Setting up macvlan/macvtap networks over atlantic NIC results
in no traffic over these networks because ndo_set_rx_mode did
not listed UC MACs as registered in unicast filter.
Here we fix that taking into account maximum number of UC
filters supported by hardware. If more than MAX addresses were
registered, we just enable promisc and/or allmulti to pass
the traffic in.
We also remove MULTICAST_ADDRESS_MAX constant from aq_cfg since
thats not a configurable parameter at all.

We now pass link drop status to FW on init/deinit. This is required
to inform FW that driver took/released a control on link.
FW then will manage its own state and device power profile based
on this information. To improve management we remove mpi_set
function which ambiguously took both state and speed parameters.
Deinit callback is now a part of FW ops, as it actually manages the FW.

From: Colin Ian King <colin.king@canonical.com>
This was originally mistakenly submitted to net-next. Resubmitting to net.
The comparison of numvecs < 0 is always false because numvecs is a u32
and hence the error return from a failed call to pci_alloc_irq_vectores
is never detected. Fix this by using the signed int ret to handle the
error return and assign numvecs to err.

Driver should use pci_alloc_irq_vectors return value to correct number
of allocated vectors and napi instances. Otherwise it'll panic later
in pci_irq_vector.
Driver also should allow more than one MSI vectors to be allocated.
Error return path from pci_alloc_irq_vectors is also fixed to revert
resources in a correct sequence when error happens.

In case netdev is closed at the moment of pci shutdown, aq_nic_stop
gets called second time. napi_disable in that case hangs indefinitely.
In other case, if device was never opened at all, we get oops because
of null pointer access.
We should invoke aq_nic_stop conditionally, only if device is running
at the moment of shutdown.

On ASUS XG-C100C with 1.5.44 firmware a special mode called "dirty wake"
is active. With this mode when motherboard gets powered (but no poweron
happens yet), NIC automatically enables powersave link and watches
for WOL packet.
This normally allows to powerup the PC after AC power failures.
Not all motherboards or bios settings gives power to PCI slots,
so this mode is not enabled on all the hardware.
4.16 linux driver introduced full hardware reset sequence
This is required since before that we had no NIC hardware
reset implemented and there were side effects of "not clean start".
But this full reset is incompatible with "dirty wake" WOL feature
it keeps the PHY link in a special mode forever. As a consequence,
driver sees no link and no traffic.
To fix this we forcibly change FW state to idle state before doing
the full reset. This makes FW to restore link state.

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e61 (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

We should close link and all NIC operations during shutdown.
On some systems graceful reboot never closes NIC interface on its own,
but only indicates pci device shutdown. Without explicit handler, NIC
rx rings continued to transfer DMA data into prepared buffers while CPU
rebooted already. That caused memory corruptions on soft reboot.

We should report to napi full budget only when we have more job to do.
Before this fix, on any tx queue cleanup we forced napi to do poll again.
Thats a waste of cpu resources and caused storming with napi polls when
there was at least one tx on each interrupt.
With this fix we report full budget only when there is more job on TX
to do. Or, as before, when rx budget was fully consumed.
