From: Patrisious Haddad Date: Tue, 3 Dec 2024 13:45:37 +0000 (+0200) Subject: RDMA/mlx5: Enforce same type port association for multiport RoCE X-Git-Tag: v6.1.124~71 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cbc35242a97a472ba8e3a87cac2ad861a4f9b164;p=thirdparty%2Fkernel%2Fstable.git RDMA/mlx5: Enforce same type port association for multiport RoCE [ Upstream commit e05feab22fd7dabcd6d272c4e2401ec1acdfdb9b ] Different core device types such as PFs and VFs shouldn't be affiliated together since they have different capabilities, fix that by enforcing type check before doing the affiliation.
