ioctl. Also, all agents registered through a file descriptor will
be unregistered when the descriptor is closed.
2014 -- a new registration ioctl is now provided which allows additional
fields to be provided during registration.
Users of this registration call are implicitly setting the use of
pkey_index (see below).
Receiving MADs
MADs are received using read(). The receive side now supports

The old ib_umad interface did not allow setting the P_Key index for
MADs that are sent and did not provide a way for obtaining the P_Key
index of received MADs. A new layout for struct ib_user_mad_hdr
with a pkey_index member has been defined; however, to preserve
binary compatibility with older applications, this new layout will
not be used unless the IB_USER_MAD_ENABLE_PKEY ioctl is called
before a file descriptor is used for anything else.
with a pkey_index member has been defined; however, to preserve binary
compatibility with older applications, this new layout will not be used
unless one of IB_USER_MAD_ENABLE_PKEY or IB_USER_MAD_REGISTER_AGENT2 ioctl's
are called before a file descriptor is used for anything else.
In September 2008, the IB_USER_MAD_ABI_VERSION will be incremented
to 6, the new layout of struct ib_user_mad_hdr will be used by
