* i40e: clean up error status messagesShannon Nelson2015-07-231-161/+231
| | | | | | | | | | | | Clean up a little confusion in reporting error status in phy and fcoe setup error reports by separating the return status from the AQ error. Add two decoder functions to make this easier.

* i40e: Remove incorrect #ifdef'sCarolyn Wyborny2015-07-141-10/+2
| | | | | | | | | | | | | | | This patch removes some #ifdef's that should not be there. They were stopping code that is needed from being compiled in. With these #ifdef's removed, changes are needed in the driver to fix some compile errors: adding missing parameters to the definition of ndo_bridge_setlink and a ndo_dflt_brige_getlink call.

* i40e/i40evf: Add stats to track FD ATR and SB dynamic enable stateAnjali Singhai Jain2015-07-141-0/+12
| | | | | | | | | | | | | Since the driver can dynamically enable/disable FD ATR and SB features, these stats help keep track of the current state and along with fd_flush count provide a means to debug what could be going on with the flow director filters. This will take away the need for being verbose in our debug logs with respect to FD.

* switchdev; add VLAN support for port's bridge_getlinkScott Feldman2015-06-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One more missing piece of the puzzle. Add vlan dump support to switchdev port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how to show the vlans installed on the bridge and the device , but (until now) no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK msg. Before this patch, "bridge vlan show": $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlans 57 sw1p1 << device side vlans (missing) sw1p2 57 sw1p2 sw1p3 sw1p4 br0 None (When the port is bridged, the output repeats the vlan list for the vlans on the bridge side of the port and the vlans on the device side of the port. The listing above show no vlans for the device side even though they are installed). After this patch: $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlan 57 sw1p1 30-34 << device side vlans 57 3840 PVID sw1p2 57 sw1p2 57 3840 PVID sw1p3 3842 PVID sw1p4 3843 PVID br0 None I re-used ndo_dflt_bridge_getlink to add vlan fill call-back func. switchdev support adds an obj dump for VLAN objects, using the same call-back scheme as FDB dump. Support included for both compressed and un-compressed vlan dumps. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * i40e: start up in VEPA mode by defaultAnjali Singhai Jain2015-06-041-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch fixes a bug in the default configuration which prevented a software bridge loaded on the PF interface from working correctly because broadcast packets are incorrectly looped back. Fix the general case, by loading the driver in VEPA mode Until a VF or VMDq VSI is added. This way loopback on the Main VSI is turned off until needed and can resolve the issue of unnecessary reflection for users that do not have VF or VMDq VSIs setup. The driver must now coordinate the loopback setting for the Flow Director (FDIR) VSI to make sure it is in sync with the current VEB or VEPA mode setting. The user can still switch bridge modes from the bridge commands and choose to be in VEPA mode with VF VSIs. Because of hardware requirements, the call to switch to VEB mode when no VF/VMDqs are present will be rejected. NOTE: This patch uses BIT_ULL as that is preferred going forward, a followup patch in the lower priority queue to net-next will fix up the remaining 1 << usages.

| | | | | | | | | | | | | | | | This does not affect the Virtual channel API as such but it changes the meaning of what is communicated to the VSI resource struct as vsi_id. Earlier vsi_idx was being passed in, which was the index in the PF's VSI array. Now we pass vsi_id as communicated by the FW to the driver. This will help with future expansion of VF and FW communication. With this in place now the VF and Virtual channel driver change to move over to VSI id use is complete and is validated.

If the filter add error happens to be for SB we just auto disable SB. If filter error happens to be for ATR, auto disable ATR and mark the state to FD_FLUSH_REQUESTED. Which gets cleared when flush completes. If we are entering flush too quickly (< 30 seconds) and we have quite a few SB rules, its time to disable ATR for good. Since SB + ATR rules is most likely making the FD table unstable. ATR can be re-enabled by turning ntuple off (ethtool -K ntuple off) and will remain off after turning ntuple on till it gets unstable again.

* i40e: rework vector reservationShannon Nelson2015-03-071-19/+56
| | | | | | | | | | | | | | | | | The initial problem solved here is that the vector allocation was trying too hard to save vectors for VMDq, to the point of not giving the PF enough when in a tight situation such as an NPAR partition. This change makes sure that the PF will get all the queues and vectors it wants to fill out its destiny. Essentially, nothing is specially reserved for VMDq, it simply gets whatever is left after the PF, FCoE, and FD sideband get what they want. Additionally, the calculations for the reservations were harder to follow than necessary, so I've made it more straight forward.

* i40e: move IRQ tracking setup into MSIX setupShannon Nelson2015-03-051-31/+29
| | | | | | | | | | | Move the IRQ tracking setup and teardown into the same routines that do the IRQ setup and teardown. This keeps like activities together and allows us to track exactly the number of vectors reserved from the OS, which may be fewer than are available from the HW.

* i40e: Ioremap changesAnjali Singhai2015-03-051-2/+6
| | | | | | | | | | | | | | For future device support we do not want to map the whole CSR space since some of it is mapped by other drivers with different mapping methods. Note: As a side effect, the flash region (if exposed through the memory map) gets unmapped too since it follows the future use region.

* i40e: fix XPS mask when resettingJesse Brandeburg2015-03-051-11/+11
| | | | | | | | | | | | During resets (possibly caused by a Tx hang) the driver would accidentally clear the XPS mask for all queues back to 0. This caused higher CPU utilization and had some other performance impacts for transmit tests.

* i40e: Fix NPAR Tx Scheduler initGreg Rose2015-03-051-0/+4
| | | | | | | | | | | Recent changes to the driver initialization have caused the BW configurations to not take effect. We use a BW configuration read and write back to "kick" the Tx scheduler into action.

| * i40e: stop flow director on shutdownMitch A Williams2015-02-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases, the hardware would continue to try to access the FDIR ring after entering D3Hot state, which would cause either PCIe errors or NMIs, depending upon system configuration. Explicitly stop FDIR in our shutdown routine to eliminate this possibility.

| | | | | | | | | | | | | | | | | | | | | | | | | | Combine the ICR0 shutdown with the standard interrupt shutdown, and add the interrupt clearing to the PCI shutdown path. This prevents the driver from allowing stray interrupts or causing system logs from un-handled interrupts.
