[PATCH] proxy: Skip VPNs that route everything for proxy.pac

[Michael Tremer <michael.tremer@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1197 bytes --]

The function tries to figure out which networks are connected locally,
but VPN tunnels that use 0.0.0.0 and GRE/VTI interfaces will be
considered local and the proxy is being disabled for everyone.
