This patch enables ibacm to process pathrecord queries through netlink.
Since ibacm can cache pathrecords, this implementation provides an easy
pathrecord cache for kernel components and therefore offers great
performance advantage on large fabric systems

A SA cache is undeniably critical for fabric scalability and performance.
In user space, the ibacm application provides a good example of pathrecord
cache for address and route resolution. With the recent implementation of

Currently, ibacm uses the first pkey on the local port to query SA. More
appropriately, it should use either 0x or 0x7fff for SA query.
However, if the local port is not configured with either pkey, ibacm will
continue to use the first pkey.
