New Revision: 242098
URL: http://svn.freebsd.org/changeset/base/242098
Log:
MFC 241496:
Some 3G modems return the wrong signature in echo packets and make it
impossible to use LQR/ECHO. They return want_magic instead.
With this change it is now possible to use
enable lqr
set lqrperiod 5
enable echo
set echoperiod 5
in your ppp.conf file.
