First let me apologize because it appears as if the
patch we submitted is the source of the problem.
The patch was submitted to allow ACCM to be
negotiated. The suspect line of code was moved to
allow the ACCM values to be setup before the LCP was
initialized.
Instead of moving the line of code back to its
original spot (which would break the patch), can we
instead remove the wo initialization within
cyg_ppp_options_install into ipcp_init.c?
Maintainers -- do you want me to submit a patch on
this?
