2014-04-26i40e: fix Timesync Tx interrupt handler codeJacob Keller
This patch fixes the PTP Tx timestamp interrupt handler. The original code misinterpreted the interrupt handler design. We were clearing the ena_mask bit for the Timesync interrupts. This is done to indicate that the interrupt will be handled in a scheduled work item (instead of immediately) and that work item is responsible for re-enabling the interrupts. However, the Tx timestamp was being handled immediately and nothing was ever re-enabling it. This resulted in a single interrupt working for the life of the driver. This patch fixes the issue by instead clearing the bit from icr0 which is used to indicate that the interrupt was immediately handled and can be re-enabled right away. This patch also clears up a related issue due to writing the PRTTSYN_STAT_0 register, which was unintentionally clearing the cause bits for Timesync interrupts.

This patch works around a recently discovered unaligned receive dma problem with the Altera SGMDA. The Altera SGDMA component cannot be configured to DMA data to unaligned addresses for receive packet operations from the Triple Speed Ethernet component because of a potential data transfer corruption that can occur. This patch addresses this issue by utilizing the shift 16 bits feature of the Altera Triple Speed Ethernet component and modifying the receive buffer physical addresses accordingly such that the target receive DMA address is always aligned on a 32-bit boundary.

2014-04-26bnx2x: Fix vlan credit issues for VFsYuval Mintz
Starting with commit 2dc33bbc "bnx2x: Remove the sriov VFOP mechanism", the bnx2x started enforcing vlan credits for all vlan configurations. This exposed 2 issues: - Vlan credits are not returned once a VF is removed; this causes a leak of credits, and eventually will lead to VFs with no vlan credits. - A vlan credit must be set aside for the Hypervisor to use, and should not be visible to the VF. Although linux VFs at the moment do not support vlan configuration [from the VF side] which causes them to be resilient to this sort of issue, Windows VF over linux hypervisors might fail to load as the vlan credits become depleted.

2014-04-24can: c_can: Work around C_CAN RX wreckageThomas Gleixner
Alexander reported that the new optimized handling of the RX fifo causes random packet loss on Intel PCH C_CAN hardware. After a few fruitless debugging sessions I got hold of a PCH (eg20t) afflicted system. That machine does not have the CAN interface wired up, but it was possible to reproduce the issue with the HW loopback mode. As Alexander observed correctly, clearing the NewDat flag along with reading out the message buffer causes that issue on C_CAN, while D_CAN handles that correctly. Instead of restoring the original message buffer handling horror the following workaround solves the issue: transfer buffer to IF without clearing the NewDat handle the message clear NewDat bit That's similar to the original code but conditional for C_CAN. I really wonder why all user manuals (C_CAN, Intel PCH and some more) recommend to clear the NewDat bit right away. The knows it all Oracle operated by Gurgle does not unearth any useful information either. I simply cannot believe that we are the first to uncover that HW issue.

2014-04-24can: c_can: Disable rx split as workaroundThomas Gleixner
The RX buffer split causes packet loss in the hardware: What happens is: RX Packet 1 --> message buffer 1 (newdat bit is not cleared) RX Packet 2 --> message buffer 2 (newdat bit is not cleared) RX Packet 3 --> message buffer 3 (newdat bit is not cleared) RX Packet 4 --> message buffer 4 (newdat bit is not cleared) RX Packet 5 --> message buffer 5 (newdat bit is not cleared) RX Packet 6 --> message buffer 6 (newdat bit is not cleared) RX Packet 7 --> message buffer 7 (newdat bit is not cleared) RX Packet 8 --> message buffer 8 (newdat bit is not cleared) Clear newdat bit in message buffer 1 Clear newdat bit in message buffer 2 Clear newdat bit in message buffer 3 Clear newdat bit in message buffer 4 Clear newdat bit in message buffer 5 Clear newdat bit in message buffer 6 Clear newdat bit in message buffer 7 Clear newdat bit in message buffer 8 Now if during that clearing of newdat bits, a new message comes in, the HW gets confused and drops it. It does not matter how many of them you clear. I put a delay between clear of buffer 1 and buffer 2 which was long enough that the message should have been queued either in buffer 1 or buffer 9. But it did not show up anywhere. The next message ended up in buffer 1. So the hardware lost a packet of course without telling it via one of the error handlers. That does not happen on all clear newdat bit events. I see one of 10k packets dropped in the scenario which allows us to reproduce. But the trace looks always the same. Not splitting the RX Buffer avoids the packet loss but can cause reordering. It's hard to trigger, but it CAN happen. With that mode we use the HW as it was probably designed for. We read from the buffer 1 upwards and clear the buffer as we get the message. That's how all microcontrollers use it. So I assume that the way we handle the buffers was never really tested. According to the public documentation it should just work :) Let the user decide which evil is the lesser one.

2014-04-24can: c_can: Get rid of pointless interruptsThomas Gleixner
The driver handles pointlessly TWO interrupts per packet. The reason is that it enables the status interrupt which fires for each rx and tx packet and it enables the per message object interrupts as well. The status interrupt merily acks or in case of D_CAN ignores the TX/RX state and then the message object interrupt fires. The message objects interrupts are only useful if all message objects have hardware filters activated. But we don't have that and its not simple to implement in that driver without rewriting it completely. So we can ditch the message object interrupts and handle the RX/TX right away from the status interrupt. Instead of TWO we handle ONE. Note: We must keep the TXIE/RXIE bits in the message buffers because the status interrupt alone is not reliable enough in corner cases. If we ever have the need for HW filtering, then this code needs a complete overhaul and we can think about it then. For now we prefer a lower interrupt load.

But that happens before napi_enable() and that means that an interrupt which comes in will disable interrupts again and call napi_schedule, which ignores the request and the later napi_enable() is not making thinks work either.

2014-04-23net/phy: micrel: fix bugged test on device tree loading for ksz9021Hubert Chaumette
In ksz9021_load_values_from_of() val2 to val4 aren't tested against their initialization value. This causes the test to always succeed, and this value to be used as if it was loaded from the devicetree instead of being ignored, in case of a missing/invalid property in the ethernet OF device node. As a result, the value "0" is written to the relevant registers. Change the conditions to test against the right initialization value.
