Author: zec

New Revision: 222247
URL: http://svn.freebsd.org/changeset/base/222247

Log:
  Allow for vlan(4) interfaces with MTU of 1500 bytes to be configured
  on top of epair(4) virtual interfaces, since there's no physical
  hardware associated with epair interfaces which would imply any
  constraints on MTU sizes.
