2018-09-19net: hns3: Remove packet statistics of publicPeng Li2-418/+0
All pf have permission to read packet statistics of public in hardware, but the read operation will clear registers which cause statistical inaccuracy. This patch removes all packet statistics of public.

2018-09-19net: phy: phylink: ensure the carrier is off when starting phylinkAntoine Tenart1-0/+3
Phylink made an assumption about the carrier state being down when calling phylink_start(). If this assumption isn't satisfied, the internal phylink state could misbehave and a net device could end up not being functional. This patch fixes this by explicitly calling netif_carrier_off() in phylink_start().

2018-09-19net: mvpp2: rename mvpp2_percpu function to mvpp2_threadAntoine Tenart1-47/+47
As the mvpp2_percpu_read/write/... functions aren't really per-cpu but per s/w thread, rename them to include 'thread' instead of 'percpu'. This is a cosmetic patch. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-19net: mvpp2: handle cases where more CPUs are available than s/w threadsAntoine Tenart2-54/+112
The Marvell PPv2 network controller has 9 internal threads. The driver works fine when there are less CPUs available than threads. This isn't true if more CPUs are available. As this is a valid use case, handle this particular case. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-19net: mvpp2: map the CPUs to threadsAntoine Tenart2-40/+55
This patch maps all uses of the CPU to threads. All this_cpu calls are replaced, and all smp_processor_id() calls are wrapped into the indirection. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-19net: mvpp2: do not use the CPU number to access the per-thread registersAntoine Tenart1-81/+88

2018-09-19net: mvpp2: make mvpp2_read_relaxed staticAntoine Tenart2-3/+1

2018-09-19net: mvpp2: make the per-cpu helpers staticAntoine Tenart2-10/+3

2018-09-19net: mvpp2: cpu should always be unsignedAntoine Tenart2-30/+35
Updates the PPv2 driver so that all CPU variables are unsigned, as it makes no sense to have a negative CPU number. This patch is cosmetic. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-19net: mvpp2: fix the number of queues per cpu for PPv2.2Antoine Tenart2-4/+6
The Marvell PPv2.2 engine only has 8 Rx queues per CPU, while PPv2.1 has 16 of them. This patch updates the code so that the Rx queues mask width is selected given the version of the network controller used.

2018-09-19net: mvpp2: do not update the queue mode while probingAntoine Tenart1-8/+9
This patch updates the probing function so that the queue mode isn't updated while probing, as the driver would silently end up using a configuration not wanted by the user. The patch adds an extra check to validate the chosen queue mode instead, and the driver will fail to probe if the configuration is invalid.

2018-09-19net: mvpp2: rename the IRQs to match the hardwareAntoine Tenart2-15/+46
This patch renames the IRQs in the Marvell PPv2 driver as their current names match the way they are used in software. But this will change in the future, and those IRQs have nothing to do with Rx/Tx interrupts (this can be configured). The new binding also describe more interrupts as some where left out. The old binding support is kept for backward compatibility. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-19net: mvpp2: increase the number of s/w threads to 9Antoine Tenart1-1/+1
This patch sets the number of s/w threads to 9, its maximum value, instead of 8. This is not a fix as only 4 of the s/w threads were used so far, but more could be used in the future. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-09-19mt76: use a per rx queue page fragment cacheFelix Fietkau3-8/+20
Using the NAPI or netdev frag cache along with other drivers can lead to 32 KiB pages being held for a long time, despite only being used for very few page fragments. This can happen if the driver grabs one or two fragments for rx ring refill, while other drivers use (and free up) the remaining fragments. The 32 KiB higher-order page can only be freed once all users have freed their fragments. Depending on the traffic patterns, this can waste a lot of memory and look a lot like a memory leak.
