The 'trivial' lpm implementation in this test allows equivalent nodes
to be added (that is, nodes consisting of the same prefix and prefix
length). For lookup operations, this is fine because insertion happens
at the head of the (singly linked) list and the first, best match is
returned. In order to support deletion, the tlpm data structue must
first enforce uniqueness. This change modifies the insertion algorithm
to search for equivalent nodes and remove them. Note: the
BPF_MAP_TYPE_LPM_TRIE already has a uniqueness invariant that is
implemented as node replacement.

HiperSockets allow configuring so called VNIC Characteristics (VNICC)
that influence how the underlying hardware handles packets. For VNICCs,
additional commands for getting and setting timeouts are available.
Currently, the learning VNICC uses these commands.
* Learning VNICC: If learning is enabled on a qeth device, the device
learns the source MAC addresses of outgoing packets and incoming
packets to those learned MAC addresses are received.
For learning, the timeout specifies the idle period in seconds, after
which the underlying hardware removes a learned MAC address again.
This patch adds support for the IPA commands that are required to get
and set the current timeout values for the learning VNIC characteristic.
Also, it introduces the sysfs interface that allows users to configure
the timeout.

HiperSocket devices allow enabling and disabling so called VNIC
Characteristics (VNICC) that influence how the underlying hardware
handles packets. These VNICCs are:
* Flooding VNICC: Flooding allows specifying if packets to unknown
destination MAC addresses are received by the qeth device.
* Multicast flooding VNICC: Multicast flooding allows specifying if
packets to multicast MAC addresses are received by the qeth device.
* Learning VNICC: If learning is enabled on a qeth device, the device
learns the source MAC addresses of outgoing packets and incoming
packets to those learned MAC addresses are received.
* Takeover setvmac VNICC: If takeover setvmac is configured on a qeth
device, the MAC address of this device can be configured on a
different qeth device with the setvmac IPA command.
* Takeover by learning VNICC: If takeover learning is enabled on a qeth
device, the MAC address of this device can be learned (learning VNICC)
on a different qeth device.
* BridgePort invisible VNICC: If BridgePort invisible is enabled on a
qeth device, (1) packets from this device are not sent to a BridgePort
enabled qeth device and (2) packets coming from a BridgePort enabled
qeth device are not received by this device.
* Receive broadcast VNICC: Receive broadcast allows configuring if a
qeth device receives packets with the broadcast destination MAC
address.
This patch adds support for the IPA commands that are required to enable
and disable these VNIC characteristics on qeth devices. As a
prerequisite, it also adds the query commands IPA command.
The query commands IPA command allows requesting the supported commands
for each characteristic from the underlying hardware.
Additionally, this patch provides users with a sysfs user interface to
enable/disable the VNICCs mentioned above.

VNIC Characteristics (VNICC) are features of HiperSockets that define
how packets are handled by the underlying network hardware. For example,
if the VNICC flooding is configured on a qeth device, ethernet frames to
unknown destination MAC addresses are received.
Currently, there is support for seven VNICCs: flooding, multicast
flooding, receive broadcast, learning, takeover learning, takeover
setvmac, bridge invisible. Also, six IPA commands exist for configuring
VNICCs on a qeth device: query characteristics, query commands, enable
characteristic, disable characteristic, set timeout, get timeout.
This patch adds the basic code infrastructure for VNICC support to qeth.
It allows querying VNICC support from the underlying hardware. To this
end, it adds:
* basic message formats for IPA commands
* basic data structures
* basic error handling
* query characteristics IPA command support
The query characteristics IPA command allows requesting the currently
supported and currently enabled VNIC characteristics from the underlying
hardware.
Support for the other IPA commands and for the configuration of VNICCs
is added in follow-up patches together with the respective user
interface functions.
