From: Jon Mason Date: Tue, 15 Jul 2008 06:48:49 +0000 (-0700) Subject: RDMA/cxgb3: Propagate HW page size capabilities X-Git-Tag: v2.6.27-rc1~1090^2~20 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=52c8084b740c42af27d5bfa62cec7079d12fbc2b;p=linux-2.6 RDMA/cxgb3: Propagate HW page size capabilities cxgb3 does not currently report the page size capabilities, and incorrectly reports them internally. This version changes the bit-shifting to a static value (per Steve's request).
