New Revision: 265413
URL: http://svnweb.freebsd.org/changeset/base/265413

Log:
  MFC: r264517
  Vlan did not set the value of if_hw_tsomax, so when vlan
  was stacked on top of a network interface that set if_hw_tsomax,
  tcp_output() would see the default value instead of the value
  set by the network interface. This patch modifies vlan so that
  it sets if_hw_tsomax to the value of the parent interface.
