2015-12-02net: thunderx: Set CQ timer threshold properlySunil Goutham
Properly set CQ timer threshold and also set it to 2us. With previous incorrect settings it was set to 0.5us which is too less. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-30net: thunderx: Support for internal loopback modeSunil Goutham
Support for setting VF's corresponding BGX LMAC in internal loopback mode. This mode can be used for verifying basic HW functionality such as packet I/O, RX checksum validation, CQ/RBDR interrupts, stats e.t.c. Useful when DUT has no external network connectivity. 'loopback' mode can be enabled or disabled via ethtool. Note: This feature is not supported when no of VFs enabled are morethan no of physical interfaces i.e active BGX LMACs Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: Aleksey Makarov <aleksey.makarov@caviumnetworks.com> Signed-off-by: David S.

2015-08-30net: thunderx: Support for upto 96 queues for a VFSunil Goutham
This patch adds support for handling multiple qsets assigned to a single VF. There by increasing no of queues from earlier 8 to max no of CPUs in the system i.e 48 queues on a single node and 96 on dual node system. User doesn't have option to assign which Qsets/VFs to be merged. Upon request from VF, PF assigns next free Qsets as secondary qsets. To maintain current behavior no of queues is kept to 8 by default which can be increased via ethtool. If user wants to unbind NICVF driver from a secondary Qset then it should be done after tearing down primary VF's interface.

2015-08-30net: thunderx: Rework interrupt handlingSunil Goutham
Rework interrupt handler to avoid checking IRQ affinity of CQ interrupts. Now separate handlers are registered for each IRQ including RBDR. Register interrupt handlers for only those which are being used. Add nicvf_dump_intr_status() and use it in irq handlers.

2015-08-30net: thunderx: Add receive error stats reporting via ethtoolSunil Goutham
Added ethtool support to dump receive packet error statistics reported in CQE. Also made some small fixes Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: Aleksey Makarov <aleksey.makarov@caviumnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-07-29net: thunderx: Set watchdog timeout valueSunil Goutham
If a txq (SQ) remains in stopped state after this timeout its considered as stuck and interface is reinited. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: Aleksey Makarov <aleksey.makarov@caviumnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-07-29net: thunderx: Wakeup TXQ only if CQE_TX are processedSunil Goutham
Previously TXQ is wakedup whenever napi is executed and irrespective of if any CQE_TX are processed or not. Added 'txq_stop' and 'txq_wake' counters to aid in debugging if there are any future issues.

2015-06-24net: Cavium: Fix MAC address setting in shutdown statePavel Fedin
This bug pops up with NetworkManager on Fedora 21. NetworkManager tends to stop the interface (nicvf_stop() is called) before changing settings. In stopped state MAC cannot be sent to a PF. However, when the interface is restarted (nicvf_open() is called), we ping the PF using NIC_MBOX_MSG_READY message, and the PF replies back with old MAC address, overriding what we had after MAC setting from userspace. As a result, we cannot set MAC address using NetworkManager. This patch introduces special tracking of MAC change in stopped state so that the correct new MAC address is sent to a PF when interface is reopen.

2015-06-02net: thunderx: Cleanup duplicate NODE_ID macros, add nic_get_node_id()Robert Richter
There are duplicate NODE_ID macro definitions. Move all of them to nic.h for usage in nic and bgx driver and introduce nic_get_node_id() helper function.
