IB/core: Add gid attributes to sysfs This patch set adds attributes of net device and gid type to each GID in the GID table. Users that use verbs directly need to specify the GID index. Since the same GID could have different types or associated net devices, users should have the ability to query the associated GID attributes. Adding these attributes to sysfs.
