There were defines which originally allowed sharing of some code with
the enic kernel driver. The code has long since diverged and now the
abstraction just makes the code harder to read. Mostly mechanical
replacement of defines and reformatting.

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.

Latest firmware supports Geneve with options offload. Current overlay
offload only supports Geneve with no options. This new feature is
disabled by default, as it is intrusive and cannot be used with flow
API. Add a new devarg 'geneve-opt' so the user can explicitly enable
it.

The firmware in 1400 series VIC adapters which would support COUNT
flow action was postponed and reworked. The capability will be
re-added in a future release when the firmware is available.
This reverts the following commits.

- track whether counter DMAs are active or not so they can be stopped if
needed before DMA memory is freed
- fix counter DMA shut-down by changing vnic_dev_counter_dma_cfg() to
take the number of counters to DMA instead of high counter index and
use num counters = 0 to shut off DMAs
- remove unnecessary checks that DMA counter memory is valid and that
counter DMAs are in use
- change the minimum DMA period to match what 1400 series adapter is
capable of
- fix comments and change a couple variable names to make more sense

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.

The UDP RSS interface has changed in the release firmware for 100G VIC
adapters. The capability bit is now in NIC_CFG. Also the driver is
supposed to use CMD_NIC_CFG_CHK and check if RSS config is
successful. No more changes are expected with respect to UDP RSS API.

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.
