[dpdk-dev] [PATCH 8/8] bond: do not activate slave twice

[Stephen Hemminger]

From: Eric Kinzie <ekinzie at brocade.com>

The current code for detecting link during slave addition can cause a
slave interface to be activated twice -- once during slave_configure()
and again at the end of __eth_bond_slave_add_lock_free().  This will
either cause the active slave count to be incorrect or will cause the
802.3ad activation function to panic.  Ensure that the interface is not
activated more than once.
