Subject: [PATCH] bond: let 'reapply()' reapply all supported options
Reapply now handles all the options supported by kernel and NM, meaning
that some options are simply not allowed to be set while keeping the
bond up, one of those options is the mode for instance.
https://bugzilla.redhat.com/show_bug.cgi?id=1847814
(cherry picked from commit 746dc119a6bceb6a08b4dc9f3798d0b59a4b8575)
(cherry picked from commit 88a399637a5279f43fd8fc7c511547fa1d179295)
