70041088e3 RDS: Add TCP transport to RDS
This code allows RDS to be tunneled over a TCP connection.

RDMA operations are disabled when using TCP transport,
but this frees RDS from the IB/RDMA stack dependency, and allows
it to be used with standard Ethernet adapters, or in a VM.

618952a7b1 mwl8k: fix firmware command serialisation
The current mwl8k_priv->fw_lock spinlock doesn't actually protect
against multiple commands being submitted at once, as it is not kept
held over the entire firmware command submission.  And since waiting
for command completion sleeps, we can't use a spinlock anyway.

To fix mwl8k firmware command serialisation properly, we have the
following requirements:
- Some commands require that the packet transmit path is idle when
  the command is issued.  (For simplicity, we'll just quiesce the
  transmit path for every command.)
- There are certain sequences of commands that need to be issued to
  the hardware sequentially, with no other intervening commands.

This leads to an implementation of a "firmware lock" as a mutex that
can be taken recursively, and which is taken by both the low-level
command submission function (mwl8k_post_cmd) as well as any users of
that function that require issuing of an atomic sequence of commands,
and quiesces the transmit path whenever it's taken.

950d5b0191 mwl8k: mwl8k_queue_work() cleanup
Delete most of the mwl8k_work_struct fields and options, since most
of them are unused or never changed from their defaults:
- We always use priv->config_wq, so delete the wqueue argument from
  mwl8k_queue_work().
- MWL8K_WQ_SPIN and MWL8K_WQ_POST_REQUEST are never used, as all
  callers sleep for request completion, so sleep unconditionally.
- MWL8K_WQ_FREE_WORKSTRUCT is never used.
- MWL8K_WQ_TX_WAIT_EMPTY is always set, so assume it unconditionally.
- timeout_ms/txwait_attempts/tx_timeout_ms are never changed from
  their defaults, so just hardcode these in the workqueue worker.
- step is never used.

23b339062f mwl8k: mwl8k_txq_xmit() rework
Various mwl8k_txq_xmit changes:
- Extract the QoS field before adding the DMA header.
- Only write to tx->status once, and only after all the other
  descriptor fields have been set.
- Do all tx state manipulation under the tx spinlock.
- Remove the priv->inconfig check, as all transmit queues will
  be frozen during config cycles, so we won't ever be asked to
  transmit if a config cycle is running.
- Remove some more dead code.

Since firmware load commands don't generate 'command done' interrupts

unnecessarily slows down the firmware load process.  Removing this bit

180 msec.

76266b2ad3 mwl8k: dma header manipulations can't fail
Adding and removing the DMA header that the mwl8k hardware requires
on tx and provides on rx can never fail, since we are guaranteed to
have enough headroom on the tx path to expand the packet, and we only
ever shrink the packet on the rx path.  (And on both paths we are
guaranteed to be the only user of the skb we are handling.)

This allows removing all of the skb clone handling in the tx and tx
reclaim paths, and eliminates error checks in both the tx and rx
paths, simplifying the code a bit more.

e81cd2d664 mwl8k: fix mwl8k_configure_filter() parameter lifetime issue
mwl8k_configure_filter() passes pointers to total_flags and the
multicast address list to a workqueue function, while there is no
guarantee that those pointers will still be valid by the time the
workqueue function runs.

Solve this by passing total_flags by value, and by passing an
already built multicast address setup command packet to the workqueue
function so that we don't have to look at the multicast address list
itself outside of mwl8k_configure_filter().

Also, since ->configure_filter() can sleep now, wait synchronously
for the worker to finish.
