Merge branch 'bonding-802-3ad-fix-no-transmission-of-lacpdus'

Jonathan Toppins says:

====================
bonding: 802.3ad: fix no transmission of LACPDUs

Configuring a bond in a specific order can leave the bond in a state
where it never transmits LACPDUs.

The first patch adds some kselftest infrastructure and the reproducer
that demonstrates the problem. The second patch fixes the issue. The
new third patch makes ad_ticks_per_sec a static const and removes the
passing of this variable via the stack.
