Two different set_mac functions exists but stmmac_dwmac4_set_mac() is
only used for enabling and never for disabling.
So on dwmac4, the MAC RX/TX is never disabled.
This patch add a generic function pointer set_mac() to stmmac_ops and
replace all call to stmmac_set_mac/stmmac_dwmac4_set_mac by a call to
this pointer.
Since dwmac4_ops is const, set_mac cannot be modified after, and so dwmac4_ops
is duplioacted like dwmac4_dma_ops.

The linking status may be changed when autosuspend. And, after
autoresume, the driver may try to transmit packets when the device
is carrier off, because the interrupt transfer doesn't update the
linking status, yet. And, if the device is in ALDPS mode, the device
would stop working.
The another similar case is
1. unplug the cable.
2. interrupt transfer queue a work_queue for linking change.
3. device enters the ALDPS mode.
4. a tx occurs before the work_queue is called.

====================
net: bridge: allow user-space to add ext learned entries
This set adds the ability to add externally learned entries from
user-space. For symmetry and proper function we need to allow SW entries
to take over HW learned ones (similar to how HW can take over SW entries
currently) which is needed for our use case (evpn) where we have pure SW
ports and HW ports mixed in a single bridge. This does not play well with
switchdev devices currently because there's no feedback when the entry is
taken over, but this case has never worked anyway and feedback can be
easily added when needed.
Patch 02 simply allows to use NTF_EXT_LEARNED from user-space, we already
have Quagga patches that make use of this functionality.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The NTF_EXT_LEARNED flag was added for switchdev and externally learned
entries, but it can also be used for entries learned via a software
in user-space which requires dynamic entries that do not expire.
One such case that we have is with quagga and evpn which need dynamic
entries but also require to age them themselves.

WM8960 derives bit clock from sysclock using BCLKDIV[3:0] of R8
clocking register (See WM8960 datasheet, page 71).
There are use cases, like this:
aplay -Dhw:0,0 -r 48000 -c 1 -f S20_3LE -t raw audio48k20b_3LE1c.pcm
where no BCLKDIV applied to sysclock can give us the exact requested
bitclk, so driver fails to configure clocking and aplay fails to run.
Fix this by relaxing bitclk computation, so that when no exact value
can be derived from sysclk pick the closest value greater than
expected bitclk.

One of main purpose of commit 1a653aa447 ("ASoC: core: replace...")
was remove replaceable list (= list_aux) from snd_soc_component by using

Now we allocate one page array for managing resync pages, instead
of using bio's vec table to do that, and the old way is very hacky
and won't work any more if multipage bvec is enabled.
The introduced cost is that we need to allocate (128 + 16) * copies
bytes per r10_bio, and it is fine because the inflight r10_bio for
resync shouldn't be much, as pointed by Shaohua.
Also bio_reset() in raid10_sync_request() and reshape_request()
are removed because all bios are freshly new now in these functions
and not necessary to reset any more.
This patch can be thought as cleanup too.
