2016-11-29mwifiex: pcie: implement timeout loop for FW programming doorbellBrian Norris
Marvell Wifi PCIe modules don't always behave nicely for PCIe power management when their firmware hasn't been loaded, particularly after suspending the PCIe link one or more times. When this happens, we might end up spinning forever in this status-polling tight loop. Let's make this less tight by adding a timeout and by sleeping a bit in between reads, as we do with the other similar loops. This prevents us from hogging a CPU even in such pathological cases, and allows the FW initialization to just fail gracefully instead. I chose the same polling parameters as the earlier loop in this function, and empirically, I found that this loop never makes it more than about 12 cycles in a sane FW init sequence. I had no official information on the actual intended latency for this portion of the download.

2016-11-28qlogicpti: Fix compiler warningsTushar Dave
qlogicpti uses '__u32' for dma handle while invoking kernel DMA APIs, instead of using dma_addr_t. This hasn't caused any 'incompatible pointer type' warning on SPARC because until now dma_addr_t is of type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit DMA and therefore dma_addr_t became of type u64. This makes 'incompatible pointer type' warnings inevitable. e.g. drivers/scsi/qlogicpti.c: In function ‘qpti_map_queues’: drivers/scsi/qlogicpti.c:813: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type ./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’ drivers/scsi/qlogicpti.c:822: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type ./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’ For the record, qlogicpti never executes on sun4v. Therefore even though 64bit DMA is enabled on SPARC, qlogicpti continues to use legacy iommu that guarantees DMA address is always in 32bit range. This patch resolves aforementioned compiler warnings. Signed-off-by: Tushar Dave <tushar.n.dave@oracle.com> Reviewed-by: thomas tai <thomas.tai@oracle.com> Signed-off-by: David S.

2016-11-28net/mlx5e: Read ETS settings directly from firmwareHuy Nguyen
Issue description: Current implementation saves the ETS settings from user in a temporal soft copy and returns this settings when user queries the ETS settings. With the new DCBX firmware, the ETS settings can be changed by firmware when the DCBX is in firmware controlled mode. Therefore, user will obtain wrong values from the temporal soft copy. Solution: 1. Read the ETS settings directly from firmware. 2. For tc_tsa: a. Initialize tc_tsa to vendor IEEE_8021QAZ_TSA_VENDOR at netdev creation. b. When reading ETS setting from FW, if the traffic class bandwidth is less than 100, set tc_tsa to IEEE_8021QAZ_TSA_ETS. This implementation solves the scenarios when the DCBX is in FW control and willing bit is on which means the ETS setting is dictated by remote switch. Also check ETS capability where needed.

2016-11-28virtio-net: enable multiqueue by defaultJason Wang
We use single queue even if multiqueue is enabled and let admin to enable it through ethtool later. This is used to avoid possible regression (small packet TCP stream transmission). But looks like an overkill since: - single queue user can disable multiqueue when launching qemu - brings extra troubles for the management since it needs extra admin tool in guest to enable multiqueue - multiqueue performs much better than single queue in most of the cases So this patch enables multiqueue by default: if #queues is less than or equal to #vcpu, enable as much as queue pairs; if #queues is greater than #vcpu, enable #vcpu queue pairs.

2016-11-28net: phy: realtek: fix enabling of the TX-delay for RTL8211FMartin Blumenstingl
The old logic always enabled the TX-delay when the phy-mode was set to PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the PHY driver to enable the RX and/or TX delays: - PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the PHY (if required, the MAC should add the delays in this case) - PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY - PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY - PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY (currently not supported by RTL8211F) With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID and PHY_INTERFACE_MODE_RGMII_TXID. Additionally we now explicity disable the TX-delay, which seems to be enabled automatically after a hard-reset of the PHY (by triggering it's reset pin) to get a consistent state (as defined by the phy-mode). This fixes a compatibility problem with some SoCs where the TX-delay was also added by the MAC. With the TX-delay being applied twice the TX clock was off and TX traffic was broken or very slow (<10Mbit/s) on 1000Mbit/s links.

Since long already bpf_func is not only about struct sk_buff * as input anymore. Make it generic as void *, so that callers don't need to cast for it each time they call BPF_PROG_RUN().
