Allow independent control over receive and transmit enablement states
for aggregated ports in the team driver.

The motivation is that IEE 802.3ad LACP "independent control" can't
be implemented for the team driver currently. This was added to the
bonding driver in commit 240fd405528b ("bonding: Add independent
control state machine").

This series also has a few patches that add tests to show that the old
coupled enablement still works and that the new decoupled enablement
works as intended (4, 5, and 7).

There are three patches with small fixes as well, with the goal of
making the final decouplement patch clearer (1, 2, and 3).

Sounds like Jiri asked for changes, when you respin could you run
shellcheck and clean up the warnings? We ignore SC2317 SC2329 FWIW
selftests confuse the checker.

I will send v4 soon after splitting up the main functional patch, as
Jiri requested. It appears all of the shellcheck errors are from
SC2329. I see a bunch of other warnings in patch 5 (from
tools/testing/selftests/net/lib.sh), but they are unrelated to the
changes from that patch.
