      i40e: Clean up handling of msglevel flags and debug parameter · 5d4ca23e
      由 Alexander Duyck 提交于 
      So the i40e driver had a really convoluted configuration for how to handle
the debug flags contained in msg_level.  Part of the issue is that the
driver has its own 32 bit mask that it was using to track a separate set of
debug features.  From what I can tell it was trying to use the upper 4 bits
to determine if the value was meant to represent a bit-mask or the numeric
value provided by debug level.

What this patch does is clean this up by compressing those 4 bits into bit
31, as a result we just have to perform a check against the value being
negative to determine if we are looking at a debug level (positive), or a
debug mask (negative).  The debug level will populate the msg_level, and
the debug mask will populate the debug_mask in the hardware struct.

I added similar logic for ethtool.  If the value being provided has bit 31
set we assume the value being provided is a debug mask, otherwise we assume
it is a msg_enable mask.  For displaying we only provide the msg_enable,
and if debug_mask is in use we will print it to the dmesg log.

Lastly I removed the debugfs interface.  It is redundant with what we
already have in ethtool and really doesn't belong anyway.

      i40e: refactor Rx filter handling · c3c7ea27
      由 Mitch Williams 提交于 
      Properly track filter adds and deletes so the driver doesn't lose filters
during resets and up/down cycles. Add a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.

Implement a simple state machine so the driver can track the status of
each filter throughout its lifecycle. Properly manage the overflow promiscuous
state for the each VSI, and provide a way for the driver to detect when to exit
overflow promiscuous mode.

Remove all possible default MAC filters that the firmware may have set up so
that the driver can manage these correctly, particularly when VLANs come into
play. Remove the LAA flag for filters; instead just send whatever we get through
set_mac to the firmware as the LAA for wakeup purposes.

Finally, add the state of each filter to debugfs output so we can see what's
going on inside the driver's pointy little head.

      i40e: Fix for recursive RTNL lock during PROMISC change · 30e2561b
      由 Anjali Singhai 提交于 
      The sync_vsi_filters function can be called directly under RTNL
or through the timer subtask without one. This was causing a deadlock.

If sync_vsi_filters is called from a thread which held the lock,
and in another thread the PROMISC setting got changed we would
be executing the PROMISC change in the thread which already held
the lock alongside the other filter update. The PROMISC change
requires a reset if we are on a VEB, which requires it to be called
under RTNL.

Earlier the driver would call reset for PROMISC change without
checking if we were already under RTNL and would try to grab it
causing a deadlock. This patch changes the flow to see if we are
already under RTNL before trying to grab it.

      i40e: start up in VEPA mode by default · fc60861e
      由 Anjali Singhai Jain 提交于 
      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.

      i40e: Add support for getlink, setlink ndo ops · 51616018
      由 Neerav Parikh 提交于 
      Add support for bridge offload ndo_ops getlink and setlink to
enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE.
The support is only enabled in case of a PF VSI and not available for
any other VSI type.

By default the i40e driver inserts a bridge as part of the bring-up
when a FDIR type VSI and/or a FCoE VSI is created. This bridge is
created in VEB mode by default i.e. after creating the bridge using
"Add VEB" AQ command the loopback for the PF's default VSI is enabled.

The patch adds capability where all the VSIs created as downlink to
the bridge inherits the loopback property and enables loopback only
if the uplink bridge is operating in VEB mode.
Hence, there is no need to explicitly enable loopback as part of
allocating resources for SR-IOV VFs and call to do that has been
removed.

In case a user-request is made either via "bridge" utility or using
the bridge netlink interface that requires to change the hardware
bridge mode then that would require a PF reset and rebuild of the
switch hierarchy.

Also update the copyright year.
