[ Upstream commit fb9eb899a6dc663e4a2deed9af2ac28f507d0ffb ]
When link transitions from LINK_FAIL to LINK_UP, the commit phase is not called. This leads to an erroneous state causing slave-link state to get stuck in "going down" state while its speed and duplex are perfectly fine. This issue is a side-effect of splitting link-set into propose and commit phases introduced by de77ecd4ef02 ("bonding: improve link-status update in mii-monitoring")
This patch fixes these issues by calling commit phase whenever link state change is proposed.
