946dfd18a4 net/qede: convert to new Rx/Tx offloads API
Ethdev RX/TX offloads API has changed since:
commit ce17eddefc ("ethdev: introduce Rx queue offloads API")
commit cba7f53b71 ("ethdev: introduce Tx queue offloads API")

This patch makes use of new offload flags as suggested and fix
the default RX/TX configuration. Also indent the code properly
around those changes.

9e33430517 net/qede: fix MTU set and max Rx length
This patch fixes issues related to MTU set and max_rx_pkt_len usage.
 - Adjust MTU during device configuration when jumbo is enabled

 - In qede_set_mtu():
   Return not supported for VF as currently we do not support it.

   Cache new mtu value in mtu_new for proper update.

   Add check for RXQ allocation before calculating RX buffer size
   if not allocated defer RX buffer size calculation till RXQ setup.

   Add check for before performing device start/stop.

 - Use max_rx_pkt_len appropriately

 - Change QEDE_ETH_OVERHEAD macro to adjust driver specifics

aab2161750 net/qede: add Tx offloads for MPLS-in-UDP packets
Add support for inner/outer L3/L4 TX csum offload for MPLS-in-UDP packets.
The driver checks for PKT_TX_TUNNEL_MPLSINUDP in Tx ol_flags and updates TX
BD elements with appropriate offsets/length of tunnel headers.
The pseudo csum calculation is removed from qede_xmit_prep_pkts() since its
not needed.

4c4bdadfa9 net/qede: refactoring multi-queue implementation
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.

1ef4c3a5c1 net/qede: prevent crash while changing MTU dynamically
The driver can handle dynamic MTU change without needing the port to be
stopped explicitly by the application. However, there is currently no
check to prevent I/Os from happening on a different thread while the
port is going thru' reset internally. This patch fixes this issue by
assigning RX/TX burst functions to a dummy function and also reconfigure
RX bufsize for each rx queue based on the new MTU value.

a55e422e4e net/qede/base: make L2 queues handle based
L2 handler changes:

This is change to remove the queue-id/qzone difference for Tx queues.

It does that by mainly doing:

a. VFs queues are no longer determined by the SBs they're using.
Instead, the ecore-client needs to maintain those and choose the values
to be used by VF when initializing it.

b. Eliminate the HW-cid array in the hw-function.
To do that, have all the rx/tx functionality turn into 'handle' base -
when queue would be started the caller would get a (void*) handle,
which it would later use with ecore for configuring various
queue-related stop [update, close].

dbac54c2d3 net/qede: fix port (re)configuration
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.
