Author: tuexen Date: Tue May 24 11:47:14 2016 New Revision: 300603 URL: https://svnweb.freebsd.org/changeset/base/300603 Log: Allow an MTU of 65535 bytes to be set via TUN[SG]IFINFO. This requires changing the type on the mtu field in struct tuninfo from short to unsigned short. This is used, for example, by packetdrill to test with MTUs up to the maximum value.
