From: James Smart <redacted> [ Upstream commit 9302154c07bff4e7f7f43c506a1ac84540303d06 ] The wqe_dbde field indicates whether a Data BDE is present in Words 0:2 and should therefore should be clear in the abts request wqe. By setting the bit we can be misleading fw into error cases. Clear the wqe_dbde field.
