New Revision: 255198
URL: http://svnweb.freebsd.org/changeset/base/255198
Log:
For TOE connections, the window scale factor in CPL_PASS_ACCEPT_REQ is
set to 15 to indicate that the peer did not send a window scale option
with its SYN. Do not send a window scale option in the SYN|ACK reply
in that case.
