- What I did
Ported a fix from libteam master to our master.
Fixes#4070Fixes#3649
- How I did it
Applied patch jpirko/libteam@c723737 from upstream.
- How to verify it
Build image for your DUT and warm-reboot your DUT 10 times. Check that all PortChannels are up and no error messages in teamd.log
In teamd v1.28, the port can only be enabled if sync bit is set
in recveived LACPDU from partner by the following commit
"teamd: lacp: update port state according to partner's sync bit"
(54f137c105)
However, lacp fallback feature needs to enable port even if partner
LACPDU is not received within a given period and fallback cfg is enabled.
To fix the lacp fallback breakage, we have to bypass the sync bit
check in lacp fallback mode.

The race condition could happen like this:
When an interface is enslaved into the port channel immediately after
it is created, the order of creating the ifinfo and linking the ifinfo to
the port is not guaranteed.
Please check the patch commit message to get full details.
