2015-01-16i40e: use same check for Rx hang as for Rx timestampsJacob Keller
It's possible that the user configured only Tx hardware timestamping, and thus we might be receiving PTP traffic which we timestamp but which software never reads. In this case we don't want to check for Rx timestamp hang, because we already know that software won't be handling them. Thus, we add the same check against pf->ptp_rx as we have in the Rx timestamp code path.

2015-01-16net: davinci_emac: Fix hangs with interruptsTony Lindgren
On davinci_emac, we have pulse interrupts. This means that we need to clear the EOI bits when disabling interrupts as otherwise the interrupts keep happening. And we also need to not clear the EOI bits again when enabling the interrupts as otherwise we will get tons of: unexpected IRQ trap at vector 00 These errors almost certainly mean that the omap-intc.c is signaling a spurious interrupt with the reserved irq 127 as we've seen earlier on omap3. Let's fix the issue by clearing the EOI bits when disabling the interrupts. Let's also keep the comment for "Rx Threshold and Misc interrupts are not enabled" for both enable and disable so people are aware of this when potentially adding more support. Note that eventually we should handle the RX and TX interrupts separately like cpsw is now doing. However, so far I have not seen any issues with this based on my testing, so it seems to behave a little different compared to the cpsw that had a similar issue.

2015-01-14net: fec: fix MDIO bus assignement for dual fec SoC'sStefan Agner
On i.MX28, the MDIO bus is shared between the two FEC instances. The driver makes sure that the second FEC uses the MDIO bus of the first FEC. This is done conditionally if FEC_QUIRK_ENET_MAC is set. However, in newer designs, such as Vybrid or i.MX6SX, each FEC MAC has its own MDIO bus. Simply removing the quirk FEC_QUIRK_ENET_MAC is not an option since other logic, triggered by this quirk, is still needed. Furthermore, there are board designs which use the same MDIO bus for both PHY's even though the second bus would be available on the SoC side. Such layout are popular since it saves pins on SoC side. Due to the above quirk, those boards currently do work fine. The boards in the mainline tree with such a layout are: - Freescale Vybrid Tower with TWR-SER2 (vf610-twr.dts) - Freescale i.MX6 SoloX SDB Board (imx6sx-sdb.dts) This patch adds a new quirk FEC_QUIRK_SINGLE_MDIO for i.MX28, which makes sure that the MDIO bus of the first FEC is used in any case. However, the boards above do have a SoC with a MDIO bus for each FEC instance. But the PHY's are not connected in a 1:1 configuration. A proper device tree description is needed to allow the driver to figure out where to find its PHY. This patch fixes that shortcoming by adding a MDIO bus child node to the first FEC instance, along with the two PHY's on that bus, and making use of the phy-handle property to add a reference to the PHY's.

This change is to help improve at-a-glace knowledge of the purpose of the various Cadence MACB/GEM registers. Comments are more helpful for human readability than short acronyms. Describe various #define varibles Cadence MACB/GEM registers as documented in Xilinix's "Zynq-7000 All Programmable SoC TechnicalReference Manual, v1.9.1 (UG-585)" Signed-off-by: Xander Huff <xander.huff@ni.com> Signed-off-by: David S.

2015-01-13net: rename vlan_tx_* helpers since "tx" is misleading thereJiri Pirko
The same macros are used for rx as well. So rename it. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-01-13sunvnet: fix rx packet length check to allow for TSODavid L Stevens
This patch fixes the rx packet length check in the sunvnet driver to allow for a TSO max packet length greater than the LDC channel negotiated MTU. These are negotiated separately and there is no requirement that port->tsolen be less than port->rmtu, but if it isn't, it'll drop packets with rx length errors.

2015-01-13mlx5: avoid build warnings on 32-bitArnd Bergmann
The mlx5 driver passes a string pointer in through a 'u64' variable, which on 32-bit machines causes a build warning: drivers/net/ethernet/mellanox/mlx5/core/debugfs.c: In function 'qp_read_field': drivers/net/ethernet/mellanox/mlx5/core/debugfs.c:303:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] The code is in fact safe, so we can shut up the warning by adding extra type casts.

2015-01-13rocker: fix harmless warning on 32-bit machinesArnd Bergmann
The rocker driver tries to assign a pointer to a 64-bit integer and then back to a pointer. This is safe on all architectures, but causes a compiler warning when pointers are shorter than 64-bit: rocker/rocker.c: In function 'rocker_desc_cookie_ptr_get': rocker/rocker.c:809:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] return (void *) desc_info->desc->cookie; ^ This adds another cast to uintptr_t to tell the compiler that it's safe.

2015-01-13drivers: net: cpsw: fix multicast flush in dual emac modeMugunthan V N
Since ALE table is a common resource for both the interfaces in Dual EMAC mode and while bringing up the second interface in cpsw_ndo_set_rx_mode() all the multicast entries added by the first interface is flushed out and only second interface multicast addresses are added. Fixing this by flushing multicast addresses based on dual EMAC port vlans which will not affect the other emac port multicast addresses.
