Normally one should explain the changes from v1 to v2.

You should have CCed those who made comments to your previous version, and that's
Ben here.
"bond_update_sleep_duplex() must not be called in atomic context."
You didn't address his comment.

The codingstyle is awful...
if (slave->speed != SPEED_UNKNOWN &&
bond->params.mode == BOND_MODE_8023AD) {
