[PATCH] devlink: Fix incorrect skb socket family dumping

From: lirongqing

Date: Mon Apr 06 2026 - 22:28:09 EST


From: Li RongQing <lirongqing@xxxxxxxxx>

The devlink_fmsg_dump_skb function was incorrectly using the socket
type (sk->sk_type) instead of the socket family (sk->sk_family)
when filling the "family" field in the fast message dump.

This patch fixes this to properly display the socket family.

Fixes: 3dbfde7f6bc7b8 ("devlink: add devlink_fmsg_dump_skb() function")
