Subject: [RFC PATCH v9 05/26] RDMA/rxe: Remove rxe_drop_all_macst_groups
Date: Thu, 27 Jan 2022 15:37:34 -0600 [thread overview]
Message-ID: <20220127213755.31697-6-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20220127213755.31697-1-rpearsonhpe@gmail.com>
With o10-2.2.3 enforced rxe_drop_all_mcast_groups is completely
unnecessary. Remove it and references to it.
