From: Bruce Allan <bruce.w.allan@intel.com>
In ice_flow_add_prof_sync(), struct ice_flow_prof_params has recently
grown in size hogging stack space when allocated there. Hogging stack
space should be avoided. Change allocation to be on the heap when needed.

These functions are currently used to add Flow Director filters, however,
they will be expanded to also add ACL filters. Rename the functions,
replacing 'fdir' to 'ntuple', to reflect that they are being
used to for ntuple filters and are not solely used for Flow Director.

ACL filtering can be utilized to expand support of ntuple rules by allowing
mask values to be specified. Begin implementation of ACL filters by setting
up structures, AdminQ commands, and allocation of the ACL table in the
hardware.

Complete initialization of the ACL table by programming the table with an
initial scenario. The scenario stores the data for the filtering rules.
Adjust reporting of ntuple filters to include ACL filters.

Implement the initial steps for creating an ACL filter to support ntuple
masks. Create a flow profile based on a given mask rule and program it to
the hardware. Though the profile is written to hardware, no actions are
associated with the profile yet.

From: Paul M Stillwell Jr <paul.m.stillwell.jr@intel.com>
There are times when the driver shouldn't return an error when the Get
PHY abilities AQ command (0x0600) returns an error. Instead the driver
should log that the error occurred and continue on. This allows the
driver to load even though the AQ command failed. The user can then
later determine the reason for the failure and correct it.

vlan_ena was introduced to track whether VLAN filters are enabled on
the device, but
1) checking for num_vlan > 1 already gives us this information, and is
currently used in this way throughout the code
2) the logic for vlan_ena is broken when multiple VLANs are active
Just remove vlan_ena and use num_vlan instead.

Just out of curiosity, you are only re-aligning the code and not the
printed messages themselves. How would this help ? did you mean help
with tracking the sources when doing grep like operations on the source
code ?

The primary motivation is that the line number of the string now matches
the line number of the debug function statement, so there is better
alignment when using these line numbers with the dynamic debug messaging
system.
It's also a style thing, that came up on the list for some patches I
wrote for the ice flash update.. it was suggested to just keep the
message on the same line as the function. I felt that it was better to
go ahead and fix all of these files, so that future code is more likely
to use the preferred style rather than follow the pattern of older code.
Thanks,
Jake

This is a lot of code with only 2 liner commit messages!
Can you please shed more light on what user interface is being used to
program and manage those ACLs, i see it is ethtool from the code but
the cover letter and commit messages do not provide any information
about that.
Also could you please explain what ethtool interfaces/commands are
being implemented, in the commit messages or cover letter, either is
fine.
Thanks!

Please remove the defensive programming checks, and preferably slim
down the use of your special return codes.
