2016-08-19vmxnet3: fix tx data ring copy for variable sizeShrikrishna Khare2-3/+5
'Commit 3c8b3efc061a ("vmxnet3: allow variable length transmit data ring buffer")' changed the size of the buffers in the tx data ring from a fixed size of 128 bytes to a variable size. However, while copying data to the data ring, vmxnet3_copy_hdr continues to carry the old code that assumes fixed buffer size of 128. This patch fixes it by adding correct offset based on the actual data ring buffer size.

2016-08-18qede: Fix Tx timeout due to xmit_moreYuval Mintz1-1/+4
Driver uses netif_tx_queue_stopped() to make sure the xmit_more indication will be honored, but that only checks for DRV_XOFF. At the same time, it's possible that during transmission the DQL will close the transmission queue with STACK_XOFF indication. In re-configuration flows, when the threshold is relatively low, it's possible that the device has no pending tranmissions, and during tranmission the driver would miss doorbelling the HW. Since there are no pending transmission, there will never be a Tx completion [and thus the DQL would not remove the STACK_XOFF indication], eventually causing the Tx queue to timeout. While we're at it - also doorbell in case driver has to close the transmission queue on its own [although this one is less important - if the ring is full, we're bound to receive completion eventually, which means the doorbell would only be postponed and not indefinetly blocked].

2016-08-17net_sched: convert tcf_exts from list to pointer arrayWANG Cong3-5/+15
As pointed out by Jamal, an action could be shared by multiple filters, so we can't use list to chain them any more after we get rid of the original tc_action. Instead, we could just save pointers to these actions in tcf_exts, since they are refcount'ed, so convert the list to an array of pointers. The "ugly" part is the action API still accepts list as a parameter, I just introduce a helper function to convert the array of pointers to a list, instead of relying on the C99 feature to iterate the array.

Kshitiz Gupta provides a fix for igb to resolve the PHY delay compensation math in several functions. Jarod Wilson provides a fix for e1000e which had to broken up into 2 patches, first is prepares the driver for expanding the list of NICs that have occasional ~10 hour clock jumps when being used for PTP. Second patch actually fixes i218 silicon which has been experiencing the clock jumps while using PTP. Alex provides 2 patches for ixgbe now that he is back at Intel. First fixes setting VLNCTRL.VFE bit, which was left unchanged in earlier patches which resulted in disabling VLAN filtering for all the VFs. Second corrects the support for disabling the VLAN tag filtering via the feature bit. Lastly, David fixes i40e which was causing a kernel panic when non-contiguous traffic classes or traffic classes not starting with TC0, were configured on a link partner switch. To fix this, changed the logic when determining the total number of TCs enabled. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-08-17mlxsw: spectrum: Allow packets to be trapped from any PGIdo Schimmel1-1/+1
When packets enter the device they are classified to a priority group (PG) buffer based on their PCP value. After their egress port and traffic class are determined they are moved to the switch's shared buffer and await transmission, if: (Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres && Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres) || (Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min || Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min) Packets scheduled to transmission through CPU port (trapped to CPU) use traffic class 7, which has a zero maximum and minimum quotas. However, when such packets arrive from PG 0 they are admitted to the shared buffer as PG 0 has a non-zero minimum quota. Allow all packets to be trapped to the CPU - regardless of the PG they were classified to - by assigning a 10KB minimum quota for CPU port and TC7.

Commit bbf2a4757b30 ("mlxsw: spectrum: Initialize ports at the end of init sequence") moved ports initialization to the end of the init sequence, which means ports are the first to be removed during fini. Since the FDB delayed work is still active when ports are removed it's possible for it to process FDB notifications of inactive ports, resulting in a warning message. Fix that by marking ports as inactive only after unregistering them. The NETDEV_UNREGISTER event will invoke bridge's driver port removal sequence that will cause the FDB (and FDB notifications) to be flushed.

2016-08-16i40e: check for and deal with non-contiguous TCsDave Ertman1-10/+25
The i40e driver was causing a kernel panic when non-contiguous Traffic Classes, or Traffic Classes not starting with TC0, were configured on a link partner switch. i40e does not support non-contiguous TCs. To fix this, the patch changes the logic when determining the total number of TCs enabled. Before, this would use the highest TC number enabled and assume that all TCs below it were also enabled. Now, we create a bitmask of enabled TCs and scan it to determine not only the number of TCs, but also if the set of enabled TCs starts at zero and is contiguous. If not, then DCB is disabled by only returning one TC.

Back when I submitted the GSO code I messed up and dropped the support for disabling the VLAN tag filtering via the feature bit. This patch re-enables the use of the NETIF_F_HW_VLAN_CTAG_FILTER to enable/disable the VLAN filtering independent of toggling promiscuous mode.

2016-08-16ixgbe: Force VLNCTRL.VFE to be set in all VMDq pathsAlexander Duyck1-6/+12
When I was adding the code for enabling VLAN promiscuous mode with SR-IOV enabled I had inadvertently left the VLNCTRL.VFE bit unchanged as I has assumed there was code in another path that was setting it when we enabled SR-IOV. This wasn't the case and as a result we were just disabling VLAN filtering for all the VFs apparently. Also the previous patches were always clearing CFIEN which was always set to 0 by the hardware anyway so I am dropping the redundant bit clearing.

2016-08-16e1000e: fix PTP on e1000_pch_lpt variantsJarod Wilson1-1/+2
I've got reports that the Intel I-218V NIC in Intel NUC5i5RYH systems used as a PTP slave experiences random ~10 hour clock jumps, which are resolved if the same workaround for the 82574 and 82583 is employed, so set the appropriate flag2 in e1000_pch_lpt_info too.

2016-08-16e1000e: factor out systim sanitizationJarod Wilson3-29/+44
This is prepatory work for an expanding list of adapter families that have occasional ~10 hour clock jumps when being used for PTP. Factor out the sanitization function and convert to using a feature (bug) flag, per suggestion from Jesse Brandeburg. Littering functional code with device-specific checks is much messier than simply checking a flag, and having device-specific init set flags as needed. There are probably a number of other cases in the e1000e code that could/should be converted similarly.

2016-08-16igb: fix adjusting PTP timestamps for Tx/Rx latencyKshitiz Gupta1-3/+23
Fix PHY delay compensation math in igb_ptp_tx_hwtstamp() and igb_ptp_rx_rgtstamp. Add PHY delay compensation in igb_ptp_rx_pktstamp(). In the IGB driver, there are two functions that retrieve timestamps received by the PHY - igb_ptp_rx_rgtstamp() and igb_ptp_rx_pktstamp(). The previous commit only changed igb_ptp_rx_rgtstamp(), and the change was incorrect. There are two instances in which PHY delay compensations should be made: - Before the packet transmission over the PHY, the latency between when the packet is timestamped and transmission of the packets, should be an add operation, but it is currently a subtract. - After the packets are received from the PHY, the latency between the receiving and timestamping of the packets should be a subtract operation, but it is currently an add.

device pointers passed to DMA API Runtime warning occurs if DMA-API debug feature is enabled that would be raised by pointers passed to DMA API as arguments to inconsistent struct device objects, so that the patch makes them usage aligned between DMA operations such as dma_map_*() and dma_unmap_*() to eliminate the warning.

enabled properly Commit 08ef55c6f257acf3bdc6940813f80e8f0f5d90ec ("net-next: mediatek: fix gigabit and flow control advertisement") had supported proper flow control settings for GMAC1. But for GMAC0, 1.GMAC0 shares the common logic with GMAC1 inside mtk_phy_link_adjust() to adapt various settings for the target phy. 2.GMAC0 uses fixed-phy to connect to a builtin gigabit switch with fixed link speed as commit 0c72c50f6f93b0c3daa9ea35d89ab3a933c7b5a0 ("net-next: mediatek: add fixed-phy support") describes. 3.However, fixed-phy doesn't enable SUPPORTED_Pause & SUPPORTED_Asym_Pause supported flag on default that would cause mtk_phy_link_adjust() not to enable flow control setting on GMAC0 properly and cause packet dropped when high traffic. Due to these reasons, the patch adds SUPPORTED_Pause & SUPPORTED_Asym_Pause supported flags on fixed-phy used by the driver to have proper handling on the both GMAC with the shared common logic.

2016-08-15hv_netvsc: fix bonding devices check in netvsc_netdev_event()Vitaly Kuznetsov1-2/+7
Bonding driver sets IFF_BONDING on both master (the bonding device) and slave (the real NIC) devices and in netvsc_netdev_event() we want to skip master devices only. Currently, there is an uncertainty when a slave interface is removed: if bonding module comes first in netdev_chain it clears IFF_BONDING flag on the netdev and netvsc_netdev_event() correctly handles NETDEV_UNREGISTER event, but in case netvsc comes first on the chain it sees the device with IFF_BONDING still attached and skips it. As we still hold vf_netdev pointer to the device we crash on the next inject.
