ca041cd44f ethdev: change allmulticast callbacks to return status
Enabling/disabling of allmulticast mode is not always successful and
it should be taken into account to be able to handle it properly.

When correct return status is unclear from driver code, -EAGAIN is used.

9970a9ad07 ethdev: make stats and xstats reset callbacks return int
Change return value of the callbacks from void to int. Make
implementations across all drivers return negative errno
values in case of error conditions.

Both callbacks are updated together because a large number of
drivers assign the same function to both callbacks.

164cad78b0 net/mlx4: fix crash on info query in secondary process
mlx4_dev_info_get calls mlx4_get_ifname, but mlx4_get_ifname
uses priv->ctx which is not a valid pointer in a secondary
process. The fix is to cache the value in primary.

In the primary process, get and store the interface index of
the device so that secondary process can see it.

138a740c45 net/mlx4: support multicast address list interface
Since this driver does not distinguish unicast/multicast addresses,
applications could always rely on the standard MAC add/remove/set
interface to configure both types.

As a result, the multicast address list interface never got implemented
(rte_eth_dev_set_mc_addr_list()) however PMD-agnostic applications still
rely on it for compatibility reasons; a wrapper is therefore required.

78214fb882 net/mlx4: fix Rx packet type offloads
This patch improves Rx packet type offload report in case the device is
a virtual function device.
In these devices we observed that the L2 tunnel flag is set also for
non-tunneled packets, this leads to a complete misinterpretation of the
packet type being received.
This issue occurs since the tunnel_mode is not set to 0x7 by the driver
for virtual devices and therefore the value in the L2 tunnel flag is
meaningless and should be ignored.

078b8b452e net/mlx4: add RSS flow rule action support
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.

67e6cce675 net/mlx4: update Rx/Tx callbacks consistently
Although their "removed" version acts as a safety against unexpected bursts
while queues are being modified by the control path, these callbacks are
set per device instead of per queue. It makes sense to update them during
start/stop/close cycles instead of queue setup.

As a side effect, this commit addresses a bug left over from a prior
commit: bringing the link down causes the "removed" Tx callback to be used,
however the normal callback is not restored when bringing it back up,
preventing the application from sending traffic at all.

Updating callbacks for a link change is not necessary as bringing the
netdevice down is normally enough to prevent traffic from flowing in.

30695adbdd net/mlx4: add VLAN filter configuration support
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.

return an error in case of failure at stats getting process time.

Since PCI devices can be removed and there is a time between the
physical removal to the RMV interrupt, the user may get invalid stats
without any indication.

This patch changes the stats_get API return value to be int instead of
void.

All the net PMDs stats_get dev ops are adjusted by this patch.

be65fdcbfb net/mlx4: rely on ethdev for Tx/Rx queue arrays
Allocation and management of Tx/Rx queue arrays is done by wrappers at the
ethdev level. The resulting information is copied to the private structure
while configuring the device, where it is managed separately by the PMD.

This is redundant and consumes space in the private structure.

Relying more on ethdev also means there is no need to protect the PMD
against burst function calls while closing the device anymore.

61cbdd4194 net/mlx4: separate device control functions
Private functions are now prefixed with "mlx4_" to prevent them from
conflicting with their mlx5 PMD counterparts at link time.

No impact on functionality.
