Subject: [PATCH for-rc v2 2/8] RDMA/bnxt_re: Detect wrong sge_len passed for inline
Date: Wed, 9 Sep 2026 06:52:38 -0700 [thread overview]
Message-ID: <20260909135244.122747-2-selvin.xavier@broadcom.com> (raw)
In-Reply-To: <20260909135244.122747-1-selvin.xavier@broadcom.com>
Avoid handling wrong sge_len by adding extra check
to see if the passed length is more than the inline
size supported.
Fixes: 1ac5a4047975 ("RDMA/bnxt_re: Add bnxt_re RoCE driver")
