* net: thunderx: Enable BGX LMAC's RX/TX only after VF is upSunil Goutham2015-12-023-3/+38
| | | | | | | | | | | | | Enable or disable BGX LMAC's RX/TX based on corresponding VF's status. If otherwise, when multiple LMAC's physical link is up then packets from all LMAC's whose corresponding VF is not yet initialized will get forwarded to VF0. This is due to VNIC's default configuration where CPI, RSSI e.t.c point to VF0/QSET0/RQ0. This patch will prevent multiple copies of packets on VF0.

* net: thunderx: Switchon carrier only upon interface link upSunil Goutham2015-12-023-4/+18
| | | | | | | | | | | Call netif_carrier_on() only if interface's link is up. Switching this on upon IFF_UP by default, is causing issues with ethernet channel bonding in LACP mode. Initial NETDEV_CHANGE notification was being skipped. Also fixed some issues with link/speed/duplex reporting via ethtool. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S.

* net: thunderx: Rewrite silicon revision tests.David Daney2015-10-251-4/+6
| | | | | | | | | | | | | | The test for pass-1 silicon was incorrect, it should be for all revisions less than 8. Also the revision is already present in the pci_dev, so there is no need to read and keep a private copy. Remove rev_id and code to read it from struct nicpf. Create new static inline function pass1_silicon() to be used to testing the silicon version. Use pass1_silicon() for revision checks, this will be more widely used in follow on patches.

* net: thunderx: Support for upto 96 queues for a VFSunil Goutham2015-08-305-84/+505
| | | | | | | | | | | | | | | | | | 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.

* net: thunderx: Support for HW VLAN strippingSunil Goutham2015-08-304-7/+55
| | | | | | | | | | | | | | | | | | | This patch configures HW to strip 802.1Q header if found in a receiving packet. The stripped VLAN ID and TCI information is passed on to software via CQE_RX. Also sets netdev's 'vlan_features' so that other HW offload features can be used for tagged packets. This offload feature can be enabled or disabled via ethtool. Network stack normally ignores RPS for 802.1Q packets and hence low throughput. With this offload enabled throughput for tagged packets will be almost same as normal packets. Note: This patch doesn't enable HW VLAN insertion for transmit packets.

| | | | | | | | | | | | | | | | | | | | | With earlier configured value sufficient number of CQEs are not being reserved for transmitted packets. Hence under heavy incoming traffic load, receive notifications will take away most of the CQ thus transmit notifications will be lost resulting in tx skbs not being freed. Finally SQ will be full and it will be stopped, watchdog timer will kick in. After this fix receive notifications will not take morethan half of CQ reserving the rest for transmit notifications. Also changed CQ & SQ sizes from 16k to 4k. This is also due to the receive notifications taking first half of CQ under heavy load and time taken by NAPI to clear transmit notifications will increase with higher queue sizes. Again results in SQ being stopped. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: Aleksey Makarov <aleksey.makarov@caviumnetworks.com> Signed-off-by: David S.

* net: Cavium: Fix MAC address setting in shutdown statePavel Fedin2015-06-242-2/+13
| | | | | | | | | | | | | | | | 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.
