tls: Return type of non-data records retrieved using MSG_PEEK in recvmsg
The patch enables returning 'type' in msghdr for records that are
retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked
from socket from getting clubbed with any other record of different
type when records are subsequently dequeued from strparser.
For each record, we now retain its type in sk_buff's control buffer
cb[]. Inside control buffer, record's full length and offset are already
stored by strparser in 'struct strp_msg'. We store record type after
'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is
stored just after record dequeue. For tls1.3, the type is stored after
record has been decrypted.
Inside process_rx_list(), before processing a non-data record, we check
that we must be able to return back the record type to the user
application. If not, the decrypted records in tls context's rx_list is
left there without consuming any data.

mlxsw: spectrum_acl: Don't take rtnl mutex for region rehash
Jiri says:
During region rehash, a new region is created with a more optimized set
of masks (ERPs). When transitioning to the new region, all the rules
from the old region are copied one-by-one to the new region. This
transition can be time consuming and currently done under RTNL lock.
In order to remove RTNL lock dependency during region rehash, introduce
multiple smaller locks guarding dedicated structures or parts of them.
That is the vast majority of this patchset. Only patch #1 is simple
cleanup and patches 12-15 are improving or introducing new selftests.

net: phy: marvell10g: Add 2.5GBaseT support
This series adds the missing bits necessary to fully support 2.5GBaseT

The main points for that support are :
- Making use of the .get_features call, recently introduced by Heiner
and Andrew, that allows having a fully populated list of supported
modes, including 2500BaseT.
- Configuring the MII to 2500BaseX when establishing a link at 2.5G
- Adding a small quirk to take into account the fact that some PHYs in
the family won't report the correct supported abilities
The rest of the series consists of small cosmetic improvements such as
using the correct helper to set a linkmode bit and adding macros for the
PHY ids.

====================
net: protodown support for macvlan and vxlan
This patch series adds dev_change_proto_down_generic, a generic
implementation of ndo_change_proto_down, which sets the netdev carrier
state according to the new proto_down value.
This handler adds the ability to set protodown on macvlan and vxlan
interfaces in a generic way for use by control protocols like VRRPD.
Patch (1) introduces the handler in net/code/dev.c. Patch (2) and (3) add
support for change_proto_down in macvlan and vxlan drivers, respectively,
using the new function.

Vlad Buslov says:
====================
Add tests for unlocked flower classifier implementation
Implement tests for tdc testsuite to verify concurrent rules update with
rtnl-unlocked flower classifier implementation. The goal of these tests
is to verify general flower classifier correctness by updating filters
on same classifier instance in parallel and to verify its atomicity by
concurrently updating filters in same handle range. All three filter
update operations (add, replace, delete) are tested.
Existing script tdc_batch.py is re-used for batch file generation. It is
extended with several optional CLI arguments that are needed for
concurrency tests. Thin wrapper tdc_multibatch.py is implemented on top
of tdc_batch.py to simplify its usage when generating multiple batch
files for several test configurations.
Parallelism in tests is implemented by running multiple instances of tc
in batch mode with xargs tool. Xargs is chosen for its ease of use and
because it is available by default on most modern Linux distributions.
