This patch fixes VF MTU update to work without having to restart the
vport and there by not requiring port re-configuration. It adds a
VF MTU Update TLV to achieve the same. Firmware can handle VF MTU update
by just pausing the vport.

Few adjustments are required to effectively handle VF vport create/delete
sequence. The problem is exposed by recent ethdev TX offload changes
which requires port to be in down state before applying TX offloads.
- Move vport creation from dev_init() to dev_configure()
- Force to stop vport if it was already started due to previous run
(restart case)
- Move link state enable/disable to dev_init() and dev_close()
respectively.
- For MTU change, recreate vport with new MTU value and restore old
config. This is necessary since VF MTU value can be changed only upon
vport creation.

Create a rte_ethdev_driver.h file and move PMD specific APIs here.
Drivers updated to include this new header file.
There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.
More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

This patch adds support for handling run-time driver arguments.
We have removed config option for per VF Tx switching and added
a run-time argument vf_txswitch. By default, the VF Tx switching is
enabled however it can be disabled using run-time argument.
Sample usage to disable per port VF Tx switching is something like...
-w 05:00.0,vf_txswitch=0 -w 05:00.1,vf_txswitch=0

This patch does the following refactoring and cleanup:
- As part of multi-queue support a struct member called 'type' was added
in struct qede_fastpath in order to identify whether a queue is RX or
TX and take actions based on that. This was unnecessary in the first
place since pointers to RX and TX queues are already available in
rte_eth_dev->data. So all usage of fp->type is removed.
- Remove remaining additional layer of internal callbacks for RX/TX
queues and fastpath related operations from the qed_eth_ops_pass.
With this change the files qede_eth_if.[c,h] are no longer needed.
- Add new per-queue start/stop APIs instead of clubbing it all together.
- Remove multiple TXQs references (num_tc and fp->txqs) since CoS is not
supported.
- Enable sharing of the status block for each queue pair.
- Remove enum qede_dev_state and instead make use of existing port
states RTE_ETH_QUEUE_STATE_STOPPED/RTE_ETH_QUEUE_STATE_STARTED.
- Move qede_dev_start() and qede_dev_stop() to qede_ethdev.c from
qede_rxtc.c.

The refactoring is mainly for two reasons:
- To remove an additional layer of internal callbacks for all vport
related operations from the struct qed_eth_ops_pass. Instead, we
can invoke base APIs directly.
- Splitting a single large vport-update configuration into multiple and
independent vport-update operations. Each configuration would touch
only the required config bits that needs an update.

The newer SR-IOV PF drivers expects RX/TX queues to be created before

deferring RSS configuration till the queues are created. Even though
this issue is only seen in SR-IOV context, the changes will be made
applicable to PF also to keep the behavior consistent between VF/PF.

In qede_mac_addr_add() a check is added to differentiate between
unicast/multicast mac to prevent a multicast mac from being wrongly added
to unicast filter table. Secondly, two separate lists will be used to keep
track of unicast/multicast mac filters to prevent duplicate filter
programming. The other change is to remove filter_config from struct
qed_eth_ops_pass and invoke the base APIs directly. This avoids the need
to have multiple structs and function calls.

The device doesn't explicitly support enable/disable
of VLAN filtering. However, VLAN filtering takes effect
when a matching VLAN is configured. So in order to
support enable/disable of VLAN filtering, VLAN 0 is
added/removed respectively. A check is added to ensure that
the user removes all the configured VLANs before disabling
VLAN filtering.
Also VLAN offloads shall be enabled by default and
vlan_tci_outer is to set to 0 for Q-in-Q packets.

Some applications set port configuration params like promisc mode
before calling dev_start(). This config results in a firmware exception
since this operation internally translates to sending of VPORT-UPDATE
before VPORT-START ramrod which is considered illegal from firmware
standpoint. So the fix is to send VPORT-START ramrod sooner
in dev_configure() rather than deferring it to dev_start().
This requires a bit of reshuffling in the code to move sending of
VPORT-START from qede_start_queues() to qede_dev_configure()
and VPORT-STOP from qede_stop_queues() to qede_dev_stop().
This sequence change also exposes a flaw in the port restart
flows where the fastpath resource allocation routine qede_init_fp()
functionalities need to be split, so that appropriate action is taken
based on the current port state. Eg: Do not re-initialize the status
block in a port restart case. This change ensures port start/stop
can be paired.
A new port state QEDE_DEV_CONFIG is added to distinguish between
port started from scratch vs port requiring a reconfig (like MTU).
The function qede_config_rx_mode() is removed since the individual
port config will be replayed anyways on a restart.
