Now that commit 028fb19c6b ("netlink: provide an ability to set
default extack message") provides a weak function that doesn't override
an existing extack message provided by the driver, it makes sense to use
it also for LAG and HSR offloading, not just for bridge offloading.
Also consistently put the message string on a separate line, to reduce
line length from 92 to 84 characters.

ice_vsi_cfg() is called from different contexts:
1) VSI exsist in HW, but it is reconfigured, because of changing queues
for example -> update instead of init should be used
2) VSI doesn't exsist, because rest has happened -> init command should
be sent
To support both cases pass boolean value which will store information
what type of command has to be sent to HW.

Part of code from probe can be reused in reload flow. Move this code to
separate function. Create unroll functions for each part of
initialization, like: ice_init_dev() and ice_deinit_dev(). It
simplifies unrolling and can be used in remove flow.
Avoid freeing port info as it could be reused in reload path.
Will be freed in remove path since is allocated via devm_kzalloc().

When allocating the ICE_VSI_CTRL, the allocated struct ice_vsi pointer is
stored into the PF's pf->vsi array at a fixed location. This was
historically done on the basis that it could provide an O(1) lookup for the
special control VSI.
Since we store the ctrl_vsi_idx, we already have O(1) lookup regardless of
where in the array we store this VSI.
Simplify the logic in ice_vsi_alloc by using the same method of storing the
control VSI as other types of VSIs.

Main goal is to reuse the same functions in VSI config and rebuild
paths.
To do this split ice_vsi_setup into smaller pieces and reuse it during
rebuild.
ice_vsi_alloc() should only alloc memory, not set the default values
for VSI.
Move setting defaults to separate function. This will allow config of
already allocated VSI, for example in reload path.
The path is mostly moving code around without introducing new
functionality. Functions ice_vsi_cfg() and ice_vsi_decfg() were
added, but they are using code that already exist.
Use flag to pass information about VSI initialization during rebuild
instead of using boolean value.

Do few small cleanups:
1) Rename the function to reflect that it doesn't configure all things
related to VSI. ice_vsi_cfg_lan() better fits to what function is doing.
ice_vsi_cfg() can be use to name function that will configure whole VSI.
2) Remove unused ethtype field from VSI. There is no need to set
ethtype here, because it is never used.
3) Remove unnecessary check for ICE_VSI_CHNL. There is check for
ICE_VSI_CHNL in ice_vsi_get_qs, so there is no need to check it before
calling the function.
4) Simplify ice_vsi_alloc() call. There is no need to check the type of
VSI before calling ice_vsi_alloc(). For ICE_VSI_CHNL vf is always NULL
(ice_vsi_setup() is called with vf=NULL).
For ICE_VSI_VF or ICE_VSI_CTRL ch is always NULL and for other VSI types
ch and vf are always NULL.
5) Remove unnecessary call to ice_vsi_dis_irq(). ice_vsi_dis_irq() will
be called in ice_vsi_close() flow (ice_vsi_close() -> ice_vsi_down() ->
ice_vsi_dis_irq()). Remove unnecessary call.
6) Don't remove specific filters in release. All hw filters are removed
in ice_fltr_remove_alli(), which is always called in VSI release flow.
There is no need to remove only ethertype filters before calling
ice_fltr_remove_all().
7) Rename ice_vsi_clear() to ice_vsi_free(). As ice_vsi_clear() only
free memory allocated in ice_vsi_alloc() rename it to ice_vsi_free()
which better shows what function is doing.
8) Free coalesce param in rebuild. There is potential memory leak if
configuration of VSI lan fails. Free coalesce to avoid it.

BPF kernel <-> kernel API stability has been discussed at length over
the last several weeks and months. Now that we've largely aligned over
kfuncs being the way forward, and BPF helpers being considered
functionally frozen, it's time to document the expectations for kfunc
lifecycles and stability so that everyone (BPF users, kfunc developers,
and maintainers) are all aligned, and have a crystal-clear understanding
of the expectations surrounding kfuncs.
To do that, this patch adds that documentation to the main kfuncs
documentation page via a new 'kfunc lifecycle expectations' section. The
patch describes how decisions are made in the kernel regarding whether
to include, keep, deprecate, or change / remove a kfunc. As described
very overtly in the patch itself, but likely worth highlighting here:
"kfunc stability" does not mean, nor ever will mean, "BPF APIs may block
development elsewhere in the kernel".
Rather, the intention and expectation is for kfuncs to be treated like
EXPORT_SYMBOL_GPL symbols in the kernel. The goal is for kfuncs to be a
safe and valuable option for maintainers and kfunc developers to extend
the kernel, without tying anyone's hands, or imposing any kind of
restrictions on maintainers in the same way that UAPI changes do.
In addition to the 'kfunc lifecycle expectations' section, this patch
also adds documentation for a new KF_DEPRECATED kfunc flag which kfunc
authors or maintainers can choose to add to kfuncs if and when they
decide to deprecate them. Note that as described in the patch itself, a
kfunc need not be deprecated before being changed or removed -- this
flag is simply provided as an available deprecation mechanism for those
that want to provide a deprecation story / timeline to their users.
When necessary, kfuncs may be changed or removed to accommodate changes
elsewhere in the kernel without any deprecation at all.
