000 Host Interface interrupt throttle timers are based on the PCIe link speed. Because of this, the value being programmed into the ITR registers must be scaled accordingly. For the PF, this is as simple as reading the PCIe link speed and storing the result. However, in the case of SR-IOV, the VF's interrupt throttle timers are based on the link speed of the PF. However, the VF is unable to get the link speed information from its configuration space, so the PF must inform it of what scale to use. Rather than pass this scale via mailbox message, take advantage of unused bits in the TDLEN register to pass the scale. It is the responsibility of the PF to program this for the VF while setting up the VF queues and the responsibility of the VF to get the information accordingly. This is preferable because it allows the VF to set up the interrupts properly during initialization and matches how the MAC address is passed in the TDBAL/TDBAH registers. Since we're modifying fm10k_type.h, we may as well also update the copyright year.

2015-12-05fm10k: add statistics for actual DWORD count of mbmem mailboxJacob Keller
A previous bug was uncovered by addition of a debug stat to indicate the actual number of DWORDS we pulled from the mbmem. It turned out this was not the same as the tx_dwords counter. While the previous bug fix should have corrected this in all cases, add some debug stats that count the number of DWORDs pushed or pulled from the mbmem. A future debugger may take advantage of this statistic for debugging purposes. Since we're modifying fm10k_mbx.h, update the copyright year as well.

2015-12-05fm10k: Correct typecast in fm10k_update_xc_addr_pfJacob Keller
Since the resultant data type of the mac_update.mac_upper field is u16, it does not make sense to typecast u8 variables to u32 first. Since we're modifying fm10k_pf.c, also update the copyright year.
