2014-09-19Merge branch 'master' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-09-18 This series contains updates to ixgbe and ixgbevf. Ethan Zhao cleans up ixgbe and ixgbevf by removing bd_number from the adapter struct because it is not longer useful. Mark fixes ixgbe where if a hardware transmit timestamp is requested, an uninitialized workqueue entry may be scheduled. Added a check for a PTP clock to avoid that. Jacob provides a number of cleanups for ixgbe. Since we may call ixgbe_acquire_msix_vectors() prior to registering our netdevice, we should not use the netdevice specific printk and use e_dev_warn() instead. Similar to how ixgbevf handles acquiring MSI-X vectors, we can return an error code instead of relying on the flag being set. This makes it more clear that we have failed to setup MSI-X mode and will make it easier to consolidate MSI-X related code into a single function. In the case of disabling DCB, it is not an error since we still can function, we just have to let the user know. So use e_dev_warn() instead of e_err(). Added warnings for other features that are disabled when we are without MSI-X support. Cleanup flags that are no longer used or needed. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-19net/mlx4_en: Add mlx4_en_get_cqe helperIdo Shamay
This function derives the base address of the CQE from the CQE size, and calculates the real CQE context segment in it from the factor (this is like before). Before this change the code used the factor to calculate the base address of the CQE as well. The factor indicates in which segment of the cqe stride the cqe information is located. For 32-byte strides, the segment is 0, and for 64 byte strides, the segment is 1 (bytes 32..63). Using the factor was ok as long as we had only 32 and 64 byte strides. However, with larger strides, the factor is zero, and so cannot be used to calculate the base of the CQE. The helper uses the same method of CQE buffer pulling made by all other components that reads the CQE buffer (mlx4_ib driver and libmlx4).

2014-09-19net/mlx4_core: Enable CQE/EQE stride supportIdo Shamay
This feature is intended for archs having cache line larger then 64B. Since our CQE/EQEs are generally 64B in those systems, HW will write twice to the same cache line consecutively, causing pipe locks due to he hazard prevention mechanism. For elements in a cyclic buffer, writes are consecutive, so entries smaller than a cache line should be avoided, especially if they are written at a high rate. Reduce consecutive writes to same cache line in CQs/EQs, by allowing the driver to increase the distance between entries so that each will reside in a different cache line. Until the introduction of this feature, there were two types of CQE/EQE: 1. 32B stride and context in the [0-31] segment 2. 64B stride and context in the [32-63] segment This feature introduces two additional types: 3. 128B stride and context in the [0-31] segment (128B cache line) 4. 256B stride and context in the [0-31] segment (256B cache line) Modify the mlx4_core driver to query the device for the CQE/EQE cache line stride capability and to enable that capability when the host cache line size is larger than 64 bytes (supported cache lines are 128B and 256B). The mlx4 IB driver and libmlx4 need not be aware of this change. The PF context behaviour is changed to require this change in VF drivers running on such archs.

The integrated BCM7xxx PHY contains no useful revision information in its MII_PHYSID2 bits 3:0, that information is instead contained in the GENET hardware block.

2014-09-19net: fec: Workaround for imx6sx enet tx hang when enable three queuesFugang Duan
When enable three queues on imx6sx enet, and then do tx performance test with iperf tool, after some time running, tx hang. Found that: If uDMA is running, software set TDAR may cause tx hang. If uDMA is in idle, software set TDAR don't cause tx hang. There is a TDAR race condition for mutliQ when the software sets TDAR and the UDMA clears TDAR simultaneously or in a small window (2-4 cycles). This will cause the udma_tx and udma_tx_arbiter state machines to hang. The issue exist at i.MX6SX enet IP. So, the Workaround is checking TDAR status four time, if TDAR cleared by hardware and then write TDAR, otherwise don't set TDAR. The patch is only one Workaround for the issue ERR007885.

i.MX6 SX change FEC alignment requirement. i.MX6 SX change internal bus from AHB to AXI. It require RX buffer must be 64 bytes alignment. And remove TX buffer alignment requirement.

2014-09-13net: fec: add enet-avb IP supportFrank Li
i.MX6SX Enet-AVB support 3 tx queues, 3 rx queues. For tx queues: ring 0 -> best effort ring 1 -> Class A ring 2 -> Class B For rx queues: ring 0 -> best effort ring 1 -> receive VLAN packet with classification match ring 2 -> receive VLAN packet with classification match Add enet-avb IP multiqueue support for the driver.

2014-09-13net:fec: Disable enet-avb MAC instead of reset MACFugang Duan
For i.MX6SX enet use AXI bus, reset MAC will make system bus dead if ENET-AXI bus has pending access (AHB bus should not have such issue). So, disable enet with AVB MAC instead of reset MAC itself.
