2018-01-12ixgbe: Do not manipulate macvlan Tx queues when performing macvlan offloadAlexander Duyck2-108/+25
We should not be stopping/starting the upper devices Tx queues when handling a macvlan offload. Instead we should be stopping and starting traffic on our own queues. In order to prevent us from doing this I am updating the code so that we no longer change the queue configuration on the upper device, nor do we update the queue_index on our own device. Instead we can just use the queue index for our local device and not update the netdev in the case of the transmit rings.

2018-01-12ixgbe/fm10k: Record macvlan stats instead of Rx queue for macvlan offloaded ↵Alexander Duyck2-10/+14
rings We shouldn't be recording the Rx queue on macvlan offloaded frames since the macvlan is normally brought up as a single queue device, and it will trigger warnings for RPS if we have recorded queue IDs larger than the "real_num_rx_queues" value recorded for the device. Instead we should be recording the macvlan statistics since we are bypassing the normal macvlan statistics that would have been generated by the receive path.

2018-01-12ixgbe: Don't assume dev->num_tc is equal to hardware TC configAlexander Duyck6-27/+29
The code throughout ixgbe was assuming that dev->num_tc was populated and configured with the driver, when in fact this can be configured via mqprio without any hardware coordination other than restricting us to the real number of Tx queues we advertise. Instead of handling things this way we need to keep a local copy of the number of TCs in use so that we don't accidentally pull in the TC configuration from mqprio when it is configured in software mode.

2018-01-12ixgbe: Default to 1 pool always being allocatedAlexander Duyck2-5/+3
We might as well configure the limit to default to 1 pool always for the interface. This accounts for the fact that the PF counts as 1 pool if SR-IOV is enabled, and in general we are always running in 1 pool mode when RSS or DCB is enabled as well, though we don't need to actually evaluate any of the VMDq features in those cases.

2018-01-12ixgbe: Assume provided MAC filter has been verified by macvlanAlexander Duyck1-4/+8
The macvlan driver itself will validate the MAC address that is configured for a given interface. There is no need for us to verify it again. Instead we should be checking to verify that we actually allocate the filter and have not run out of resources to configure a MAC rule in our filter table.

Jake changes how the driver determines whether or not the device is currently up to resolve the possible issue of freeing data structures and other memory before they have been fully allocated. Refactored the driver to simplify the locking behavior and to consistently use spinlocks instead of an overloaded bit lock to protect MAC and filter lists. Created a helper function which can convert the AdminQ link speed definition into a virtchnl definition. Colin Ian King cleans up a redundant variable initialization. Alex cleans up the driver to stop clearing the pending bit array for each vector manually, since it is prone to dropping an interrupt and based on the hardware specs, the pending bit array will be cleared automatically in MSI-X mode. Cleaned up flags for promiscuous mode to resolve an issue where enabling & disabling promiscuous mode on a VF would leave us in a high polling rate for the adminq task. Cleaned up code that was prone to race issues. Jingjing renames pipeline personalization profile (ppp) to dynamic device personalization (ddp) because it was being confused with the well known point to point protocol.
