mbuf: clarify outer offsets for non-tunnel packets

The default policy for offload-specific fields is that
they are undefined unless the corresponding offloads are
requested in mbuf ol_flags. This is also the case for outer
L2 and L3 length fields which must not be assumed to contain
zeros for non-tunnel packets. The patch clarifies this behaviour
in the comments and also adds appropriate checks to the PMDs which
do not check any tunnel-related offloads before using the said fields.

net: fix how L4 checksum choice is tested

The API to prepare checksum offloads mistreats L4

Turning these flag checks into enum checks causes

net/pcap: enable infinitely Rx a pcap file

It can be useful to use pcap files for some rudimental performance
testing. This patch enables this functionality in the pcap driver.

At a high level, this works by creating a ring of sufficient size to
store the packets in the pcap file passed to the application. When the
rx function for this mode is called, packets are dequeued from the ring
for use by the application and also enqueued back on to the ring to be
"received" again.

A tx_drop mode is also added since transmitting to a tx_pcap file isn't
desirable at a high traffic rate.

Jumbo frames are not supported in this mode. When filling the ring at rx
queue setup time, the presence of multi segment mbufs is checked for.
The PMD will exit on detection of these multi segment mbufs.

net/ice/base: refactor VSI node scheduler

Refactored VSI node sched code to use port_info ptr as call arg.

The declaration of VSI node getter function has been modified to use
pointer to ice_port_info structure instead of pointer to hw structure.
This way suitable port_info structure is used to find VSI node.

net/ice/base: fix Rx functionality for ethertype filters

In the function ice_add_eth_mac(), there is a line that
hard-codes the filter info flag to TX. This is redundant
and inaccurate. That flag will be set by the calling
function that built the list of filters to add, and
hard-coding it eliminates the Rx functionality of this
code. The paired function ice_remove_eth_mac() does not
do this, making a mis-matched pair.

net/ice/base: fix DCBx initialization

When a port is not cabled, but DCBx is enabled in the firmware, the
status of DCBx will be NOT_STARTED. This is a valid state for FW
enabled and should not be treated as a is_fw_lldp true automatically.

Add the code to treat NOT_STARTED as another valid state.
