[Impact]
When using DW5823E WWAN modem (iosm kernel module) with IPSec (xfrm kernel module), the system will eventually hang after using the network.

[Fix]
The upstream fix is still under review here:
https://lore.kernel.org/netdev/20240912071702.221128-1-en-wei.wu@canonical.com/

Out of the urgency, we'd apply this patch to be an Ubuntu sauce patch into Noble 6.8.

[Test Plan]
1. Install the latest Ubuntu oem / public image on the system with DW5823e WWAN card
2. insert the SIM card into the GSM modem and establish a connection to the GSM network
3. setting up an IPSec tunnel (through the XFRM kernel module).
4. launching a browser, e.g. Firefox, and running any HTML page on the remote side (i.e. tunnel communication), even a 'ping' through tunnel will cause the issue

[Where problems could occur]
May cause regression.
