net/enic: use 64B completion queue entries if available

Latest VIC adapters support 64B CQ (completion queue) entries as well
as 16B entries available on all VIC models. 64B entries can greatly
reduce cache contention (CPU stall cycles) between DMA writes (Rx
packet descriptors) and polling CPU. The effect is very noticeable on
Intel platforms with DDIO. As most UCS servers are based on Intel
platforms, enable and use 64B CQ entries by default, if
available. Also, add devarg 'cq64' so the user can explicitly disable
64B CQ.

net/enic: add flow implementation based on Flow Manager API

Flow Manager API is the new firmware interface that exposes match
action capabilities in 1400 series VIC adapters. It is intended for
virtual switch offloads and enables more advanced features than the
existing filter API. For example, it supports VXLAN encap and decap
actions, and exposes TCAM and exact match tables.

Add the new flow implementation using Flow Manager and use it when
available. When Flow Manager is not available, the driver will
continue to use the old filter-based flow implementation.

- fix counter DMA shut-down by changing vnic_dev_counter_dma_cfg() to

counter DMAs are in use

Support counter action for 1400 series adapters.

The adapter API for allocating and freeing counters is independent of
the adapter match/action API. If the filter action is requested, a
counter is first allocated and then assigned to the filter, and when
the filter is deleted, the counter must also be deleted.

Counters are DMAd to pre-allocated consistent memory periodically,
controlled by the define VNIC_FLOW_COUNTER_UPDATE_MSECS. The default is
100 milliseconds.

net/enic: enable overlay offload for VXLAN and GENEVE

Recent NIC models support overlay offload. The overlay offload
feature enables the following on the NIC.
- Rx/Tx checksum offloads for both inner and outer packets.
- Rx inner packet type classification.
- TSO.
- Inner RSS.

TX descriptors do not require any changes, except the header length
for TSO. The NIC parses outer/inner packets and performs offloads on
them as necessary. The header length for tunneled TSO includes both
inner and outer headers.

The NIC actually parses and performs the above for NVGRE as well. DPDK
currently has no offload flags for NVGRE, and the hardware has no
controls to individually enable tunnel types either. So do nothing for
now.

The driver enables overlay offload by default. Add a devargs
'disable-overlay=<0|1>' to allow the app to disable it.

Also update the enic guide doc.
