Subject: [PATCH rdma-next 1/1] RDMA/mana_ib: take CQ type from the device type
Date: Fri, 9 Jan 2026 04:37:30 -0800 [thread overview]
Message-ID: <1767962250-2118-1-git-send-email-kotaranov@linux.microsoft.com> (raw)
From: Konstantin Taranov <kotaranov@microsoft.com>
Get CQ type from the used gdma device. The MANA_IB_CREATE_RNIC_CQ
flag is ignored. It was used in older kernel versions where
the mana_ib was shared between ethernet and rnic.
Fixes: d4293f96ce0b ("RDMA/mana_ib: unify mana_ib functions to support any gdma device")
