[arrggg -- made the same mistake -- this version actually has the missing line I intended to add in the v2 -- sorry for the noise] iproute2 patch to generalize VXLAN forwarding tables This is the iproute2 support allowing an administrator to specify alternate ports, vnis and outgoing interfaces for VXLAN device forwarding tables. Changes since v2: fixed missing port assignment for ports-by-name Signed-Off-By: David L Stevens <dlstevens@us.ibm.com> -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
