The name "mrvl" for Marvell PMD driver for PPv2 Marvell PPv2
(Packet Processor v2) 1/10 Gbps adapter is too generic and causes
problem for adding new PMD drivers for other Marvell devices.
Changed to "mvpp2" for specific Marvell PPv2 PMD.
This patch doesn't introduce any change except renaming.

Enable rx queue interrupts if the app requests them, and vNIC has
enough interrupt resources. Use interrupt vector 0 for link status and
errors. Use vector 1 for rx queue 0, vector 2 for rx queue 1, and so
on. So, with n rx queues, vNIC needs to have at n + 1 interrupts.
For VIC, enabling and disabling rx queue interrupts are simply
mask/unmask operations. VIC's credit based interrupt moderation is not
used, as the app wants to explicitly control when to enable/disable
interrupts.
This version requires MSI-X (vfio-pci). Sharing one interrupt for link
status and rx queues is possible, but is rather complex and has no
user demands.

Currently, when more than 1 receive queues are configured, the driver
always enables RSS with the driver's own default hash type, key, and
RETA. The user is unable to change any of the RSS settings. Address
this by implementing the ethdev RSS API as follows.
Correctly report the RETA size, key size, and supported hash types
through rte_eth_dev_info.
During dev_configure(), initialize RSS according to the device's
mq_mode and rss_conf. Start with the default RETA, and use the default
key unless a custom key is provided.
Add the RETA and rss_conf query/set handlers to let the user change
RSS settings after the initial configuration. The hardware is able to
change hash type, key, and RETA individually. So, the handlers change
only the affected settings.
Refactor/rename several functions in order to make their intentions
clear. For example, remove all traces of RSS from
enicpmd_vlan_offload_set() as it is confusing.

This patch is the last patch in the series of patches aimed
to add support for registering and waiting for Rx interrupts
in failsafe PMD. This allows applications to wait for Rx events
from the PMD using the DPDK rte_epoll subsystem.
The failsafe PMD presents to the application a facade of a single
device to be handled by the application while internally it manages
several devices on behalf of the application including packets
transmission and reception.
The Proposed failsafe Rx interrupt scheme follows this approach.
The failsafe PMD will present the application with a single set of
Rx interrupt vectors representing the failsafe Rx queues, while
internally it will serve as an interrupt proxy for its subdevices.
will allow applications to wait for Rx traffic from the failsafe
PMD by registering and waiting for Rx events from its Rx queues.
In order to support this the following is suggested:
* Every Rx queue in the failsafe (virtual) device will be assigned
* a Linux event file descriptor (efd) and an enable_interrupts flag.
* The failsafe PMD will fill in its rte_intr_handle structure with
the Rx efds assigned previously and register them with the EAL.
* The failsafe driver will create a private epoll fd (epfd) and
* will allocate enough space to handle all the Rx events from all its
subdevices.
* Acting as an application,
for each Rx queue in each active subdevice the failsafe will:
o Register the Rx queue with the EAL.
o Pass the EAL the failsafe private epoll fd as the epfd to
register the Rx queue event on.
o Pass the EAL, as a parameter, the pointer to the failsafe Rx
queue that handles this Rx queue.
o Using the DPDK service callbacks, the failsafe PMD will launch
an Rx proxy service that will Wait on the epoll fd for Rx
events from the sub-devices.
o For each Rx event received the proxy service will
- Retrieve the pointer to failsafe Rx queue that handles
this subdevice Rx queue from the user info returned by the
EAL.
- Trigger a failsafe Rx event on that queue by writing to
the event fd unless interrupts are disabled for that queue.
* The failsafe pmd will also implement the rx_queue_intr_enable
* and rx_queue_intr_disable routines that will enable and disable Rx
interrupts respectively on both on the failsafe and its subdevices.

Ethdev Tx offloads API has changed since:
commit cba7f53b717d ("ethdev: introduce Tx queue offloads API")
This commit support the new Tx offloads API.
The code which fills in txq_flags in default_txconf is preserved
because rte_eth_dev_info_get() lacks conversion between offloads
and txq_flags fields which means that a legacy application which
relies on default_txconf will fail to configure Tx queues in the
case when some bits in txq_flags are mandatory.

This patch dissociates single-queue indirection tables and hash QP objects
from Rx queue structures to relinquish their control to users through the
RSS flow rule action, while simultaneously allowing multiple queues to be
associated with RSS contexts.
Flow rules share identical RSS contexts (hashed fields, hash key, target
queues) to save on memory and other resources. The trade-off is some added
complexity due to reference counters management on RSS contexts.
The QUEUE action is re-implemented on top of an automatically-generated
single-queue RSS context.
The following hardware limitations apply to RSS contexts:
- The number of queues in a group must be a power of two.
- Queue indices must be consecutive, for instance the [0 1 2 3] set is
allowed, however [3 2 1 0], [0 2 1 3] and [0 0 1 1 2 3 3 3] are not.
- The first queue of a group must be aligned to a multiple of the context
size, e.g. if queues [0 1 2 3 4] are defined globally, allowed group
combinations are [0 1] and [2 3]; groups [1 2] and [3 4] are not
supported.
- RSS hash key, while configurable per context, must be exactly 40 bytes
long.
- The only supported hash algorithm is Toeplitz.

This commit brings back VLAN filter configuration support without any
artificial limitation on the number of simultaneous VLANs that can be
configured (previously 127).
Also thanks to the fact it does not rely on fixed per-queue arrays for
potential Verbs flow handle storage anymore, this version wastes a lot less
memory (previously 128 * 127 * pointer size, i.e. 130 kiB per Rx queue,
only one of which actually had any use for this room: the RSS parent
queue).
The number of internal flow rules generated still depends on the number of
configured MAC addresses times that of configured VLAN filters though.
