Doc Text:
A vulnerability in the Linux kernel affects the High-availability Seamless Redundancy (HSR) protocol. The issue was identified when a warning (WARN_ONCE()) was triggered due to failed resource allocation for skb in the hsr_init_skb() function. The WARN_ONCE() was initially used to log this failure, but it was not deemed helpful in resolving it. Instead, the kernel maintainers switched to using netdev_warn_once() to better handle the failure and avoid excessive warning reports.
