[Tarantool-patches] [PATCH 1/2] swim: add SO_BROADCAST option

[Vladislav Shpilevoy]

I force updated the patch on the branch.

Could you please check if it works on your machine? For
example, this test:

	uuid = require('uuid')
	swim = require('swim')

	s = swim.new({uuid = uuid(), uri = '127.0.0.1:3313'})

	s:broadcast(3313)

On Mac it used to print EADDRNOTAVAIL message. Probably
would fail with something on Linux too, but I don't know.
Might just work fine as well.
