From 30b03b1528b60623986ee0b50ec0e5dab9094be8 Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Fri, 19 Aug 2016 07:29:08 -0700 Subject: [PATCH] iw_cxgb4: use the MPA initiator's IRD if < our ORD The i40iw initiator sends an MPA-request with ird=16 and ord=16. The cxgb4 responder sends an MPA-reply with ord = 32 causing i40iw to terminate due to insufficient resources. The logic to reduce the ORD to <= peer's IRD was wrong.
