2016-11-24net: phy: broadcom: Allow enabling or disabling of EEEFlorian Fainelli
In preparation for adding support for Wirespeed/downshift, we need to change bcm_phy_eee_enable() to allow enabling or disabling EEE, so make the function take an extra enable/disable boolean parameter and rename it to illustrate it sets EEE, not necessarily just enables it.

2016-11-24net: phy: broadcom: Add support code for downshift/WirespeedFlorian Fainelli

Add support code for retrieving and setting such downshift counters using the recently added ethtool downshift tunables. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

Indicate hardware (or firmware) supports that CQM packet-loss report will be generated based on station kickout algorithm. As of now mac80211 tracks connection loss by missing msdu counts (50) whereas ath10k firmware tracks them by missing ppdus (+ BAR tries).

All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-22marvell: mark mvneta and mvpp2 32-bit onlyArnd Bergmann
Both of these drivers won't work on 64-bit architectures unless they are redesigned, since they store a virtual address pointer in a 32-bit field of the descriptors: drivers/net/ethernet/marvell/mvneta_bm.c: In function 'mvneta_bm_construct': drivers/net/ethernet/marvell/mvneta_bm.c:103:16: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_prs_vlan_init': drivers/net/ethernet/marvell/mvpp2.c:2563:32: error: large integer implicitly truncated to unsigned type [-Werror=overflow] This limits the COMPILE_TEST option for the two drivers again to only build them on 32-bit. This seems nicer than shutting up the warnings, in case we ever actually want to use them on 64-bit, as the warnings indicate which parts of the driver are currently broken there.

2016-11-22mlxsw: reg: Add Management Fan Speed Limit registerJiri Pirko
The MFSL register is used to configure the fan speed event / interrupt notification mechanism. Fan speed threshold are defined for both under-speed and over-speed.

2016-11-22net: dsa: mv88e6xxx: Move g1 stats code in global1.[ch]Andrew Lunn
Move the stats functions which access global 1 registers into global1.c. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-22net: dsa: mv88e6xxx: Implement mv88e6390 get_statsAndrew Lunn
The mv88e6390 uses a different bit to select between bank0 and bank1 of the statistics. So implement an ops function for this, and pass the selector bit to the generic stats read function. Also, the histogram selection has moved for the mv88e6390, so abstract its selection as well. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-22net: dsa: mv88e6xxx: Add stats_get_stats to ops structureAndrew Lunn
Different families have different sets of statistics. Abstract this using a stats_get_stats op. The mv88e6390 needs a different implementation, which will be added later. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-22net: dsa: mv88e6xxx: Add stats_get_sset_count|string to ops structureAndrew Lunn
Different families have different sets of statistics. Abstract this using a stats_get_sset_count and stats_get_strings op. Each stat has a bitmap, and the ops implementer uses a bit map mask to count the statistics which apply for the family, or return the list of strings.

2016-11-22net: dsa: mv88e6xxx: Add mv88e6390 statistics unit initAndrew Lunn
The statistics unit on the mv88e6390 needs the histogram mode to be configured in a different register compared to other devices. Add an ops to do this. Signed-off-by: Andrew Lunn <andrew@lunn.ch> v2: Rename to mv88e6390_g1_stats_set_histogram Move into global1.c Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-22net: dsa: mv88e6xxx: Add mv88e6390 stats snapshot operationAndrew Lunn
The MV88E6390 has a control register for what the histogram statistics actually contain. This means the stat_snapshot method should not set this information. So implement the 6390 stats_snapshot function without these bits. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-22net: dsa: mv88e6xxx: Add comment about family a device belongs toAndrew Lunn
Knowing the family of device belongs to helps with picking the ops implementation which is appropriate to the device. So add a comment to each structure of ops. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-11-22net: dsa: mv88e6xxx: Abstract stats_snapshot into ops structureAndrew Lunn
Taking a stats snapshot differs between same families. Abstract this into an ops member. At the same time, move the code into global1.[ch], since the registers are in the global1 range. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
