e1000e sets different WoL settings in system suspend callback and
runtime suspend callback.
The suspend direct complete optimization leaves e1000e in runtime
suspended state with wrong WoL setting during system suspend.
To fix this, we need to disable suspend direct complete optimization to
let e1000e always use suspend callback to set correct WoL during system
suspend.

It is normal user behaviour to start, stop, then start a stream
again without closing it. Currently this works for compressed
playback streams but not capture ones.
The states on a compressed capture stream go directly from OPEN to
PREPARED, unlike a playback stream which moves to SETUP and waits
for a write of data before moving to PREPARED. Currently however,
when a stop is sent the state is set to SETUP for both types of
streams. This leaves a capture stream in the situation where a new
start can't be sent as that requires the state to be PREPARED and
a new set_params can't be sent as that requires the state to be
OPEN. The only option being to close the stream, and then reopen.
Correct this issues by allowing snd_compr_drain_notify to set the
state depending on the stream direction, as we already do in
set_params.

The match level computed by the driver gets to be wrong for decap
rules with wildcarded inner packet match such as:

enc_dst_ip 192.168.0.9 enc_key_id 100 enc_dst_port 4789
action tunnel_key unset
action mirred egress redirect dev eth1
The FW errs for a missing matching meta-data indicator for the outer
headers (where we do have a match), and a wrong matching meta-data
indicator for the inner headers (where we don't have a match).
Fix that by taking into account the matching on the tunnel info and
relating the match level of the encapsulated packet to the firmware
inner headers indicator in case of decap.
As for vxlan we mandate a match on the tunnel udp dst port, and in general
we practically madndate a match on the source or dest ip for any IP tunnel,
the fix was done in a minimal manner around the tunnel match parsing code.

Sven Auhagen reports that if he changes a SFP+ module for a SFP module
on the Macchiatobin Single Shot, the link does not come back up. For
Sven, it is as easy as:
- Insert a SFP+ module connected, and use ping6 to verify link is up.
- Remove SFP+ module
- Insert SFP 1000base-X module use ping6 to verify link is up: Link
up event did not trigger and the link is down
but that doesn't show the problem for me. Locally, this has been
reproduced by:
- Boot with no modules.
- Insert SFP+ module, confirm link is up.
- Replace module with 25000base-X module. Confirm link is up.
- Set remote end down, link is reported as dropped at both ends.
- Set remote end up, link is reported up at remote end, but not local
end due to lack of link interrupt.
Fix this by setting up both GMAC and XLG interrupts for port 0, but
only unmasking the appropriate interrupt according to the current mode
set in the mac_config() method. However, only do the mask/unmask
dance when we are really changing the link mode to avoid missing any
link interrupts.

involving BPF_PROG_TYPE_TRACEPOINT, BPF_PROG_TYPE_PERF_EVENT,

====================
This patch series adds BTF deduplication algorithm to libbpf. This algorithm
allows to take BTF type information containing duplicate per-compilation unit
information and reduce it to equivalent set of BTF types with no duplication without
loss of information. It also deduplicates strings and removes those strings that
are not referenced from any BTF type (and line information in .BTF.ext section,
if any).
Algorithm also resolves struct/union forward declarations into concrete BTF types
across multiple compilation units to facilitate better deduplication ratio. If
undesired, this resolution can be disabled through specifying corresponding options.
When applied to BTF data emitted by pahole's DWARF->BTF converter, it reduces
the overall size of .BTF section by about 65x, from about 112MB to 1.75MB, leaving
only 29247 out of initial 3073497 BTF type descriptors.
Algorithm with minor differences and preliminary results before FUNC/FUNC_PROTO

When I moved the refcount to refcount_t type I missed the fact that
refcount_inc() will result in use-after-free warning with
CONFIG_REFCOUNT_FULL=y builds.
The correct fix would be to init the reference count to 1 at allocation
time, but, unfortunately we cannot do this, as we can't undo that
in case something else fails later in the batch.
So only solution I see is to special-case the 'new entry' condition
and replace refcount_inc() with a "delayed" refcount_set(1) in this case,
as done here.
The .activate callback can be removed to simplify things, we only
need to make sure that deactivate() decrements/unlinks the entry
from the list at end of transaction phase (commit or abort).

for the loopback address because it used rt6_need_strict().
REDIRECT rules in the OUTPUT chain rewrite the destination to loopback
address; thus its oif should not be preserved. This commit fixes the bug
that redirected local packets are being dropped. Actually the packet was
not exactly dropped; Instead it was sent out to the original oif rather
than lo. When a packet with daddr ::1 is sent to the router, it is
effectively dropped.

With the recent print rework we now have the following problem:

libbpf_print does va_start and calls __libbpf_pr with va_list argument.
In __base_pr we again do va_start. Because the next argument is a

Fix this by changing libbpf_print_fn_t signature to accept va_list and

represented by a connection with all of its independent resources
like that of a normal connection, and is differentiated by
service type. In other words, there can be multiple qp connections
between an IP pair and each supports a unique service type.
The feature has been added from RDSv4.1 onwards and supports
rolling upgrades. RDMA connection metadata also carries the tos
information to set up SL on end to end context. The original
code was developed by Bang Nguyen in downstream kernel back in
2.6.32 kernel days and it has evolved over period of time.

RDMA transport maps user tos to underline virtual lanes(VL)
for IB or DSCP values. RDMA CM transport abstract thats for
RDS. TCP transport makes use of default priority 0 and maps
all user tos values to it.

RDS Service type (TOS) is user-defined and needs to be configured
via RDS IOCTL interface. It must be set before initiating any
traffic and once set the TOS can not be changed. All out-going
traffic from the socket will be associated with its TOS.

For legacy protocol version incompatibility with non linux RDS,
consumer reject reason being used to convey it to peer. But the
choice of reject reason value as '1' was really poor.
Anyway for interoperability reasons with shipping products,
it needs to be supported. For any future versions, properly
encoded reject reason should to be used.

Mark RDSv3.1 as compat version and add v4.1 version macro's.
Subsequent patches enable TOS(Type of Service) feature which is
tied with v4.1 for RDMA transport.

sh_eth: implement simple RX checksum offload
Here's a set of 7 patches against DaveM's 'net-next.git' repo. I'm implemeting
the simple RX checksum offload (like was done for the 'ravb' driver by Simon
Horman); it has been only tested on the R8A7740 and R8A77980 SoCs, the other
SoCs should just work (according to their manuals)...
