net: intel: Use *-y instead of *-objs in Makefile

*-objs suffix is reserved rather for (user-space) host programs while
usually *-y suffix is used for kernel drivers (although *-objs works
for that purpose for now).

Let's correct the old usages of *-objs in Makefiles.

i40e: Implement DDP support in i40e driver

This patch introduces DDP (Dynamic Device Personalization) which allows
loading profiles that change the way internal parser interprets processed
frames. To load DDP profiles it utilizes ethtool flash feature. The files
with recipes must be located in /var/lib/firmware directory. Afterwards
the recipe can be loaded by invoking:

ethtool -f <if_name> <file_name> 100
ethtool -f <if_name> - 100

See further details of this feature in the i40e documentation, or
visit
https://www.intel.com/content/www/us/en/architecture-and-technology/ethernet/dynamic-device-personalization-brief.html

The driver shall verify DDP profile can be loaded in accordance with
the rules:
* Package with Group ID 0 are exclusive and can only be loaded the first.
* Packages with Group ID 0x01-0xFE can only be loaded simultaneously
with the packages from the same group.
* Packages with Group ID 0xFF are compatible with all other packages.

i40e: add AF_XDP zero-copy Rx support

This patch adds zero-copy Rx support for AF_XDP sockets. Instead of
allocating buffers of type MEM_TYPE_PAGE_SHARED, the Rx frames are
allocated as MEM_TYPE_ZERO_COPY when AF_XDP is enabled for a certain
queue.

All AF_XDP specific functions are added to a new file, i40e_xsk.c.

Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS
will allocate a new buffer and copy the zero-copy frame prior passing
it to the kernel stack.

i40e/i40evf: Add tracepoints

This patch adds tracepoints to the i40e and i40evf drivers to which
BPF programs can be attached for feature testing and verification.
It's expected that an attached BPF program will identify and count or
log some interesting subset of traffic. The bcc-tools package is
helpful there for containing all the BPF arcana in a handy Python
wrapper. Though you can make these tracepoints log trace messages, the
messages themselves probably won't be very useful (other to verify the
tracepoint is being called while you're debugging your BPF program).

The idea here is that tracepoints have such low performance cost when
disabled that we can leave these in the upstream drivers. This may
eventually enable the instrumentation of unmodified customer systems
should the need arise to verify a NIC feature is working as expected.
In general this enables one set of feature verification tools to be
used on these drivers whether they're built with the kernel or
separately.

Users are advised against using these tracepoints for anything other
than a diagnostic tool. They have a performance impact when enabled,
and their exact placement and form may change as we see how well they
work in practice for the purposes above.

i40e: Drop FCoE code from core driver files

Looking over the code for FCoE it looks like the Rx path has been broken at
least since the last major Rx refactor almost a year ago. It seems like
FCoE isn't supported for any of the Fortville/Fortpark hardware so there
isn't much point in carrying the code around, especially if it is broken
and untested.

We export three controls:
min_bw - Can take a value from 0 to 100 inclusive
max_bw - Can take a value from 1 to 100 inclusive
commit - A write-only control that accepts only a value of 1 and will
cause the BW settings to be permanently committed to NVM so
that they are persistent across power cycles and system
resets

The BW values are relative and are expressed as percentages. For more
information on the interpretation of the BW settings see the Dell
specifications for NPAR.
