Subject: RDMA/cxgb3: Set active_mtu in ib_port_attr
X-Git-Tag: v2.6.28-rc1~727^2^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c752c78275fbf3fcb1d6d0af9b03ac999fe1963d;p=platform%2Fkernel%2Flinux-3.10.git

RDMA/cxgb3: Set active_mtu in ib_port_attr

When running ibv_devinfo, the active_mtu returned is garbage.  This is
due to the field not being populated in the query_port function in the
driver.  The patch below populates the active_mtu field with a MTU of
2k.  It also zeros the struct, so that any new additions to it will
return 0.
