[PATCH net-next v5 00/10] Decouple receive and transmit enablement in team driver

[Marc Harvey <marcharvey@google.com>]

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 10).

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

  teardown before using sigkill.
- Make the teamd activebackup selftest in patch 5 delete leftover
  teamd files during teardown.
