Subject: [NET]: Change "not found" return value for rule lookup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=83886b6b636173b206f475929e58fac75c6f2446;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[NET]: Change "not found" return value for rule lookup

This changes the "not found" error return for the lookup
function to -ESRCH so that it can be distinguished from
the case where a rule or route resulting in -ENETUNREACH
has been found during the search.

It fixes a bug where if DECnet was compiled with routing
support, but no routes were added to the routing table,
it was failing to fall back to endnode routing.
