Methods sometimes need to get a flexible set of IDRs and not a strict set
as can be achieved today by the conventional IDR attribute. Add a new
IDRS_ARRAY attribute to the generic uverbs ioctl layer.
IDRS_ARRAY points to array of idrs of the same object type and same access
rights, only write and read are supported.

The upstream kernel commit cited below modified the workqueue in the
new CQ API to be bound to a specific CPU (instead of being unbound).
This caused ALL users of the new CQ API to use the same bound WQ.
Specifically, MAD handling was severely delayed when the CPU bound
to the WQ was busy handling (higher priority) interrupts.
This caused a delay in the MAD "heartbeat" response handling,
which resulted in ports being incorrectly classified as "down".
To fix this, add a new "unbound" WQ type to the new CQ API, so that users
have the option to choose either a bound WQ or an unbound WQ.
For MADs, choose the new "unbound" WQ.

Inside of start_xmit() the call to check if the connection is up and the
queueing of the packets for later transmission is not atomic which leaves
a window where cm_rep_handler can run, set the connection up, dequeue
pending packets and leave the subsequently queued packets by start_xmit()
sitting on neigh->queue until they're dropped when the connection is torn
down. This only applies to connected mode. These dropped packets can
really upset TCP, for example, and cause multi-minute delays in
transmission for open connections.
Here's the code in start_xmit where we check to see if the connection is
up:
if (ipoib_cm_get(neigh)) {
if (ipoib_cm_up(neigh)) {
ipoib_cm_send(dev, skb, ipoib_cm_get(neigh));
goto unref;
}
}
The race occurs if cm_rep_handler execution occurs after the above
connection check (specifically if it gets to the point where it acquires
priv->lock to dequeue pending skb's) but before the below code snippet in
start_xmit where packets are queued.
if (skb_queue_len(&neigh->queue) < IPOIB_MAX_PATH_REC_QUEUE) {
push_pseudo_header(skb, phdr->hwaddr);
spin_lock_irqsave(&priv->lock, flags);
__skb_queue_tail(&neigh->queue, skb);
spin_unlock_irqrestore(&priv->lock, flags);
} else {
++dev->stats.tx_dropped;
dev_kfree_skb_any(skb);
}
The patch acquires the netif tx lock in cm_rep_handler for the section
where it sets the connection up and dequeues and retransmits deferred
skb's.

Pull Flow actions to mutate packets from Leon Romanovsky:
====================
This series exposes the ability to create flow actions which can
mutate packet headers. We do that by exposing two new verbs:
* modify header - can change existing packet headers. packet
* reformat - can encapsulate or decapsulate a packet.
Once created a flow action must be attached to a steering
rule for it to take effect.
The first 10 patches refactor mlx5_core code, rename internal structures
to better reflect their operation and export needed functions so the RDMA
side can allocate the action.
The last 5 patches expose via the IOCTL infrastructure mlx5_ib methods
which do the actual allocation of resources and return an handle to the
user. A user of this API is expected to know how to work with the device's
spec as the input to those function is HW depended.
An example usage of the modify header action is routing, A user can create
an action which edits the L2 header and decrease the TTL.
An example usage of the packet reformat action is VXLAN encap/decap which
is done by the HW.

that the data passed in can be represented by the type the user supplies.
The expectation is this will always be used with an enum declaring the
constant values, and the user will use the enum type as input to the
accessor.
To retrieve the attribute value we introduce two helper calls - one
standard which may fail if attribute is not valid and one where caller can
provide a default value which will be used in case the attribute is not
valid (useful when attribute is optional).
