The limit for BQL is updated each time we call
netdev_tx_completed_queue.
Without this patch the BQL limit was updated for every TX event we
see.
The issue was that this only updated the limit to handle the data
we complete in two events as the first event wouldn't show that
enough traffic had been processed between them.
This was OK when interrupt moderation was off but not when it was
on as more data had to be completed in a single interrupt.
The patch changes this so that we do report the completion to BQL
only when all the TX events in the interrupt have been processed.

As its first order of business, boomerang_interrupt() checks whether
the device really has any pending interrupts. If it does not,
it does nothing and returns, but it still returns IRQ_HANDLED.
This is wrong: interrupt was not handled, IRQ handlers of other
devices sharing this IRQ line need to be called.
vortex_interrupt() has it right: it returns IRQ_NONE in this case
via IRQ_RETVAL(0).
Do the same in boomerang_interrupt().

vmxnet3's current napi path is built to count every rx descriptor we recieve,
and use that as a count of the napi budget. That means its possible to return
from a napi poll halfway through recieving a fragmented packet accross multiple
dma descriptors. If that happens, the next napi poll will start with the
descriptor ring in an improper state (e.g. the first descriptor we look at may
have the end-of-packet bit set), which will cause a BUG halt in the driver.
Fix the issue by only counting whole received packets in the napi poll and
returning that value, rather than the descriptor count.

Since commit b0e9a30dd6 ("bridge: Add vlan id to multicast groups")
there's a check in br_ip_equal() for a matching vlan id, but the mdb
functions were not modified to use (or at least zero it) so when an
entry was added it would have a garbage vlan id (from the local br_ip
variable in __br_mdb_add/del) and this would prevent it from being
matched and also deleted. So zero out the whole local ip var to protect
ourselves from future changes and also to fix the current bug, since
there's no vlan id support in the mdb uapi - use always vlan id 0.
Example before patch:
root@debian:~# bridge mdb add dev br0 port eth1 grp 239.0.0.1 permanent
root@debian:~# bridge mdb
dev br0 port eth1 grp 239.0.0.1 permanent
root@debian:~# bridge mdb del dev br0 port eth1 grp 239.0.0.1 permanent
RTNETLINK answers: Invalid argument

Some versions of MCFW do not support the MC_CMD_VADAPTOR_SET_MAC
command, and ENOSYS will be returned.
If the PF created its own vport, the function's datapath must be
stopped and the vport can be reconfigured to reflect the new MAC
address.
If the MCFW created the vport for the PF (which is the case when
the nic_data->vport_mac is blank), nothing further needs to be
done as the vport is not under the control of the PF.
This only applies to PFs because the MCFW in question does not
support VFs.

Jason Gunthorpe reported that since commit c02db8c629 ("rtnetlink: make
SR-IOV VF interface symmetric"), we don't verify IFLA_VF_INFO attributes
anymore with respect to their policy, that is, ifla_vfinfo_policy[].
Before, they were part of ifla_policy[], but they have been nested since
placed under IFLA_VFINFO_LIST, that contains the attribute IFLA_VF_INFO,
which is another nested attribute for the actual VF attributes such as
IFLA_VF_MAC, IFLA_VF_VLAN, etc.
Despite the policy being split out from ifla_policy[] in this commit,
it's never applied anywhere. nla_for_each_nested() only does basic nla_ok()
testing for struct nlattr, but it doesn't know about the data context and
their requirements.
Fix, on top of Jason's initial work, does 1) parsing of the attributes
with the right policy, and 2) using the resulting parsed attribute table
from 1) instead of the nla_for_each_nested() loop (just like we used to
do when still part of ifla_policy[]).

If rhashtable_walk_next detects a resize operation in progress, it jumps
to the new table and continues walking that one. But it misses to drop
the reference to it's current item, leading it to continue traversing
the new table's bucket in which the current item is sorted into, and
after reaching that bucket's end continues traversing the new table's
second bucket instead of the first one, thereby potentially missing
items.
This fixes the rhashtable runtime test for me. Bug probably introduced
by Herbert Xu's patch eddee5ba ("rhashtable: Fix walker behaviour during

On UML builds, mdio-mux-mmioreg.c fails to compile:
drivers/net/phy/mdio-mux-mmioreg.c:50:3: error: implicit declaration of function ‘ioremap’ [-Werror=implicit-function-declaration]
drivers/net/phy/mdio-mux-mmioreg.c:63:3: error: implicit declaration of function ‘iounmap’ [-Werror=implicit-function-declaration]
This is due to CONFIG_OF now being user selectable. Add a dependency on
HAS_IOMEM to fix this.
