From e7a7b84e33178db4a839c5e1773247be17597c1f Mon Sep 17 00:00:00 2001 From: Veerendranath Jakkam Date: Sat, 30 Jul 2022 10:56:43 +0530 Subject: wifi: cfg80211: Add link_id parameter to various key operations for MLO Add support for various key operations on MLD by adding new parameter link_id. Pass the link_id received from userspace to driver for add_key, get_key, del_key, set_default_key, set_default_mgmt_key and set_default_beacon_key to support configuring keys specific to each MLO link. Userspace must not specify link ID for MLO pairwise key since it is common for all the MLO links.
