Currently if the VF adds a VLAN, VLAN pruning will be enabled for that VSI.
Also, when a VLAN gets deleted it will disable VLAN pruning even if other
VLAN(s) exists for the VF. Fix this by only disabling VLAN pruning on the
VF VSI when removing the last VF (i.e. vf->num_vlan == 0).

Remove code that enables DCB in initialization when SW LLDP is
activated. DCB flag is set or reset before in ice_init_pf_dcb
based on number of TCs. So there is not need to overwrite it.

Setting DCB without checking number of TCs can cause communication
problems with other cards. Host card sends packet with VLAN priority
tag, but client card doesn't strip this tag and ping doesn't work.

====================
mvpp2: per-cpu buffers

This patchset workarounds an PP2 HW limitation which prevents to use
per-cpu rx buffers.
The first patch is just a refactor to prepare for the second one.
The second one allocates percpu buffers if the following conditions are met:
- CPU number is less or equal 4
- no port is using jumbo frames

If the following conditions are not met at load time, of jumbo frame is enabled
later on, the shared allocation is reverted.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Every mvpp2 unit can use up to 8 buffers mapped by the BM (the HW buffer
manager). The HW will place the frames in the buffer pool depending on the
frame size: short (< 128 bytes), long (< 1664) or jumbo (up to 9856).

As any unit can have up to 4 ports, the driver allocates only 2 pools,
one for small and one long frames, and share them between ports.
When the first port MTU is set higher than 1664 bytes, a third pool is
allocated for jumbo frames.

This shared allocation makes impossible to use percpu allocators,
and creates contention between HW queues.

If possible, i.e. if the number of possible CPU are less than 8 and jumbo
frames are not used, switch to a new scheme: allocate 8 per-cpu pools for
short and long frames and bind every pool to an RXQ.

When the first port MTU is set higher than 1664 bytes, the allocation
scheme is reverted to the old behaviour (3 shared pools), and when all
ports MTU are lowered, the per-cpu buffers are allocated again.

devlink_free is complaining right here:

	WARN_ON(!list_empty(&devlink->port_list));

This happens because devlink_port_unregister is no longer done right
away in dsa_port_setup when a DSA_PORT_TYPE_USER has failed.
Vivien said about this change that:

    Also no need to call devlink_port_unregister from within dsa_port_setup
    as this step is inconditionally handled by dsa_port_teardown on error.

which is not really true. The devlink_port_unregister function _is_
being called unconditionally from within dsa_port_setup, but not for
this port that just failed, just for the previous ones which were set
up.

ports_teardown:
	for (i = 0; i < port; i++)
		dsa_port_teardown(&ds->ports[i]);

Initially I was tempted to fix this by extending the "for" loop to also
cover the port that failed during setup. But this could have potentially
unforeseen consequences unrelated to devlink_port or even other types of
ports than user ports, which I can't really test for. For example, if
for some reason devlink_port_register itself would fail, then
unconditionally unregistering it in dsa_port_teardown would not be a
smart idea. The list might go on.

So just make dsa_port_setup undo the setup it had done upon failure, and
let the for loop undo the work of setting up the previous ports, which
are guaranteed to be brought up to a consistent state.

net: dsa: mv88e6xxx: centralize SERDES IRQ handling

Following Marek's work on the abstraction of the SERDES lanes mapping, this
series trades the .serdes_irq_setup and .serdes_irq_free callbacks for new
.serdes_irq_mapping, .serdes_irq_enable and .serdes_irq_status operations.

This has the benefit to limit the various SERDES implementations to simple
register accesses only; centralize the IRQ handling and mutex locking logic;
as well as reducing boilerplate in the driver.

Pointer reg_info is being initialized with a value that is never read and
is being re-assigned a little later on. The assignment is redundant
and hence can be removed.

In commit 99cd149e ("sgiseeq: replace use of dma_cache_wback_inv"),
a call to 'get_zeroed_page()' has been turned into a call to
'dma_alloc_coherent()'. Only the remove function has been updated to turn
the corresponding 'free_page()' into 'dma_free_attrs()'.
The error hndling path of the probe function has not been updated.

Fix it now.

Rename the corresponding label to something more in line.
