The simplest thing to implement is moving network devices between namespaces. However with the same attribute IFLA_NET_NS_PID we can easily implement creating devices in the destination network namespace as well. However that is a little bit trickier so this patch sticks to what is simple and easy. A pid is used to identify a process that happens to be a member of the network namespace we want to move the network device to. Signed-off-by: Eric W.

IFF_* flags.

The only change is:
|
|
IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
|
|
more not changeable by user. They describe link media
|
|
characteristics and set by device driver.
|
|
|
|
Comments:
|
|
- Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
|
|
- If neither of these three flags are set;
|
|
the interface is NBMA.
|
|
|
|
- IFF_MULTICAST does not mean anything special:
|
|
multicasts can be used on all not-NBMA links.
|
|
IFF_MULTICAST means that this media uses special encapsulation
|
|
for multicast frames. Apparently, all IFF_POINTOPOINT and
|
|
IFF_BROADCAST devices are able to use multicasts too.

For usual devices it is equal ifi_index.

If it is a "virtual interface" (f.e. tunnel), ifi_link

can point to real physical interface (f.e. for bandwidth calculations),

|
or maybe 0, what means, that real media is unknown (usual
|
|
for IPIP tunnels, when route to endpoint is allowed to change)
