Bug#1034506: Request to enable CONFIG_HSR as module

[Yoann Congal <yoann.congal@smile.fr>]

Source: linux
Severity: wishlist
Tags: newcomer patch
X-Debbugs-Cc: yoann.congal@smile.fr

Hi maintainers,

HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy
Protocol) are two network protocols used in environment where network
node failure should not trigger a frame loss. Both provide seamless
failover against this kind of failure.

Both of these are enabled in kernel by CONFIG_HSR which is currently
disabled.

HSR and PRP are defined in IEC 62439-3:2016 and used in many industrial
standards (in our case, IEC 61850 about connected systems in electrical
substations)

This module is handled by iproute2 since 5.10 (available in bullseye).

I've already created a merge-request for this request : 
https://salsa.debian.org/kernel-team/linux/-/merge_requests/682

Thank you for considering this request.

Best regards,
