bonding: document two undocumented options.
Commit 655f8919d549ad1872e24d826b6ce42530516d2e bonding: add min links parameter to 802.3ad and commit ebd8e4977a87cb81d93c62a9bff0102a9713722f bonding: add all_slaves_active parameter introduced new options to bonding, but didn't provide the documentation for those options. V2: add the default value for both options. V3: document the exact behavior of min_links default value. Signed-off-by: Nicolas de Peslo√ľan <> Signed-off-by: David S. Miller <>

This option was added in bonding version 3.4.0.

+ Normally, bonding will drop duplicate frames (received on inactive

+ Specifies the minimum number of links that must be active before
