Problem is that when followed by one of these layers, the EtherType field

While specifying EtherType/TPID is hopefully rarely necessary, the stacking
order in case of QinQ and the lack of documentation remain an issue.

When facing encapsulated (e.g. tunneled) packets, there is an ambiguity as

This is addressed by adding encapsulation level information to the RSS flow
action. Its default value is 0 and stands for the usual unspecified
behavior. Other values provide a specific encapsulation level.

ethdev: alter behavior of flow API actions

This patch makes the following changes to flow rule actions:

- List order now matters, they are redefined as performed first to last
  instead of "all simultaneously".

- Repeated actions are now supported (e.g. specifying QUEUE multiple times
  now duplicates traffic among them). Previously only the last action of
  any given kind was taken into account.

- No more distinction between terminating/non-terminating/meta actions.
  Flow rules themselves are now defined as always terminating unless a
  PASSTHRU action is specified.

These changes alter the behavior of flow rules in corner cases in order to
prepare the flow API for actions that modify traffic contents or properties
(e.g. encapsulation, compression) and for which order matter when combined.

Previously one would have to do so through multiple flow rules by combining
PASSTRHU with priority levels, however this proved overly complex to
implement at the PMD level, hence this simpler approach.

This breaks ABI compatibility for the following public functions:

- rte_flow_create()
- rte_flow_validate()

PMDs with rte_flow support are modified accordingly:

- bnxt: no change, implementation already forbids multiple actions and does
  not support PASSTHRU.

- e1000: no change, same as bnxt.

- enic: modified to forbid redundant actions, no support for default drop.

- failsafe: no change needed.

- i40e: no change, implementation already forbids multiple actions.

- ixgbe: same as i40e.

- mlx4: modified to forbid multiple fate-deciding actions and drop when
  unspecified.

- mlx5: same as mlx4, with other redundant actions also forbidden.

- sfc: same as mlx4.

- tap: implementation already complies with the new behavior except for
  the default pass-through modified as a default drop.

net/vdev_netvsc: prefer netvsc devices in scan

There is an option to run a non-netvsc device as a netvsc device only
when the "force" parameter is set to 1 in the EAL command line.
Consequently, more than one device may be found to be matching the
"mac" parameter specifying the device.

Prefer netvsc devices to be scanned before any non-netvsc device, even
when the "force" parameter is set.

6 years agonet/vdev_netvsc: add check for specifying by 1 way

net/vdev_netvsc: add check for specifying by 1 way

There are now 2 ways to specify a netvsc device by the EAL command
line - either by the interface name or by the MAC address.

The user should not specify a netvsc device using more than 1 way,
Thus, if a device is specified in more than 1 way, the driver stops
to probe it.

Validate it in the driver initialization.

net/vdev_netvsc: remove specified devices IP check

If the netvsc driver starts in blacklist mode, it does not
automatically probe IP associated netvsc devices. Therefore, the only
way to probe them is to specify them by the EAL command line, using the
"force" parameter to skip the IP check in the driver.

>From now on, the user does not need to add the "force" parameter if he
specifies an IP associated netvsc device by the EAL command line, and the
responsibility of the IP check is now in the user's hands.

However, in the absence of any specification, the driver still skips IP
associated netvsc devices.

It will be used for non-standard tunnels.

The support from the device is for inner and outer checksums on
IPV4/TCP/UDP and TSO for *any packet with the following format*:

<some headers> / [optional IPv4/IPv6] / [optional TCP/UDP] / <some

For example the following packets can use this feature:

1. eth / ipv4 / udp / VXLAN / ip / tcp
2. eth / ipv4 / GRE / MPLS / ipv4 / udp

Please note that specific tunnel headers that contain payload length,
