[PATCH 03/14] ibacm: use sysfs (in acm_if_is_ib) rather than ioctl(... SIOCGIFHWADDR ...) to read interface type

From: Ira Weiny ira.we...@intel.com Getting an interface type from sysfs is easier than using an ioctl when an interface name is readily available (as is the case with netlink.) In preparation for netlink support create a function which uses sysfs and use it instead of ioctls. Signed-off-by:

[PATCH 05/14] ibacm: Move calling of helper functions out of get_devaddr

From: Ira Weiny ira.we...@intel.com Again this is in prep for sharing this code with ibacm and ib_acme get_devaddr uses globals which are specific to ib_acme. Move toward this function being ib_acme specific while the code in get_addr_ip becomes generic. Signed-off-by: Ira Weiny

[PATCH 12/14] ibacm: fix handling of aliased IPoIB devices

From: Ira Weiny ira.we...@intel.com ibX:Y devices don't have sysfs files directly. They use the base interface of ibX. The ioctl calls however include the full aliased name. Netlink does not have this problem as the interface name is reported as it appears in sysfs. Signed-off-by: Ira Weiny
