Subject: iproute2: support NTF_ROUTER flag in VXLAN fdb entries
X-Git-Tag: v3.10.0~36
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5b8a1d4a03df76b077649e58522fbb4054769273;p=thirdparty%2Fiproute2.git

iproute2: support NTF_ROUTER flag in VXLAN fdb entries

This patch allows setting the "NTF_ROUTER" flag in VXLAN forwarding table
entries to enable L3 switching for router destinations while still allowing
L2 redirection appliances for non-router MAC destinations.
