2013-11-06net: Explicitly initialize u64_stats_sync structures for lockdepJohn Stultz1-1/+8
In order to enable lockdep on seqcount/seqlock structures, we must explicitly initialize any locks. The u64_stats_sync structure, uses a seqcount, and thus we need to introduce a u64_stats_init() function and use it to initialize the structure. This unfortunately adds a lot of fairly trivial initialization code to a number of drivers. But the benefit of ensuring correctness makes this worth while. Because these changes are required for lockdep to be enabled, and the changes are quite trivial, I've not yet split this patch out into 30-some separate patches, as I figured it would be better to get the various maintainers thoughts on how to best merge this change along with the seqcount lockdep enablement. Feedback would be appreciated!

2012-04-21team: allow to enable/disable portsJiri Pirko1-1/+1
This patch changes content of hashlist (used to get port struct by computed index (0...en_port_count-1)). Now the hash list contains only enabled ports so userspace will be able to say what ports can be used for tx/rx. This becomes handy when userspace will need to disable ports which does not belong to active aggregator. By default, newly added port is enabled.
