40GbE Intel Wired LAN Driver Updates 2018-04-30
This series contains updates to i40e and i40evf only.
Jia-Ju Bai replaces an instance of GFP_ATOMIC to GFP_KERNEL, since
i40evf is not in atomic context when i40evf_add_vlan() is called.
Jake cleans up function header comments to ensure that the function
parameter comments actually match the function parameters. Fixed a
possible overflow error in the PTP clock code. Fixed warnings regarding
restricted __be32 type usage.
Mariusz fixes the reading of the LLDP configuration, which moves from
using relative values to calculating the absolute address.
Jakub adds a check for 10G LR mode for i40e.
Paweł fixes an issue, where changing the MTU would turn on TSO, GSO and
GRO.
Alex fixes a couple of issues with the UDP tunnel filter configuration.
First being that the tunnels did not have mutual exclusion in place to
prevent a race condition between a user request to add/remove a port and
an update. The second issue was we were deleting filters that were not
associated with the actual filter we wanted to delete.
Harshitha ensures that the queue map sent by the VF is taken into
account when enabling/disabling queues in the VF VSI.

When handling mirroring to a gretap or ip6gretap netdevice in mlxsw, the
underlay address (i.e. the remote address of the tunnel) may be routed
to a bridge.
In that case, look up the resolved neighbor Ethernet address in that
bridge's FDB. Then configure the offload to direct the mirrored traffic
to that port, possibly with tagging.

Changes to switchdev artifact can make a SPAN entry offloadable or
unoffloadable. To that end:
- Listen to SWITCHDEV_FDB_*_TO_BRIDGE notifications in addition to
the *_TO_DEVICE ones, to catch whatever activity is sent to the
bridge (likely by mlxsw itself).
On each FDB notification, respin SPAN to reconcile it with the FDB
changes.
- Also respin on switchdev port attribute changes (which currently
covers changes to STP state of ports) and port object additions and

When operating at 1GbE, the base incval for the PTP clock is so large
that multiplying it by numbers close to the max_adj can overflow the
u64.
Rather than attempting to limit the max_adj to a value small enough to
avoid overflow, instead calculate the incvalue adjustment based on the
40GbE incvalue, and then multiply that by the scaling factor for the
link speed.
This sacrifices a small amount of precision in the adjustment but we
avoid erratic behavior of the clock due to the overflow caused if ppb is
very near the maximum adjustment.

This fixes at least 2 issues I have found with the UDP tunnel filter
configuration.
The first issue is the fact that the tunnels didn't have any sort of mutual
exclusion in place to prevent an update from racing with a user request to
add/remove a port. As such you could request to add and remove a port
before the port update code had a chance to respond which would result in a
very confusing result. To address it I have added 2 changes. First I added
the RTNL mutex wrapper around our updating of the pending, port, and
filter_index bits. Second I added logic so that we cannot use a port that
has a pending deletion since we need to free the space in hardware before
we can allow software to reuse it.
The second issue addressed is the fact that we were not recording the
actual filter index provided to us by the admin queue. As a result we were
deleting filters that were not associated with the actual filter we wanted
to delete. To fix that I added a filter_index member to the UDP port
tracking structure.

i40evf_add_vlan() is never called in atomic context.
i40evf_add_vlan() is only called by i40evf_vlan_rx_add_vid(),
which is only set as ".ndo_vlan_rx_add_vid" in struct net_device_ops.
".ndo_vlan_rx_add_vid" is not called in atomic context.
Despite never getting called from atomic context,
i40evf_add_vlan() calls kzalloc() with GFP_ATOMIC,
which does not sleep for allocation.
GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,
which can sleep and improve the possibility of sucessful allocation.
This is found by a static analysis tool named DCNS written by myself.
