qdisc statistics is exposed in netlink response but not parsed, here we
parse it and expose it via struct QdiscStatistics.

This commit add the support for alternative names.
* exposing the attributes in the link object.
* adding the add and delete functions
* allow LinkByName() to also find devices by altname like `ip link`

Functions added:
DevlinkGetDeviceParams - get all parameters for device
DevlinkGetDeviceParamByName - get specific parameter for device
DevlinkSetDeviceParam - set parameter for device

This commit added support to allow the operation of ip6tnl encapsulation.
It is equivalent to the iproute2 command, e.g., ip route add 192.168.99.0/24 encap ip6 dst 2001:db8:: dev ip6-tunnel
The limitation include that the options field defined in encap nl route attribute is not implenmented yet.
Testcase is included.
- Update nl package with new netlink attribute types and consts
- Define structs to model devlink device resources
- Add DevlinkGetDeviceResources method to return device resources
- Add basic test

The qdiscPayload() function was missing the TCA_FQ_PLIMIT attribute
for the Fq Qdisc. Therefore, it could not be changed via the library.
Fix this up, so that QdiscReplace() with different qdisc.PacketLimit
works now.

The xfrm framework is linux-only. Only implement the respective types
for GOOS=linux to avoid dependencies to x/sys/unix on non-linux or
non-unix platforms. Provide dummy XfrmPolicy and XfrmState types for the
globally defined XfrmPolicy* and XfrmState* functions.
With this, the skip message will display the position of the
helper invocation (i.e. the test that caused the skip) instead of the
position of the t.Skip call in minKernelRequired the helper.
TestRouteFilterAllTables and TestRouteExtraFields started failing a
while ago after GitHub actions images bumped the kernel version from
5.15.x to 6.2.x [1].
This is because newer kernels containing commit [2] started rejecting
Tos values with the ECN bits set to non-zero, this leads to the
following error being reported when adding routes:
invalid argument: Invalid dsfield (tos): ECN bits must be 0
Fix this by using a valid Tos value in TestRouteFilterAllTables and
TestRouteExtraFields.

This causes the NETLINK_EXT_ACK socket option to be set and extended
error messages to be reported in errors. This should help debug test
failures.
Also use errors.Is to check for errors because using extended error
reporting, the errors no longer match exactly.
When there are a large number of existing results for the link, neighbor, and
address subscribe functions with ListExisting are likely to fail with ENOBUFS.
This takes the AddrSubscribeOptions ReceiveBufferSize, already applied
to LinkSubscribeOptions, and applies it to NeighSubscribeOptions and
RouteSubscribeOptions. The ReceiveTimeout option was also added to each.
Added a SetReceiveBufferSize to the nl_linux socket API.
The existing addr_linux subscribe function was modified so instead of setting
the ReceiveBufferSize on the netlink pkghandle, it is set on the socket
associated with the subscription. The new implementations also only change the
receive buffer size on the socket.
Lastly, a new ReceiveBufferForceSize option was applied to all four of the
modified Subscribe functions.
Sometimes with `ListExisting` enabled and enough interfaces configured,
netlink will try to send more data than the buffer can hold and the
caller will get back ENOBUFS. Thus, it's useful to be able to configure
the netlink buffer size.
The IFLA_GENEVE_COLLECT_METADATA netlink attribute shouldn't have any a
payload. For Geneve devices also other attributes can be set next to
FlowBased, however the VNI needs to be 0.
This commit also adds a test for creating a Geneve device in FlowBased
mode.

IFLA_IPTUN_COLLECT_METADATA is a "flag" netlink attribute, and shouldn't
have any payload. This also needs to be considered when parsing netlink
messages for Iptun.
This fixes Iptun link, by crafting and parsing messages accordingly and
adds a test.

Commit 2b008399a4 ("link: add LinkSetGSOIPv4MaxSize and
LinkSetGROIPv4MaxSize") introduced the use of these constants, but they
were added only recently to the golang.org/x/sys/unix package. Update
its version in go.mod and use the pre-defined constants instead of
duplicating them.
