For now, only add L2_TUNNEL_TO_L2 option. This will allow to perform
generic decap operation if the encapsulating protocol is L2 based, and the

This test creates a raw IPv4 socket, fragments a largish UDP
datagram and sends the fragments out of order.
Then repeats in a loop with different message and fragment lengths.
Then does the same with overlapping fragments (with overlapping
fragments the expectation is that the recv times out).
The current behavior of IP defragmentation is inconsistent:
- some overlapping/wrong length fragments are dropped without
affecting the queue;
- most overlapping fragments cause the whole frag queue to be dropped.
This patch brings consistency: if a bad fragment is detected,

The software SA record counters should not be cleared when clearing
the hardware tables. This causes the counters to be out of sync
after a driver reset.

There seems to be a problem in the x540's internal switch wherein if SR-IOV
mode is enabled and an offloaded IPsec packet is sent to a local VF,
the packet is silently dropped. This might never be a problem as it is
somewhat a corner case, but if someone happens to be using
This series contains updates to ixgbe and ixgbevf only.
Sebastian adds support for firmware NVM recovery mode, which logs a
message when errors are detected and un-registers the device. Also
fixed RSS type recognition with VF to VF communication.

To enable easier FW distribution NFP can now automatically
select between FW stored on the flash and loaded from the
kernel.
If FW loading policy is set to auto it will compare the
versions of FW from the host and from the flash and load
the newer one. If FW type doesn't match (e.g. one advanced
The sysfs field was introduced 4 years ago along with fixes to various
drivers that erroneously used `dev_id' for that purpose, but it was not
properly documented anywhere.

Some InfiniBand network devices have multiple ports on the same PCI
function. This initializes the `dev_port' sysfs field of those
network interfaces with their port number.
The use of `dev_id' was considered correct until Linux 3.15,
when another field, `dev_port', was defined for this
Some InfiniBand network devices have multiple ports on the same PCI
function. Prior to this the kernel erroneously used the `dev_id' sysfs
field of those network interfaces to convey the port number to userspace.
`dev_id' is currently reserved for distinguishing stacked ifaces

Pre-3.15 userspace had trouble distinguishing different ports
of a NIC on a single PCI bus/device/function. To solve this,
a sysfs field `dev_port' was introduced quite a while ago

drivers were fixed to use it, but not in case of

While VF2VF with RSS communication, RSS Type were wrongly recognized
and RSS hash was not calculated as it should be. Packets was
distributed on various queues by accident.
This commit fixes that behaviour and causes proper RSS Type recognition.
