Subject: [PATCH 3.11 040/208] team: fix master carrier set when user linkup is enabled

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

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

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

commit f5e0d34382e18f396d7673a84df8e3342bea7eb6 upstream.

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.
