William Tu d350a82302 net: erspan: create erspan metadata uapi header
The patch adds a new uapi header file, erspan.h, and moves
the 'struct erspan_metadata' from internal erspan.h to it.

William Tu c69de58ba8 net: erspan: use bitfield instead of mask and offset
Originally the erspan fields are defined as a group into a __be16 field,
and use mask and offset to access each field.  This is more costly due to
calling ntohs/htons.  The patch changes it to use bitfields.

David S. Miller b89d06ce58 Merge branch 'use-tc_cls_can_offload_and_chain0-throughout-the-drivers'
Jakub Kicinski says:

====================
use tc_cls_can_offload_and_chain0() throughout the drivers

This set makes all drivers use a new tc_cls_can_offload_and_chain0()
helper which will set extack in case TC hw offload flag is disabled.

I chose to keep the new helper which also looks at the chain but
renamed it more appropriately.  The rationale being that most drivers
don't accept chains other than 0 and since we have to pass extack
to the helper we can as well pass the entire struct tc_cls_common_offload
and perform the most common checks.

This code makes the assumption that type_data in the callback can
be interpreted as struct tc_cls_common_offload, i.e. the real offload
structure has common part as the first member.  This allows us to
make the check once for all classifier types if driver supports
more than one.

v1:
 - drop the type validation in nfp and netdevsim.
v2:
 - reorder checks in patch 1;
 - split other changes from patch 1;
 - add the i40e patch in;
 - add one more test case - for chain 0 extack.

Jakub Kicinski 2fb89a38d3 selftests/bpf: check for spurious extacks from the driver
Drivers should not report errors when offload is not forced.
Check stdout and stderr for familiar messages when with no
skip flags and with skip_hw.  Check for add, replace, and
destroy.

Jakub Kicinski 878db9f0f2 pkt_cls: add new tc cls helper to check offload flag and chain index
Very few (mlxsw) upstream drivers seem to allow offload of chains
other than 0.  Save driver developers typing and add a helper for
checking both if ethtool's TC offload flag is on and if chain is 0.
This helper will set the extack appropriately in both error cases.

David Ahern 955ec4cb3b net/ipv6: Do not allow route add with a device that is down
IPv6 allows routes to be installed when the device is not up (admin up).
Worse, it does not mark it as LINKDOWN. IPv4 does not allow it and really
there is no reason for IPv6 to allow it, so check the flags and deny if
device is admin down.

Ursula Braun 5ac92a00aa net/smc: handle state SMC_PEERFINCLOSEWAIT correctly
A state transition from closing state SMC_PEERFINCLOSEWAIT to closing
state SMC_APPFINCLOSEWAIT is not allowed. Once a closing indication
from the peer has been received, the socket reaches state SMC_CLOSED.

And receiving a peer_conn_abort just changes the state of the socket
into one of the states SMC_PROCESSABORT or SMC_CLOSED;
sending a peer_conn_abort occurs in smc_close_active() for state
SMC_PROCESSABORT only.
