From: Miquel Raynal Date: Wed, 27 Sep 2023 18:12:04 +0000 (+0200) Subject: ieee802154: Let PAN IDs be reset X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5260adf86b6732c75136fc1b159bb370062ddfa8;p=linux.git ieee802154: Let PAN IDs be reset Soon association and disassociation will be implemented, which will require to be able to either change the PAN ID from 0xFFFF to a real value when association succeeded, or to reset the PAN ID to 0xFFFF upon disassociation. Let's allow to do that manually for now.
