[SRU][kernel-snaps-u24.04/pi][PATCH 0/1] pi-kernel does not ship PPP drivers (LP: #2106751)

[ Impact ]

Hi there

The linux-raspi kernel package in Ubuntu is missing essential kernel modules
required for PPP (Point-to-Point Protocol) functionality using pppd. This
prevents common use cases such as connecting via serial modems, USB cellular
modems, or establishing PPPoE connections.

The following configurations needed to be added;
CONFIG_PPP
CONFIG_PPP_ASYNC
CONFIG_PPP_DEFLATE
CONFIG_PPP_BSDCOMP
CONFIG_PPP_MPPE
CONFIG_PPP_SYNC_TTY
CONFIG_PPPOE
CONFIG_PPPOL2TP
CONFIG_PPTP

Impacted kernel: 6.8
OS version: Ubuntu Core 24, Ubuntu 24.04

Thanks,
Bugra

[ Fix ]

Include ppp kernel modules in pi-kernel snap.

[ Test Case ]

Install kernel snap, verify new kernel modules are present and usable.

[ Where Problems Could Occur ]

This adds additional drivers to the snap. If they get loaded, the usual kernel problems can occur (stack traces, crashes, ...).
