You should use linkmode_copy() instead. =20 >=20 > No, we don't want to copy pl->supported to > pl->link_config.lp_advertising.

Ok, so the right thing should be this: linkmode_or(pl->link_config.lp_advertising, pl->link_config.lp_advertising, match) Regards, --=20 K=C3=B6ry Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
