Hi Steven,
I have a little question just as the title said?
In Ofono how to connect PPP to Linux socket, when we receive packet
from network, how the packet go through the kernel to application？
modem -->PPP-->? --> linux kernel(network part)--> socket -->
application?
it is more like this:
modem -> TTY -> PPP -> TUN/TAP -> Kernel Net-Stack -> socket ->
application.
With the TTY being in kernel, the PPP being in userspace, and TUN/TAP
etc. begin in the kernel again.
A future enhancement is to use the kernel PPP layer, but we haven't
gotten there yet.
I am interested to know how could we use kernel PPP layer instead of gatppp.
Shall we add this item into our TODO?
Maybe you can reference to RILD in Android, it used kernel PPP.
