Author: rmacklem Date: Tue Apr 15 21:48:35 2014 New Revision: 264517 URL: http://svnweb.freebsd.org/changeset/base/264517 Log: 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.
