From e70cc3e07a9f509499cc3f5add269a7e0a5e331e Mon Sep 17 00:00:00 2001 From: Jack Morgenstein Date: Sun, 26 Nov 2006 09:10:19 +0200 Subject: [PATCH] IB/mthca: Fix initial SRQ logsize for mem-free HCAs When initializing an mthca SRQ, the log_srq_size field should be the log of the number of SRQ WQEs, not the log of the number of bytes in the SRQ. This affects only mthca drivers for memfree HCAs which set the initial srq wqe counter (in the SW2HW transition) to a non-zero value.
