I've replaced the offending memcpy with ether_addr_copy, because I'm
100% sure, that of_get_mac_address can't return NULL as it returns valid
pointer or ERR_PTR encoded value, nothing else.
I'm hesitant to just change IS_ERR into IS_ERR_OR_NULL check, as this
would make the warning disappear also, but it would be confusing to
check for impossible return value just to make a compiler happy.
I'm now changing all occurencies of memcpy to ether_addr_copy after the
of_get_mac_address call, as it's very likely, that we're going to get
similar reports from kbuild test robot in the future.

NFP shift instruction has something special. If shift direction is left
then shift amount of 1 to 31 is specified as 32 minus the amount to shift.
But no need to do this for indirect shift which has shift amount be 0. Even
after we do this subtraction, shift amount 0 will be turned into 32 which
will eventually be encoded the same as 0 because only low 5 bits are
encoded, but shift amount be 32 will fail the FIELD_PREP check done later
on shift mask (0x1f), due to 32 is out of mask range. Such error has been
observed when compiling nfp/bpf/jit.c using gcc 8.3 + O3.
This issue has started when indirect shift support added after which the
incoming shift amount to __emit_shf could be 0, therefore it is at that
time shift amount adjustment inside __emit_shf should have been tightened.

NFP does not register devlink ports for representors (without
the "devlink: expose PF and VF representors as ports" series
there are no port flavours to expose them as).
Commit c25f08ac65 ("nfp: remove ndo_get_port_parent_id implementation")
went to far in removing ndo_get_port_parent_id for representors.
This causes redirection offloads to fail, and switch_id attribute
missing.
Reintroduce the ndo_get_port_parent_id callback for representor ports.

Current order in open:
-> Enable interrupts (macb_init_hw)
-> Enable NAPI
-> Start PHY
Sequence of RX handling:
-> RX interrupt occurs
-> Interrupt is cleared and interrupt bits disabled in handler
-> NAPI is scheduled
-> In NAPI, RX budget is processed and RX interrupts are re-enabled
With the above, on QEMU or fixed link setups (where PHY state doesn't
matter), there's a chance macb RX interrupt occurs before NAPI is
enabled. This will result in NAPI being scheduled before it is enabled.
Fix this macb open by changing the order.

When desc filling fails in hns3_nic_net_xmit, it will call
hns3_clear_desc to unmap the dma mapping. But currently the
ring->next_to_use points to the desc where the desc filling
or dma mapping return error, which means the desc that
ring->next_to_use points to has not done the dma mapping,
the desc that need unmapping is before the ring->next_to_use.
This patch fixes it by calling ring_ptr_move_bw(next_to_use)
before doing unmapping operation, and set desc_cb->dma to
zero to avoid freeing it again when unloading.
Also, when filling skb head or frag fails, both need to unmap
all the way back to next_to_use_head, so remove one desc filling
error handling.

100GbE Intel Wired LAN Driver Updates 2019-05-04
This series contains updates to the ice driver only.
Jesse updated the driver to make more functions consistent in their use
of a local variable for vsi->back. Updates the driver to use bit fields
when possible to avoid wasting lots of storage space to store single bit
values. Optimized the driver to be more memory efficient by moving
structure members around that are not in are hot path.
Michal updates the driver to disable the VF if malicious device driver
(MDD) event is detected by the hardware. Adds checks to validate the
messages coming from the VF driver. Tightens up the sniffing of the
driver so that transmit traffic so that VF's cannot see what is on other
VSIs.
Tony fixed the driver so that receive stripping state won't change every
time transmit insertion is changed. Cleanup the __always_unused
attribute, now that the variable is being used. Fixed the function
which evaluates setting of features to ensure that can evaluate and set
multiple features in a single function call.
Akeem fixes the driver so that we do not attempt to remove a VLAN filter
that does not exist. Adds support for adding a ethertype based filter
rule on VSI and describe it in a very long run-on sentence. :-)
Bruce cleans up static analysis warnings by removing a local variable
initialization that is not needed.
Brett makes the allocate/deallocate more consistent in all the driver
flows for VSI q_vectors. In addition, makes setting/getting coalesce
settings more consistent throughout the driver.

40GbE Intel Wired LAN Driver Updates 2019-05-04
This series contains updates to i40e only.
Grzegorz fixes a bug with promiscuous mode not being kept when the VF
switched to a new VLAN. Fixed a typo in the link mode code, by using
the correct define. Fixed truncation issue, which changed an function
argument to a smaller value that should have been a larger value.
Aleksandr adds support for new x710 devices and the speeds they support.
Sergey adds a check for the number of vectors against the number of MSIx
vectors to ensure one does not exceed the other.
Martyna adds additional input validation on VF messages handled by the
PF. Fixed potential memory leaks in the driver where the error paths
were not freeing allocated memory.
Maciej reverts the double ShadowRAM checksum calculation change because
issues were found in the NVM downgrade situation.
Gustavo Silva changes the i40e driver to use struct_size() in kzalloc()
calls, to avoid type mistakes.

When testing I figured out that most operations signal finish even
before we trigger the first delay. Seems like PCI(e) access and
memory barriers typically add enough latency. Therefore move the
first delay after the first check.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable size is not necessary, hence it
is removed.
This code was detected with the help of Coccinelle.

The driver was converted to not use bool, but it was
neglected that the bools should have been converted to bit fields
as bit fields in software structures are ok, as long as they
use the correct kinds of unsigned types. This avoids
wasting lots of storage space to store single bit values.
One of the change hunks moves a variable lport out of
a group of "combinable" bit fields because all bits of
the u8 lport are valid and the variable can be packed in the
struct in struct holes.
