2016-10-17arm: vf610: zii devel b: Add support for switch interruptsAndrew Lunn1-0/+51

2016-10-17net: phy: Use phy name when requesting the interruptAndrew Lunn1-2/+1

2016-10-17net: phy: Threaded interrupts allow some simplificationAndrew Lunn3-22/+30
The PHY interrupts are now handled in a threaded interrupt handler, which can sleep. The work queue is no longer needed, phy_change() can be called directly. phy_mac_interrupt() still needs to be safe to call in interrupt context, so keep the work queue, and use a helper to call phy_change().

2016-10-17net: phy: Use threaded IRQ, to allow IRQ from sleeping devicesAndrew Lunn1-4/+4
The interrupt lines from PHYs maybe connected to I2C bus expanders, or from switches on MDIO busses. Such interrupts are sourced from devices which sleep, so use threaded interrupts. Threaded interrupts require that the interrupt requester also uses the threaded API. Change the phylib to use the threaded API, which is backwards compatible with none-threaded IRQs.

The Marvell PHY driver can then be used in interrupt mode, rather than polling, speeding up PHY handling and reducing load on the MDIO bus.

This l3mdev_ops structure is only stored in the l3mdev_ops field of a net_device structure. This field is declared const, so the l3mdev_ops structure can be declared as const also.

2016-10-15ila: Cache a route to translated addressTom Herbert1-6/+74
Add a dst_cache to ila_lwt structure. This holds a cached route for the translated address. In ila_output we now perform a route lookup after translation and if possible (destination in original route is full 128 bits) we set the dst_cache. Subsequent calls to ila_output can then use the cache to avoid the route lookup. This eliminates the need to set the gateway on ILA routes as previously was being done. Now we can do something like: ./ip route add 3333::2000:0:0:2/128 encap ila 2222:0:0:2 \ csum-mode neutral-map dev eth0 ## No via needed!

2016-10-14qed: Handle malicious VFs eventsYuval Mintz3-20/+96
Malicious VFs might be caught in several different methods: - Misusing their bar permission and being blocked by hardware. - Misusing their fastpath logic and being blocked by firmware. - Misusing their interaction with their PF via hw-channel, and being blocked by PF driver. On the first two items, firmware would indicate to driver that the VF is to be considered malicious, but would sometime still allow the VF to communicate with the PF [depending on the exact nature of the malicious activity done by the VF]. The current existing logic on the PF side lacks handling of such events, and might allow the PF to perform some incorrect configuration on behalf of a VF that was previously indicated as malicious. The new scheme is simple - Once the PF determines a VF is malicious it would: a. Ignore any further requests on behalf of the VF-driver. b. Prevent any configurations initiated by the hyperuser for the malicious VF, as firmware isn't willing to serve such. The malicious indication would be cleared upon the VF flr, after which it would become usable once again. Signed-off-by: Yuval Mintz <Yuval.Mintz@caviumnetworks.com> Signed-off-by: David S.

2016-10-14qed: Allow chance for fast ramrod completionsYuval Mintz1-26/+59
Whenever a ramrod is being sent for some device configuration, the driver is going to sleep at least 5ms between each iteration of polling on the completion of the ramrod. However, in almost every configuration scenario the firmware would be able to comply and complete the ramrod in a manner of several usecs. This is especially important in cases where there might be a lot of sequential configurations applying to the hardware [e.g., RoCE], in which case the existing scheme might cause some visible user delays. This patch changes the completion scheme - instead of immediately starting to sleep for a 'long' period, allow the device to quickly poll on the first iteration after a couple of usecs.

2016-10-14qed*: Allow unicast filteringYuval Mintz3-3/+14
Apparently qede fails to set IFF_UNICAST_FLT, and as a result is not actually performing unicast MAC filtering. While we're at it - relax a hard-coded limitation that limits each interface into using at most 15 unicast MAC addresses before turning promiscuous. Instead utilize the HW resources to their limit.

2016-10-14qede: Prevent GSO on long Geneve headersManish Chopra1-0/+35
Due to hardware limitation, when transmitting a geneve-encapsulated packet with more than 32 bytes worth of geneve options the hardware would not be able to crack the packet and consider it a regular UDP packet. This implements the ndo_features_check() in qede in order to prevent GSO on said transmitted packets.

2016-10-14qed: Pass MAC hints to VFsYuval Mintz3-4/+8
Some hypervisors can support MAC hints to their VFs. Even though we don't have such a hypervisor API in linux, we add sufficient logic for the VF to be able to receive such hints and set the mac accordingly - as long as the VF has not been set with a MAC already.

2016-10-14net/sched: act_mirred: Implement ingress actionsShmulik Ladkani1-6/+45
Up until now, 'action mirred' supported only egress actions (either TCA_EGRESS_REDIR or TCA_EGRESS_MIRROR). This patch implements the corresponding ingress actions TCA_INGRESS_REDIR and TCA_INGRESS_MIRROR. This allows attaching filters whose target is to hand matching skbs into the rx processing of a specified device.

2016-10-14net/sched: tc_mirred: Rename public predicates 'is_tcf_mirred_redirect' and 'is_tcf_mirred_mirror'Shmulik Ladkani6-7/+9
These accessors are used in various drivers that support tc offloading, to detect properties of a given 'tc_action'. 'is_tcf_mirred_redirect' tests that the action is TCA_EGRESS_REDIR. 'is_tcf_mirred_mirror' tests that the action is TCA_EGRESS_MIRROR. As a prep towards supporting INGRESS redir/mirror, rename these predicates to reflect their true meaning: s/is_tcf_mirred_redirect/is_tcf_mirred_egress_redirect/ s/is_tcf_mirred_mirror/is_tcf_mirred_egress_mirror/ Signed-off-by: Shmulik Ladkani <shmulik.ladkani@gmail.com> Cc: Hariprasad S <hariprasad@chelsio.com> Cc: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Cc: Saeed Mahameed <saeedm@mellanox.com> Cc: Jiri Pirko <jiri@mellanox.com> Cc: Ido Schimmel <idosch@mellanox.com> Cc: Jakub Kicinski <jakub.kicinski@netronome.com> Acked-by: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: David S.
