Subject: Force gatetway to zero instead of adding a host route when the interface
X-Git-Tag: v5.2.3~14
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ebf31ea0173ae6769ef3addf60ff71c4096a48e9;p=thirdparty%2Fdhcpcd.git

Force gatetway to zero instead of adding a host route when the interface
does not support ARP. This improves performance slighty.
Addresses #188.
