-    while (options && *options) {
+    for (; options && *options; options++) {

options cannot be NULL (ever). Can we change that too?

Otherwise, lgtm

Okay.

I realized there was a missing part: if the connection has

 bond.options "mode=balance-rr,tlb_dynamic_lb=2"

(which is a weird configuration, but it is accepted), it will never match on restart because the generated connection doesn't have the 'tlb_dynamic_lb' option.

Added a commit to remove unsupported options from connection upon normalization.
