net/dpaa2: fix the Tx handling of non HW pool bufs

The current code is sending 8 packet in each internal loop.
In some of the conditions, mbuf is being allocated or freed.
In case of error, the code is returning without taking care of
such buffer. It is better to send already prepared buffer and err
for the current failure only.

net/tap: allow RSS flow action

One of the main identified use cases for the tap PMD is to be used in
combination with the fail-safe PMD as a fallback for a physical device.

Fail-safe is very strict about making sure its current configuration is
properly applied to all slave devices, they get rejected otherwise in
order to maintain a consistent state.

The problem is that tap's RSS support is currently limited to the
default (non-Toeplitz) balancing performed by the kernel on all Rx
queues. While proper RSS support emulation in the tap PMD is a work in
progress, the lack of rte_flow counterpart prevents validation of the
above use case in the meantime.

Given that unlike most PMDs, tap is more about convenience than
performance, support for the RSS action can be temporarily faked with
a minimum amount of code and mostly correct behavior by treating it
like a QUEUE action. Traffic is directed to the first queue of the set.

In the new API, offloads are divided into per-port and per-queue
offloads. The PMD reports capability for each of them.
Offloads are enabled using the existing DEV_TX_OFFLOAD_* flags.
To enable per-port offload, the offload should be set on both device
configuration and queue configuration. To enable per-queue offload, the
offloads can be set only on queue configuration.

In addition the Tx offloads will be disabled by default and be
enabled per application needs. This will much simplify PMD management of
the different offloads.

Applications should set the ETH_TXQ_FLAGS_IGNORE flag on txq_flags
field in order to move to the new API.

The old Tx offloads API is kept for the meanwhile, in order to enable a
