Currently, the seed of the LAG hash function is always set to 0, which
means it is identical across all switches. Instead, use a random number.
This is especially important now that VxLAN is supported, as the LAG
hash function is used to calculate the UDP source port of the
encapsulated packet.

The device has the ability to flush all the FDB records that perform NVE
encapsulation or only a subset of these with a specific filtering
identifier (FID).
Expose these types so that they could be used by subsequent patches
where we need to flush the FDB records when an NVE device is unlinked
from a bridge (FID).

When the device needs to flood an overlay packet to remote VTEPs it
retrieves a pointer to the head of a linked-list of records that store
the IP addresses of these VTEPs.
These records are stored in the KVD linear memory and configured via the
Tunneling NVE Underlay Multicast Table (TNUMT) register.
Add a new KVD linear entry type for these records, so that we will be
able to allocate and free them.

mlx5e netdevice used to calculate fragment edges by a call to
mlx5_wq_cyc_get_frag_size(). This calculation did not give the correct
indication for queues smaller than a PAGE_SIZE, (broken by default on
PowerPC, where PAGE_SIZE == 64KB). Here it is replaced by the correct new
calls/API.
Since (TX/RX) Work Queues buffers are fragmented, here we introduce
changes to the API in core driver, so that it gets a stride index and
returns the index of last stride on same fragment, and an additional
wrapping function that returns the number of physically contiguous
strides that can be written contiguously to the work queue.
This obsoletes the following API functions, and their buggy
usage in EN driver:
* mlx5_wq_cyc_get_frag_size()
* mlx5_wq_cyc_ctr2fragix()
The new API improves modularity and hides the details of such
calculation for mlx5e netdevice and mlx5_ib rdma drivers.
New calculation is also more efficient, and improves performance
as follows:
Packet rate test: pktgen, UDP / IPv4, 64byte, single ring, 8K ring size.
Before: 16,477,619 pps
After: 17,085,793 pps

The current design of mlx5e driver ignores the netdevice TX/RX queues
number for netdevices that RDMA IPoIB ULP creates. Instead, the queue
number is initialized to the maximum number that mlx5 thinks best for
performance. As a result, ULP drivers that choose to create a netdevice
with queue number that is less than the maximum channels mlx5 creates,
will get a memory corruption.
This fix changes the mlx5e netdev logic to respect ULP netdevices TX/RX
queue number and use it when creating resources instead of the maximum
channel number.

netdev has several interfaces that expect to call alloc_netdev_mqs from
the core code, with the driver only providing the arguments. This is
incompatible with the rdma_netdev interface that returns the netdev
directly.
Thus re-organize the API used by ipoib so that the verbs core code calls
alloc_netdev_mqs for the driver. This is done by allowing the drivers to
provide the allocation parameters via a 'get_params' callback and then
initializing an allocated netdev as a second step.

Added support in RVU AF driver to register for
CGX LMAC link status change events from firmware
and managing them. Processing part will be added
in followup patches.
- Introduced eventqueue for posting events from cgx lmac.
Queueing mechanism will ensure that events can be posted
and firmware can be acked immediately and hence event
reception and processing are decoupled.
- Events gets added to the queue by notification callback.
Notification callback is expected to be atomic, since it
is called from interrupt context.
- Events are dequeued and processed in a worker thread.
