[Devel] [PATCH 31/47] skb: make drop reason booleanable

[Nikolay Borisov]

From: Jakub Kicinski <kuba at kernel.org>

We have a number of cases where function returns drop/no drop
decision as a boolean. Now that we want to report the reason
code as well we have to pass extra output arguments.

We can make the reason code evaluate correctly as bool.

I believe we're good to reorder the reasons as they are
reported to user space as strings.
