If anyone has any objections, please let me know. ------------------ From: Youssef Samir [ Upstream commit ff194cffd586cbd4cc49eccb002c65f2a902a277 ] The current node limit of 64 breaks the functionality for a number of AI200 deployments that have up to 384 nodes. Raise the limit to 512. Also, the backport of commit 27d5e84e810b ("net: qrtr: ns: Limit the total number of nodes") to 5.10, 5.15 and 6.1 dropped the node_count-- hunk in ctrl_cmd_bye(). Add it back.
