This patch refactors Rx and Tx queue setup flow required to allow
odd number of queues to be configured in next patch.
This is the first patch of the series required to fix an issue
where qede port initialization in ovs-dpdk fails due to 1 Rx/Tx queue
configuration. Detailed explaination is given in next patch.
Fixes: 2af14ca79c0a ("net/qede: support 100G")

To: dev; +Cc: rmody, jerinj, GR-Everest-DPDK-Dev, stable
As per HW design of 100Gb mode, device internally uses 2 engines
(eng0 and eng1), and both engines need to be configured symmetrically.
Based on this requirement, driver design chose an approach
to allow user to allocate only even number of queues and split
those queues on both engines equally.
This approach puts a limitation on number of queues to be allocated -
i.e. user can't configure odd number of queues on 100Gb mode.
OVS configures DPDK port with 1 rxq and 1 txq, which causes initialization
of qede port to fail.
Issue is fixed by changing the implementation of queue allocation and
assignment to hw engines only for 100Gb devices and allowing user to
configure odd number queues.
New approach works as below -
- Create 'struct qede_fastpath_cmt' to hold hw queue pair of both engines
and provide it to rte_ethdev's Rx/Tx queues structure.
- So ethdev will see only one queue for underlying queue pair created for
hw engine pair.
- Install separate Rx/Tx data path handlers for 100Gb mode and regular mode
- Rx/Tx handlers for 100Gb mode will split packet processing across both
engines by providing hw queue structures from 'struct qede_fastpath_cmt'
passed by Rx/Tx callbacks to respective engines.

With old design, RETA was configured in round-robin fashion since
queue allocation was distributed across both engines alternately.
Now, we need to configure RETA symmetrically on both engines since
both engines have same number of queues.

As per new method, need to consider hw stats of queues from
both engines. This patch fixes the stats collection flow accordingly.

Add support to configure drop action in rte_flow
infrastructure and add counter for dropped
packets due to this filter action "rx_gft_filter_drop".
Also, update supported flows and actions in qede guide.
