We have logic to determine the desired promisc mode in _each_ code path.
Change things around so that there is a clean split between
(a) high-level code that selects the new mode, and (b) implementations
of the various mechanisms to program this mode.
This also keeps qeth_promisc_to_bridge() from polluting the debug logs

Except for card->read_cmd, every cmd we issue now passes through
qeth_send_control_data() and allocates a qeth_reply struct. The way we
use this struct requires additional refcounting, and pointer tracking.
Clean up things by moving most of qeth_reply's content into the main
cmd struct. This keeps things in one place, saves us the additional
refcounting and simplifies the overall code flow.
A nice little benefit is that we can now match incoming replies against
the pending requests themselves, without caching the requests' seqnos.
The qeth_reply struct stays around for a little bit longer in a shrunk
form, to avoid touching every single callback.

net: dsa: enable and disable all ports
The DSA stack currently calls the .port_enable and .port_disable switch
callbacks for slave ports only. However, it is useful to call them for all
port types. For example this allows some drivers to delay the optimization
of power consumption after the switch is setup. This can also help reducing
the setup code of drivers a bit.
The first DSA core patches enable and disable all ports of a switch, regardless
their type. The last mv88e6xxx patches remove redundant code from the driver
setup and the said callbacks, now that they handle SERDES power for all ports.
Changes in v2: do not guard .port_disable for broadcom switches.

simply guard all implementations against non user ports and return

Note that bcm_sf2_sw_suspend() currently calls bcm_sf2_port_disable()

The netns sctp feature flags shouldn't work as a global switch,
which is mostly like a firewall/netfilter's job. Also, it will

Since each type of chunk's processing function will check the

removed, and net sctp.x_enable will only work as the default
feature flags for the future sctp sockets/endpoints.

The maximum key description size is 4095. Commit f771fde820 ("keys:
Simplify key description management") inadvertantly reduced that to 255
and made sizes between 256 and 4095 work weirdly, and any size whereby
size & 255 == 0 would cause an assertion in __key_link_begin() at the
following line:
BUG_ON(index_key->desc_len == 0);
This can be fixed by simply increasing the size of desc_len in struct
keyring_index_key to a u16.
Note the argument length test in keyutils only checked empty
descriptions and descriptions with a size around the limit (ie. 4095)
and not for all the values in between, so it missed this. This has been

Add compatible for the ethernet IP core on MT7628/88 SoCs. Its
compatible with the older Ralink Rt5350F SoC. And OpenWrt already
uses this compatible string for the MT76x8.

Adaptive coalescing is managed per adapter not per event queue so it
does not needed to store 'enable' flag for each event queue.

====================
flow_offload hardware priority fixes
This patchset contains two updates for the flow_offload users:
1) Pass the major tc priority to drivers so they do not have to
lshift it. This is a preparation patch for the fix coming in
patch #2.
2) Set the hardware priority from the netfilter basechain priority,
some drivers break when using the existing hardware priority
number that is set to zero.
v5: fix patch 2/2 to address a clang warning and to simplify
the priority mapping.

This patch adds initial support for offloading basechains using the
priority range from 1 to 65535. This is restricting the netfilter
priority range to 16-bit integer since this is what most drivers assume
so far from tc. It should be possible to extend this range of supported
priorities later on once drivers are updated to support for 32-bit
integer priorities.

tc transparently maps the software priority number to hardware. Update
it to pass the major priority which is what most drivers expect. Update
drivers too so they do not need to lshift the priority field of the
flow_cls_common_offload object. The stmmac driver is an exception, since
this code assumes the tc software priority is fine, therefore, lshift it
just to be conservative.

In i2400m_barker_db_init(), 'options_orig' is allocated through kstrdup()
to hold the original command line options. Then, the options are parsed.
However, if an error occurs during the parsing process, 'options_orig' is
not deallocated, leading to a memory leak bug. To fix this issue, free
'options_orig' before returning the error.
