Hi John,

pkey (pronounced PEE KEY) stands for "partition keys" where partitions are
in a way IB's vlans, so the functionality provided by IPoIB child devices
is similar to what done by Ethernet 8021q vlan devices. Dave suggests
that we use rtnl_link_ops to create these childs instead of the proprietary
sysfs which was introduced when IPoIB was merged and is described here
Documentation/infiniband/ipoib.txt

Or.
