NFS: Parse and store all multipath DS addresses
This parses and stores all addresses associated with each data server, laying the groundwork for supporting multipath to data servers. - Skips over addresses that cannot be parsed (ie IPv6 addrs if v6 is not enabled). Only fails if none of the addresses are recognizable - Currently only uses the first address that parsed cleanly - Tested against pynfs server (modified to support multipath) Signed-off-by: Weston Andros Adamson <dros@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
