The function usnic_ib_qp_grp_get_chunk only returns an ERR_PTR value or a

from "InfiBand Architecture Specifications Volume 1":

  A QP is said to have a stale connection when only one side has
  connection information. A stale connection may result if the remote CM
  had dropped the connection and sent a DREQ but the DREQ was never
  received by the local CM. Alternatively the remote CM may have lost
  all record of past connections because its node crashed and rebooted,
  while the local CM did not become aware of the remote node's reboot
  and therefore did not clean up stale connections.

and:

   A local CM may receive a REQ/REP for a stale connection. It shall
   abort the connection issuing REJ to the REQ/REP. It shall then issue
   DREQ with "DREQ:remote QPN” set to the remote QPN from the REQ/REP.

This patch solves a problem with reuse of QPN. Current codebase, that
is IPoIB, relies on a REAP-mechanism to do cleanup of the structures
in CM. A problem with this is the timeconstants governing this
mechanism; they are up to 768 seconds and the interface may look
inresponsive in that period.  Issuing a DREQ (and receiving a DREP)
does the necessary cleanup and the interface comes up.

Currently when calling mlx5_add_flow_rule we accept
only one flow destination, this commit allows to pass
multiple destinations.

This change forces us to change the return structure to a more
flexible one. We introduce a flow handle (struct mlx5_flow_handle),
it holds internally the number for rules created and holds an array
where each cell points the to a flow rule.

From the consumers (of mlx5_add_flow_rule) point of view this
change is only cosmetic and requires only to change the type
of the returned value they store.

From the core point of view, we now need to use a loop when

The TSAR is a consist two main features:
1) BW Allocation between agents:
The TSAR implements a defecit weighted round robin between the agents.
Each agent attached to the TSAR is assigned with a weight and it is
awarded transmission tokens according to this weight.
2) Rate limer per agent:

The recent changes, which forced the registration of the boot cpu on UP
systems, which do not have ACPI tables, have been fixed for systems w/o
local APIC, but left a wreckage for systems which have neither ACPI nor
mptables, but the CPU has an APIC, e.g. virtualbox.

The boot process crashes in prefill_possible_map() as it wants to register
the boot cpu, which needs to access the local apic, but the local APIC is
not yet mapped.

There is no reason why init_apic_mapping() can't be invoked before
prefill_possible_map(). So instead of playing another silly early mapping
game, as the ACPI/mptables code does, we just move init_apic_mapping()
before the call to prefill_possible_map().

In hindsight, I should have noticed that combination earlier.

Sorry for the churn (also in stable)!
