Subject: [PATCH for-next] RDMA/core: Unify RoCE check and re-factor code
Date: Tue,  6 Apr 2021 12:37:03 +0200
Message-ID: <1617705423-15570-1-git-send-email-haakon.bugge@oracle.com> (raw)

In cm_req_handler(), unify the check for RoCE and re-factor to avoid
one test.

Suggested-by: Jason Gunthorpe <jgg@nvidia.com>
Fixes: 8f9748602491 ("IB/cm: Reduce dependency on gid attribute ndev check")
Fixes: 194f64a3cad3 ("RDMA/core: Fix corrupted SL on passive side")
