It seems I missed that most ethnl_parse_header_dev_get() callers
declare an on-stack struct ethnl_req_info, and that they simply call
dev_put(req_info.dev) when about to return.

Add an infrastructure to help parsing tc actions in a generic way.
Supporting an action parser means implementing struct mlx5e_tc_act
for that action.
The infrastructure will give the possibility to be generic when parsing tc
actions, i.e. parse_tc_nic_actions() and parse_tc_fdb_actions().
To parse tc actions a user needs to allocate a parse_state instance
and pass it when iterating over the tc actions parsers.
If a parser doesn't exists then a user can treat it as unsupported.
To add an action parser a user needs to implement two callbacks.
The can_offload() callback to quickly check if an action can be offloaded.
The parse_action() callback to do actual parsing and prepare for offload.
Add implementation for drop, trap, mark and accept action parsers with this
commit to act as examples and implement usage of the new infrastructure for
those actions.

Before this change, final state of the DDP pkg load process was
dependent on many variables such as: ice_status, pkg version,
ice_aq_err. The last one had be stored in hw->pkg_dwnld_status.
It was impossible to conclude this state just from ice_status, that's
why logging process of DDP pkg load in the caller was a little bit
complicated.
With this patch new status enum is introduced - ice_ddp_state.
It covers all the possible final states of the loading process.
What's tricky for ice_ddp_state is that not only
ICE_DDP_PKG_SUCCESS(=0) means that load was successful. Actually
three states mean that:
- ICE_DDP_PKG_SUCCESS
- ICE_DDP_PKG_SAME_VERSION_ALREADY_LOADED
- ICE_DDP_PKG_COMPATIBLE_ALREADY_LOADED
ice_is_init_pkg_successful can tell that information.
One ddp_state should not be used outside of ice_init_pkg which is
ICE_DDP_PKG_ALREADY_LOADED. It is more generic, it is used in
ice_dwnld_cfg_bufs to see if pkg is already loaded. At this point
we can't use one of the specific one (SAME_VERSION, COMPATIBLE,
NOT_SUPPORTED) because we don't have information on the package
currently loaded in HW (we are before calling ice_get_pkg_info).
We can get rid of hw->pkg_dwnld_status because we are immediately
mapping aq errors to ice_ddp_state in ice_dwnld_cfg_bufs.
Other errors like ICE_ERR_NO_MEMORY, ICE_ERR_PARAM are mapped the
generic ICE_DDP_PKG_ERR.

DSA tagger-owned storage fixups
It seems that the DSA tagger-owned storage changes were insufficiently
tested and do not work in all cases. Specifically, the NXP Bluebox 3
(arch/arm64/boot/dts/freescale/fsl-lx2160a-bluebox3.dts) got broken by
these changes, because
(a) I forgot that DSA_TAG_PROTO_SJA1110 exists and differs from
DSA_TAG_PROTO_SJA1105
(b) the Bluebox 3 uses a DSA switch tree with 2 switches, and the
tagger-owned storage patches don't cover that use case well, it
seems
Therefore, I'm sorry to say that there needs to be an API fixup: tagging
protocol drivers will from now on connect to individual switches from a
tree, rather than to the tree as a whole. This is more robust against
various ordering constraints in the DSA probe and teardown paths, and is
also symmetrical with the connection API exposed to the switch drivers
themselves, which is also per switch.
With these changes, the Bluebox 3 also works fine.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
On the NXP Bluebox 3 board which uses a multi-switch setup with sja1105,
the mechanism through which the tagger connects to the switch tree is
broken, due to improper DSA code design. At the time when tag_ops->connect()
is called in dsa_port_parse_cpu(), DSA hasn't finished "touching" all
the ports, so it doesn't know how large the tree is and how many ports
it has. It has just seen the first CPU port by this time. As a result,
this function will call the tagger's ->connect method too early, and the
tagger will connect only to the first switch from the tree.
This could be perhaps addressed a bit more simply by just moving the
tag_ops->connect(dst) call a bit later (for example in dsa_tree_setup),
but there is already a design inconsistency at present: on the switch
side, the notification is on a per-switch basis, but on the tagger side,
it is on a per-tree basis. Furthermore, the persistent storage itself is
per switch (ds->tagger_data). And the tagger connect and disconnect
procedures (at least the ones that exist currently) could see a fair bit
of simplification if they didn't have to iterate through the switches of
a tree.
To fix the issue, this change transforms tag_ops->connect(dst) into
tag_ops->connect(ds) and moves it somewhere where we already iterate
over all switches of a tree. That is in dsa_switch_setup_tag_protocol(),
which is a good placement because we already have there the connection
call to the switch side of things.
As for the dsa_tree_bind_tag_proto() method (called from the code path
that changes the tag protocol), things are a bit more complicated
because we receive the tree as argument, yet when we unwind on errors,
it would be nice to not call tag_ops->disconnect(ds) where we didn't
previously call tag_ops->connect(ds). We didn't have this problem before
because the tag_ops connection operations passed the entire dst before,
and this is more fine grained now. To solve the error rewind case using
the new API, we have to create yet one more cross-chip notifier for
disconnection, and stay connected with the old tag protocol to all the
switches in the tree until we've succeeded to connect with the new one
as well. So if something fails half way, the whole tree is still
connected to the old tagger. But there may still be leaks if the tagger
fails to connect to the 2nd out of 3 switches in a tree: somebody needs
to tell the tagger to disconnect from the first switch. Nothing comes
for free, and this was previously handled privately by the tagging
protocol driver before, but now we need to emit a disconnect cross-chip
notifier for that, because DSA has to take care of the unwind path. We
assume that the tagging protocol has connected to a switch if it has set
ds->tagger_data to something, otherwise we avoid calling its
disconnection method in the error rewind path.
The rest of the changes are in the tagging protocol drivers, and have to
do with the replacement of dst with ds. The iteration is removed and the
error unwind path is simplified, as mentioned above.
