dsa_slave_prechangeupper_sanity_check() is supposed to enforce some
adjacency restrictions, and calls ds->ops->port_prechangeupper if the
driver implements it.
We convert the error code from the port_prechangeupper() call to a
notifier code, and 0 is converted to NOTIFY_OK, but the caller of
dsa_slave_prechangeupper_sanity_check() stops at any notifier code
different from NOTIFY_DONE.
Avoid this by converting back the notifier code to an error code, so
that both NOTIFY_OK and NOTIFY_DONE will be seen as 0. This allows more
parallel sanity check functions to be added.

Traditionally, DSA has had a single netdev notifier handling function
for each device type.
For the sake of code cleanliness, we would like to introduce more
handling functions which do one thing, but the conditions for entering
these functions start to overlap. Example: a handling function which
tracks whether any bridges contain both DSA and non-DSA interfaces.
Either this is placed before dsa_slave_changeupper(), case in which it
will prevent that function from executing, or we place it after
dsa_slave_changeupper(), case in which we will prevent it from
executing. The other alternative is to ignore errors from the new
handling function (not ideal).
To support this usage, we need to change the pattern. In the new model,
we enter all notifier handling sub-functions, and exit with NOTIFY_DONE
if there is nothing to do. This allows the sub-functions to be
relatively free-form and independent from each other.

====================
vsock: updates for SO_RCVLOWAT handling
This patchset includes some updates for SO_RCVLOWAT:
1) af_vsock:
During my experiments with zerocopy receive, i found, that in some
cases, poll() implementation violates POSIX: when socket has non-
default SO_RCVLOWAT(e.g. not 1), poll() will always set POLLIN and
POLLRDNORM bits in 'revents' even number of bytes available to read
on socket is smaller than SO_RCVLOWAT value. In this case,user sees
POLLIN flag and then tries to read data(for example using 'read()'
call), but read call will be blocked, because SO_RCVLOWAT logic is
supported in dequeue loop in af_vsock.c. But the same time, POSIX
requires that:
"POLLIN Data other than high-priority data may be read without
blocking.
POLLRDNORM Normal data may be read without blocking."
See https://www.open-std.org/jtc1/sc22/open/n4217.pdf, page 293.
So, we have, that poll() syscall returns POLLIN, but read call will
be blocked.
Also in man page socket(7) i found that:
"Since Linux 2.6.28, select(2), poll(2), and epoll(7) indicate a
socket as readable only if at least SO_RCVLOWAT bytes are available."
I checked TCP callback for poll()(net/ipv4/tcp.c, tcp_poll()), it
uses SO_RCVLOWAT value to set POLLIN bit, also i've tested TCP with
this case for TCP socket, it works as POSIX required.
I've added some fixes to af_vsock.c and virtio_transport_common.c,
test is also implemented.
2) virtio/vsock:
It adds some optimization to wake ups, when new data arrived. Now,
SO_RCVLOWAT is considered before wake up sleepers who wait new data.
There is no sense, to kick waiter, when number of available bytes
in socket's queue < SO_RCVLOWAT, because if we wake up reader in
this case, it will wait for SO_RCVLOWAT data anyway during dequeue,
or in poll() case, POLLIN/POLLRDNORM bits won't be set, so such
exit from poll() will be "spurious". This logic is also used in TCP
sockets.
3) vmci/vsock:
Same as 2), but i'm not sure about this changes. Will be very good,
to get comments from someone who knows this code.
4) Hyper-V:
As Dexuan Cui mentioned, for Hyper-V transport it is difficult to
support SO_RCVLOWAT, so he suggested to disable this feature for
Hyper-V.

Passing 1 as the target to notify_poll_in(), we don't honor
what the user has set via SO_RCVLOWAT, going to set POLLIN
and POLLRDNORM, even if we don't have the amount of bytes
expected by the user.
Let's use sock_rcvlowat() to get the right target to pass to

The ft_offloads table serves to steer packets, which are from the
eswitch, to the representor associated with the packets' source vport.
Previously, if a packet's source vport or metadata was not associated
with any representor, it was forwarded to the uplink representor. The
representor got packets it shouldn't have as they weren't coming from
the uplink vport.
One such effect of this breakage can be observed if the uplink
representor is attached to a bridge, where such illegal packets will
be broadcast to the remaining ports, flooding the switch with illegal
packets. In the case where IB loopback (e.g, SNAP) is enabled, all
transmitted packets would be looped back, and received by the uplink
representor, and result in an infinite feedback loop.
Therefore, block this hole by adding a default drop rule to the
ft_offloads table, so that all unmatched packets with no associated
representor are dropped.

This is caused by the global variable ad_ticks_per_sec being zero as
demonstrated by the reproducer script discussed below. This causes
all timer values in __ad_timer_to_ticks to be zero, resulting
in the periodic timer to never fire.

puts bonding into a state where it never transmits LACPDUs.

For some MAC drivers, they set the mac_managed_pm to true in its
->ndo_open() callback. So before the mac_managed_pm is set to true,
we still want to leverage the mdio_bus_phy_suspend()/resume() for
the phy device suspend and resume. In this case, the phy device is
in PHY_READY, and we shouldn't warn about this. It also seems that
the check of mac_managed_pm in WARN_ON is redundant since we already
check this in the entry of mdio_bus_phy_resume(), so drop it.

In ipa_smem_init(), a Qualcomm SMEM region is allocated (if needed)
and then its virtual address is fetched using qcom_smem_get(). The
physical address associated with that region is also fetched.
The physical address is adjusted so that it is page-aligned, and an
attempt is made to update the size of the region to compensate for
any non-zero adjustment.
But that adjustment isn't done properly. The physical address is
aligned twice, and as a result the size is never actually adjusted.
Fix this by *not* aligning the "addr" local variable, and instead
