Since in qdisc_create, the destroy op is called when init fails, we
don't do cleanup in init and leave it up to destroy.

====================
net: sched: Make qdisc offload uapi uniform
Several qdiscs can already be offloaded to hardware, but there's an
inconsistecy in regard to the uapi through which they indicate such
an offload is taking place - indication is passed to the user via
TCA_OPTIONS where each qdisc retains private logic for setting it.
The recent addition of offloading to RED in
602f3baf2218 ("net_sch: red: Add offload ability to RED qdisc") caused
the addition of yet another uapi field for this purpose -
TC_RED_OFFLOADED.
For clarity and prevention of bloat in the uapi we want to eliminate
said added uapi, replacing it with a common mechanism that can be used
to reflect offload status of the various qdiscs.
The first patch introduces TCA_HW_OFFLOAD as the generic message meant
for this purpose. The second changes the current RED implementation into
setting the internal bits necessary for passing it, and the third removes
TC_RED_OFFLOADED as its no longer needed.

Following the previous patch, RED is now using the new uniform uapi
for indicating it's offloaded. As a result, TC_RED_OFFLOADED is no
longer utilized by kernel and can be removed [as it's still not
part of any stable release].

Let RED utilize the new internal flag, TCQ_F_OFFLOADED,

Qdiscs can be offloaded to HW, but current implementation isn't uniform.
Instead, qdiscs either pass information about offload status via their
TCA_OPTIONS or omit it altogether.
Introduce a new attribute - TCA_HW_OFFLOAD that would form a uniform
uAPI for the offloading status of qdiscs.

net: aquantia: Atlantic driver 12/2017 updates
The patchset contains important hardware fix for machines with large MRRS
and couple of improvement in stats and capabilities reporting
patch v3:
- Fixed patch #7 after Andrew's finding. NIC level stats actually
have to be cleaned only on hw struct creation (and this is done
in kzalloc). On each hwinit we only have to reset link state
to make sure hw stats update will not increment nic stats during init.
patch v2:
- split into more detailed commits

On very first start we should read out current HW counter values

This also should be done each time NIC gets down/up or wakes up

When a PHY has the BMCR_PDOWN bit set, it may decide to ignore writes
to other registers, or reset the registers to power-on defaults.
Micrel PHYs do this for their interrupt registers.
The current structure of phylib tries to enable interrupts before
resuming (and releasing) the BMCR_PDOWN bit. This fails, causing
Micrel PHYs to stop working after a suspend/resume sequence if they
are using interrupts.
Fix this by ensuring that the PHY driver resume methods do not take
the phydev->lock mutex themselves, but the callers of phy_resume()
take that lock. This then allows us to move the call to phy_resume()
before we enable interrupts in phy_start().
