From 158c776dba1f6b5eb2e3d5327cda719dc4820c1c Mon Sep 17 00:00:00 2001 From: Hariprasad S Date: Tue, 8 Sep 2015 09:56:58 +0530 Subject: [PATCH] iw_cxgb4: pass the ord/ird in connect reply events This allows client ULPs to get the negotiated ord/ird which is useful to avoid stalling the SQ due to exceeding the ORD.
