We have been requiring the supported_interfaces bitmap to be filled in
by MAC drivers that have a mac_select_pcs() method. Now that all MAC
drivers fill in the supported_interfaces bitmap, it is time to enforce
this. We have already required supported_interfaces to be set in order
for optical SFPs to be configured in commit f81fa96d8a6c ("net: phylink:
use phy_interface_t bitmaps for optical modules").
Refuse phylink creation if supported_interfaces is empty, and remove
code to deal with cases where this mask is empty.

Add support for the Fiberstore SFP-10G-T and Walsun HXSX-ATRC-1
modules. Internally, the PCB silkscreen has what seems to be a part
number of WT_502. Fiberstore use v2.2 whereas Walsun use v2.6.
These modules contain a Marvell AQrate AQR113C PHY, accessible through
I2C 0x51 using the "rollball" protocol. In both cases, the PHY is
programmed to use 10GBASE-R with pause-mode rate adaption.
Unlike the other rollball modules, these only need a four second delay
before we can talk to the PHY.

====================
ice: allow matching on meta data
Michal Swiatkowski says:
This patchset is intended to improve the usability of the switchdev
slow path. Without matching on a meta data values slow path works
based on VF's MAC addresses. It causes a problem when the VF wants
to use more than one MAC address (e.g. when it is in trusted mode).
Parse all meta data in the same place where protocol type fields are
parsed. Add description for the currently implemented meta data. It is
important to note that depending on DDP not all described meta data can
be available. Using not available meta data leads to error returned by
function which is looking for correct words in profiles read from DDP.
There is also one small improvement, remove of rx field in rule info
structure (patch 2). It is redundant.

There are several places which open code comparing PHY IDs. Provide a
couple of helpers to assist with this, using a slightly simpler test
than the original:
- phy_id_compare() compares two arbitary PHY IDs and a mask of the
significant bits in the ID.
- phydev_id_compare() compares the bound phydev with the specified
PHY ID, using the bound driver's mask.

The use of a source MAC to direct packets from the VF to the corresponding
port representor is only ok if there is only one MAC on a VF. To support
this functionality when the number of MACs on a VF is greater, it is
necessary to match a source VSI instead of a source MAC.
Let's use the new switch API that allows matching on metadata.
If MAC isn't used in match criteria there is no need to handle adding
rule after virtchnl command. Instead add new rule while port representor
is being configured.
Remove rule_added field, checking for sp_rule can be used instead.
Remove also checking for switchdev running in deleting rule as it can be
called from unroll context when running flag isn't set. Checking for
sp_rule covers both context (with and without running flag).
Rules are added in eswitch configuration flow, so there is no need to
have replay function.

Add meta data matching criteria in the same place as protocol matching
criteria. There is no need to add meta data as special words after
parsing all lookups. Trade meta data in the same why as other lookups.
The one difference between meta data lookups and protocol lookups is
that meta data doesn't impact how the packets looks like. Because of that
ignore it when filling testing packet.
Match on tunnel type meta data always if tunnel type is different than
TNL_LAST.

Information about the direction is currently stored in sw_act.flag.
There is no need to duplicate it in another field.
Setting direction flag doesn't mean that there is a match criteria for
direction in rule. It is only a information for HW from where switch id
should be collected (VSI or port). In current implementation of advance
rule handling, without matching for direction meta data, we can always
set one the same flag and everything will work the same.
Ability to match on direction meta data will be added in follow up
patches.

Add description for each meta data. Redefine tunnel mask to match only
tunneled MAC and tunneled VLAN. It shouldn't try to match other flags
(previously it was 0xff, it is redundant).
VLAN mask was 0xd000, change it to 0xf000. 4 last bits are flags
depending on the same field in packets (VLAN tag). Because of that,
It isn't harmful to match also on ITAG.

Russell King says:
====================
net: sfp: add support for control of rate selection
This series introduces control of the rate selection SFP pins (or
their soft state in the I2C diagnostics EEPROM). Several SNIA documents
(referenced in the commits) describe the various different modes for
these, and we implement them all for maximum compatibility, but as
we know, SFP modules tend to do their own thing, so that may not be
sufficient.
In order to implement this, we need to change the locking arrangement
in the SFP layer - we need to make st_mutex (state mutex) able to be
taken from within the rtnl lock and sm_mutex (state machine mutex).
Essentially, st_mutex protects the hard (gpio) and soft state signals.
So, patches 2 through 5 rejig the locking so that st_mutex is only
ever taken when we want to fiddle with the signal state variables,
read or write the GPIOs, or read or write the soft state.
Patch 1 adds a helper that makes the locking rejig a little easier
as it combines the update of sfp->state with setting the updated
control state to the module.
Patch 6 adds code to phylink to give the signalling rate for various
PHY interface modes that are relevant to SFPs - this is the baud rate
of the encoded signal, not the data rate, which is what matters for
SFPs. This rate is passed through the SFP bus layer into the SFP
socket driver, which initially has a stub sfp_set_signal_rate().
Patch 7 adds the code to the SFP socket driver to parse the rate
selection data in the EEPROM, configure which RS signals need to be
driven, and the signalling rate threshold. We fill in
sfp_set_signal_rate() to set the rate select pins as appropriate.

There are a couple of locations in the code where we modify
sfp->state, and then call sfp_set_state(, sfp->state) to update
the outputs/soft state to control the module. Provide a helper
which takes a mask and new state so that this is encapsulated in
one location.

Florian Westphal says:
====================
Netfilter updates for net-next
nftables updates:
1. Allow key existence checks with maps.
At the moment the kernel requires userspace to pass a destination
register for the associated value, make this optional so userspace
can query if the key exists, just like with normal sets.
2. nftables maintains a counter per set that holds the number of
elements. This counter gets decremented on element removal,
but its only incremented if the set has a upper maximum value.
Increment unconditionally, this will allow us to update the
maximum value later on.
3. At DCCP option maching, from Jeremy Sowden.
4. use struct_size macro, from Christophe JAILLET.
Conntrack:
5. Squash holes in struct nf_conntrack_expect, also Christophe JAILLET.
6. Allow clash resolution for GRE Protocol to avoid a packet drop,
from Faicker Mo.
Flowtable:
Simplify route logic and split large functions into smaller
chunks, from Pablo Neira Ayuso.
