Subject: Define netdev_features_t
This was done in upstream commit
c8f44affb7244f2ac3e703cab13d55ede27621bb, but we just want the type
definition for use by backported drivers rather than changing
everything to use it.

Subject: filter: Allow to create sk-unattached filters
commit 302d663740cfaf2c364df6bb61cd339014ed714c upstream.
Today, BPF filters are bind to sockets. Since BPF machine becomes handy
for other purposes, this patch allows to create unattached filter.

commit 61dc3461b9549bc10a2f16d254250680cadafcce upstream.
No need to have spinlock for this purpose. So convert this to mutex and
avoid current schedule while atomic problems in netlink code.

Subject: [04/23] team: replicate options on register
commit 358b838291f618278080bbed435b755f9b46748e upstream.
Since multiple team instances are putting defined options into their
option list, during register each option must be cloned before added
into list. This resolves uncool memory corruptions when using multiple
teams.

commit 2cfa5a0471fef43fda0b7bd87e3a5e4dbadb7809 upstream.
rcu_assign_pointer(ptr, NULL) can be safely replaced by
RCU_INIT_POINTER(ptr, NULL)
(old rcu_assign_pointer() macro was testing the NULL value and could
omit the smp_wmb(), but this had to be removed because of compiler
warnings)

commit 57459185a19b0246866479522b77cbb9732201d1 upstream.
So far when vlan id was added to team device befor port was added, this
vid was not added to port's vlan filter. Also after removal, vid stayed
in port device's vlan filter. Benefit of new vlan functions to handle
this work.

commit b82b9183d4f18f9b8c4bb31f223eb6c79b734eb0 upstream.
This patch changes event message behaviour to send only updated records
instead of whole list. This fixes bug on which userspace receives non-actual
data in case multiple events occur in row.

Subject: [13/23] team: Stop using NLA_PUT*().
commit 86ebb02dc793058ea17ad647c802b507dafff7cb upstream.
These macros contain a hidden goto, and are thus extremely error
prone and make code hard to audit.

Subject: [16/23] team: add support for per-port options
commit 80f7c6683fe0e891ef1db7c967d538b5fdddd22c upstream.
This patch allows to create per-port options. That becomes handy for all
sorts of stuff, for example for userspace driven link-state, 802.3ad
implementation and so on.

Subject: [17/23] team: add bool option type
commit 14f066bab19946545130a7379f420af860a02ae8 upstream.
Add another (hopefully last) option type. Use NLA_FLAG to implement
that.

Subject: [18/23] team: add user_linkup and user_linkup_enabled per-port
option
commit 71472ec12c61dd305ab4d11822af7ecc4f9717f9 upstream.
Allows userspace to setup linkup for ports. Default is to take linkup
directly from ethtool state.

Subject: [22/23] team: allow to enable/disable ports
commit 19a0b58e506b06fd41659d8734bba6a3e87980f4 upstream.
This patch changes content of hashlist (used to get port struct by
computed index (0...en_port_count-1)). Now the hash list contains only
enabled ports so userspace will be able to say what ports can be used
for tx/rx. This becomes handy when userspace will need to disable ports
which does not belong to active aggregator. By default, newly added port
is enabled.
