* fm10k: send traffic on default VID to VLAN device if we have oneJacob Keller2015-09-151-0/+12
| | | | | | | | | | | | | | | | This patch ensures that VLAN traffic on the default VID will go to the corresponding VLAN device if it exists. To do this, mask the rx_ring VID if we have an active VLAN on that VID. For this to work correctly, we need to update fm10k_process_skb_fields to correctly mask off the VLAN_PRIO_MASK bits and compare them separately, otherwise we incorrectly compare the priority bits with the cleared flag. This also happens to fix a related bug where having priority bits set causes us to incorrectly classify traffic.

* fm10k: allow creation of VLAN interfaces even while downJacob Keller2015-09-151-0/+6
| | | | | | | | | | We re-sync upon going up, so there is little reason to worry about not syncing immediately with switch. This prevents an error that occurs if you add a VLAN interface while down.

* fm10k: update netdev perm_addr during reinit, instead of at upJacob Keller2015-09-151-15/+0
| | | | | | | | | | | Update the netdev permanent address during fm10k_reinit enables the user to immediately see the new MAC address on the VF even if the device isn't up. The previous code required that the device by opened before changes would appear.

* fm10k: only prevent removal of default VID rulesJacob Keller2015-09-151-2/+2
| | | | | | | | | | | | | This allows us to correctly add a VLAN even if it matches our default VID. However, we don't want to remove the VID rules once that VLAN is deleted. Correctly remove the stack layers information of the VLAN, but then return to forwarding that VID as untagged frames. If we deleted the VID rules here, we would begin dropping traffic due to VLAN membership violations.

* fm10k: remove extraneous NULL check on l2_accelJacob Keller2015-06-171-2/+1
| | | | | | | | | | l2_accel was checked for NULL at the top of fm10k_dfwd_del_station, and we return if it is not defined. Due to this, we already know it can't be null here so a separate check is meaningless. Discovered via cppcheck.

* fm10k: ignore invalid multicast address entriesJacob Keller2015-06-171-7/+1
| | | | | | | | | | | | | | | | | | This change fixes an issue with adding an invalid multicast address using the iproute2 tool (ip maddr add <MADDR> dev <dev>). The iproute2 tool and the kernel do not validate or filter the multicast addresses when adding them to the multicast list. Thus, when synchronizing this list with an invalid entry, the action will be aborted with an error since the fm10k driver currently validates the list. Consequently, multicast entries beyond the invalid one will not be processed and communicated with the switch via the mailbox. This change makes it so that invalid addresses will simply be skipped and allows synchronizing the full list to proceed.

* fm10k: update xcast mode before synchronizing multicast addressesJeff Kirsher2015-04-141-11/+11
| | | | | | | | | | | | | | When the PF receives a request to update a multicast address for the VF, it checks the enabled multicast mode first. Fix a bug where the VF tried to set a multicast address before requesting the required xcast mode. This ensures the multicast addresses are honored as long as the xcast mode was allowed.

* fm10k: Add support for PTPAlexander Duyck2014-09-231-0/+20
| | | | | | | | | | | | | | | | | | | | | | | This change adds support for the Linux PTP Hardware clock and timestamping functionality provided by the hardware. There are actually two cases that this timestamping is meant to support. The first case would be an ordinary clock scenario. In this configuration the host interface does not have access to BAR 4. However all of the host interfaces should be locked into the same boundary clock region and as such they are all on the same clock anyway. With this being the case they can synchronize among themselves and only need to adjust the offset since they are all on the same clock with the same frequency. The second case is a boundary clock scenario. This is a special case and would require both BAR 4 access, and a means of presenting a netdev per boundary region. The current plan is to use DSA at some point in the future to provide these interfaces, but the DSA portion is still under development.

* fm10k: Add support for MACVLAN accelerationAlexander Duyck2014-09-231-0/+154
| | | | | | | | | | | | This patch adds support for L2 MACVLAN by making use of the fact that the RRC provides a unique tag per filter called a Global Resource Tag, or GLORT. In the case of this offload what I have done is assigned a linear block of these so that each GLORT represents one of the MACVLAN netdevs. By doing this I can share the Rx queues and Tx queues for all of the MACVLAN netdevs while allowing them to be demuxed in the Rx cleanup path.
