[Buildroot] [PATCH] package/python-can: remove msgpack dependency

[Buildroot] [PATCH] package/python-can: remove msgpack dependency

[Marcus Hoffmann via buildroot]

Dependency was made optional in 4.6.0 release here:
https://github.com/hardbyte/python-can/commit/6058ab9dfe8b3ba5d23cbff670c0fe767147390a

python-can has a lot of optional dependencies, most of which are not
represented in buildroot. As msgpack is used for the virtual multicast
udp can interface[1], which does seem like a bit of a niche usecase,
just drop the mandatory dependency without introducing a user-visible
config option to enable it.
