From: Steve Wise Date: Tue, 15 Jul 2008 06:48:48 +0000 (-0700) Subject: RDMA/cxgb3: Add support for protocol statistics X-Git-Tag: v2.6.27-rc1~1090^2~28 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=14cc180f7b032f8484c1a3d0533b1129ffe307fd;p=linux-2.6 RDMA/cxgb3: Add support for protocol statistics - Add a new rdma ctl command called RDMA_GET_MIB to the cxgb3 low level driver to obtain the protocol mib from the rnic hardware. - Add new iw_cxgb3 provider method to get the MIB from the low level driver.
