Subject: [PATCH 3.10 37/58] team: fix master carrier set when user linkup is enabled

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Pirko <jiri@...nulli.us>

[ Upstream commit f5e0d34382e18f396d7673a84df8e3342bea7eb6 ]

When user linkup is enabled and user sets linkup of individual port,
we need to recompute linkup (carrier) of master interface so the change
is reflected. Fix this by calling __team_carrier_check() which does the
needed work.

Please apply to all stable kernels as well. Thanks.
