In the Config.in file of package foo, it often happens that there are other
symbols besides BR2_PACKAGE_FOO. Typically, these symbols only make sense
when foo itself is enabled. There are two ways to express this: with
depends on BR2_PACKAGE_FOO
in each extra symbol, or with
if BR2_PACKAGE_FOO
...
endif
around the entire set of extra symbols.
The if/endif approach avoids the repetition of 'depends on' statements on
multiple symbols, so this is clearly preferred. But even when there is only
one extra symbol, if/endif is a more logical choice:
- it is future-proof for when extra symbols are added
- it allows to have just one strategy instead of two (less confusion)
This patch modifies the Config.in files accordingly.

ØMQ (ZeroMQ, 0MQ, zmq) looks like an embeddable networking
|
|
library but acts like a concurrency framework. It gives you
|
|
sockets that carry whole messages across various transports
|
|
like in-process, inter- process, TCP, and multicast. You can
|
|
connect sockets N-to-N with patterns like fanout, pub-sub,
|
|
task distribution, and request-reply. It's fast enough to
|
|
be the fabric for clustered products. Its asynchronous I/O
|
|
model gives you scalable multicore applications, built as
|
|
asynchronous message-processing tasks. It has a score of
|
|
language APIs and runs on most operating systems.
|
|
|
|
ØMQ is from iMatix and is LGPL open source.

Add support for Pragmatic General Multicast protocol (RFC 3208)

implemented either over raw IP packets or UDP datagrams
