Convert and try to standardize bit fields using
GENMASK/FIELD_PREP/FIELD_GET macros. Rework some logic to support the
standard macro and tidy things up. No functional change intended.

I still need to test this in every part but I would like to have some
approval about this kind of change. Also there are tons of warning by
checkpatch about too long line... Are they accepted for headers? I can't
really find another way to workaround the problem as reducing the define
name would make them less descriptive.
Aside from that I did the conversion as carefully as possible so in
theory nothing should be broken and the conversion should be all
correct. Some real improvement by using filed macro are in the
fdb_read/fdb_write that now are much more readable.

My main concern is that it is going to be a tad harder to back port
fixes made to this driver with such changes in place, so unfortunately
it is usually a matter of either the initial version of the driver use
BIT(), FIELD_{PREP,GET} and GENMASK, or the very few commits following
the initial commit take care of that, and then it is all rosy for
everyone, or else it may be complicated.
You are one of the active contributors to this driver, so ultimately you
should decide.

Problem I'm trying to solve here is that I notice various name scheme
used and not an unique one... (many _S and _M mixed with MASK and SHIFT)
Various shift and strange bits handling. I think this is needed to
improve the code in all the next release.
About backports you mean for older kernel (bugfixes) or for external
project (backports for openwrt, for example?) Anyway in the main code
(the one in theory that should receive backports) I just reworked the ACL
code that should be stable and the switch ID handling (I don't think
there is anything to fix there). Aside from that and some improvement to
VLAN, I tried to implement FIELD_PREP only in the define without
touching qca8k code.
I honestly don't know if this would cause that much of a problem with
backports (assuming they only touch qca8k code and not header).
Would love to receive some feedback if I'm wrong about my idea.
Any feedback about the warning for long names in the define? Are they
accepted? I can't find anywhere how we should handle them.

While it does look pretty ugly, and you could perhaps split them like
this:
#define QCA8K_VTU_FUNC0_EG_MODE_PORT_MASK(_i) \
(GENMASK(1, 0) << QCA8K_VTU_FUNC0_EG_MODE_PORT_SHIFT(_i))
it's more or less a judgement call, I've seen worse in a header file,
and exceeding a certain line length is certainly not among the worst of
sins - putting complex control flow logic inside the C preprocessor
would take that place, I think.
Anyway, Florian's point is that you're touching up the following
functions:
qca8k_port_vlan_filtering
qca8k_port_vlan_add
qca8k_read_switch_id
qca8k_setup
qca8k_vlan_del
qca8k_vlan_add
qca8k_vlan_access
qca8k_fdb_access
qca8k_fdb_write
qca8k_fdb_read
quite gratuitously, but this is another judgement call for you to make.
The only thing you should consider is that future you might hate you for
giving him extra work when a new bug in those functions is discovered.
You'll have to prepare a fix patch that applies on the refactored code,
to submit to the "net" tree, and and a fix patch that applies to the
pre-refactoring code, to submit to the "stable" tree directly.
As a proponent of code cleanups myself, I would still choose to do the
refactoring, but just be aware that it doesn't come for free.
