Notes from Mike Siers <email@example.com>
I know that several users have tried out this version of
pppd under RTEMS. It has been successfully used as both
a client and server. Below are the only issues that I
1) Large packet ping causes RTEMS box to lock up
If you ping the RTEMS box over the ppp link with a packet
size greater than 1500, the RTEMS box locks up. I think
the problem is in the pppd ethernet driver.
2) Upgrade the libnetworking/modem files
This upgrade did not modify the ppp ethernet driver files
in the libnetworking/modem directory. Would like to
upgrade these files. Hopefully, it will fix the large
packet ping problem.
3) The files cbcp.c and cbcp.h provide a callback feature
that I have not tried to compile or use. The files in
this directory are identical to the 2.3.11 versions.
JOEL: Are the modifications to the original pppd such that the
real maintainers will accept them?
No. The pppd 2.3.11 branch is an old branch. The current
version is 2.4.x and it contains alot of extra items that
just did not make sense to have in an embedded environment.
I could make the RTEMS changes compatible with the standard
2.3.11 release by using compilation flags. I have not
contacted the maintainers to see if they are interested.
