From 457fe7b8a6822907cbe65897dc81b83d9df5bcbf Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Mon, 26 Nov 2007 11:28:46 -0600 Subject: [PATCH] RDMA/cxgb3: Support version 5.0 firmware The 5.0 firmware now supports translating sgls in recv work requests, so remove the host driver logic currently doing the translation. Note: this change requires 5.0 firmware.
