From a03d9f94cc54199bf681729b16ba649d7206369e Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Wed, 9 Apr 2014 09:38:27 -0500 Subject: RDMA/cxgb4: Max fastreg depth depends on DSGL support The max depth of a fastreg mr depends on whether the device supports DSGL or not. So compute it dynamically based on the device support and the module use_dsgl option.
