Add 1000BASE-KX interface mode. This 1G backplane ethernet as described in
clause 70. Clause 73 autonegotiation is mandatory, and only full duplex
operation is supported.
Although at the PMA level this interface mode is identical to
1000BASE-X, it uses a different form of in-band autonegation. This
justifies a separate interface mode, since the interface mode (along
with the MLO_AN_* autonegotiation mode) sets the type of autonegotiation
which will be used on a link. This results in more than just electrical
differences between the link modes.
With regard to 1000BASE-X, 1000BASE-KX holds a similar position to
SGMII: same signaling, but different autonegotiation. PCS drivers
(which typically handle in-band autonegotiation) may only support
1000BASE-X, and not 1000BASE-KX. Similarly, the phy mode is used to
configure serdes phys with phy_set_mode_ext. Due to the different
electrical standards (SFI or XFI vs Clause 70), they will likely want to
use different configuration. Adding a phy interface mode for
1000BASE-KX helps simplify configuration in these areas.

Signed-off-by: David S. Miller <davem@davemloft.net>
Instead of setting the queue depth once during probe, adjust it on the
fly whenever we configure the link. This is a bit unusal, since usually
the DPAA driver calls into the FMAN driver, but here we do the opposite.
We need to add a netdev to struct mac_device for this, but it will soon
live in the phylink config.
I haven't tested this extensively, but it doesn't seem to break
anything. We could possibly optimize this a bit by keeping track of the
last rate, but for now we just update every time. 10GEC probably doesn't
need to call into this at all, but I've added it for consistency.

We don't need to remap the base address from the resource twice (once in
mac_probe() and again in set_fman_mac_params()). We still need the
resource to get the end address, but we can use a single function call
to get both at once.
While we're at it, use platform_get_mem_or_io and devm_request_resource
to map the resource. I think this is the more "correct" way to do things
here, since we use the pdev resource, instead of creating a new one.
It's still a bit tricky, since we need to ensure that the resource is a

net: dsa: microchip: lan937x: enable interrupt for internal phy link detection
This patch series enables the internal phy link detection for lan937x using the
interrupt method. lan937x acts as the interrupt controller for the internal
ports and phy, the irq_domain is registered for the individual ports and in
turn for the individual port interrupts.
RFC v3 -> Patch v1
- Removed the RFC v3 1/3 from the series - changing exit from reset
- Changed the variable name in ksz_port from irq to pirq
- Added the check for return value of irq_find_mapping during phy irq
registeration.
- Moved the clearing of POR_READY_INT from girq_thread_fn to
lan937x_reset_switch

This patch enables the interrupts for internal phy link detection for
LAN937x. The interrupt enable bits are active low. There is global
interrupt mask for each port. And each port has the individual interrupt
mask for TAS. QCI, SGMII, PTP, PHY and ACL.
The first level of interrupt domain is registered for global port
interrupt and second level of interrupt domain for the individual port
interrupts. The phy interrupt is enabled in the lan937x_mdio_register
function. Interrupt from which port is raised will be detected based on
the interrupt host data.

to find out from which port interrupt has triggered, we need to pass the

get the port from which interrupt triggered, but to identify it is phy
interrupt we have to read status register. The regmap structure for
accessing the device register is present in the ksz_device struct. To
access the ksz_device from the ksz_port, the reference is added to it
with port number as well.

net: ipa: start using transaction IDs
A previous group of patches added ID fields to track the state of
transactions:

This series starts using those IDs instead of the lists used

Signed-off-by: David S. Miller <davem@davemloft.net>
Using a little logic we can simplify gsi_channel_trans_last().
The first condition in that function looks like this:
if (trans_info->allocated_id != trans_info->free_id)
And if that's false, we proceed to the next one:
if (trans_info->committed_id != trans_info->allocated_id)
Failure of the first test implies:
trans_info->allocated_id == trans_info->free_id
And therefore, the second one can be rewritten this way:
if (trans_info->committed_id != trans_info->free_id)
Substituting free_id for allocated_id and committed_id can also be
done in the code blocks executed when these conditions yield true.
The net result is that all three blocks for TX endpoints can be
consolidated into just one.
The two blocks of code at the end of that function (used for both TX
and RX channels) can be similarly consolidated into a single block.

When quiescing a channel, we find the "last" transaction, which is
the latest one to have been allocated. (New transaction allocation
will have been prevented by the time this is called.)
Currently we do this by looking for the first non-empty transaction
list in each state, then return the last entry from that last.
Instead, determine the last entry in each list (if any) and return
that entry if found.
Temporarily (locally) introduce list_last_entry_or_null() as a
helper for this, mirroring list_first_entry_or_null(). This macro
definition will be removed by an upcoming patch.

net: altera: tse: phylink conversion
This is V4 of a series converting the Altera TSE driver to phylink,
introducing a new PCS driver along the way.
The Altera TSE can be built with a SGMII/1000BaseX PCS, allowing to use
SFP ports with this MAC, which is the end goal of adding phylink support
and a proper PCS driver.
The PCS itself can either be mapped in the MAC's register space, in that
case, it's accessed through 32 bits registers, with the higher 16 bits
always 0. Alternatively, it can sit on its own register space, exposing
16 bits registers, some of which ressemble the standard PHY registers.
To tackle that rework, several things needs updating, starting by the DT
binding, since we add support for a new register range for the PCS.
Hence, the first patch of the series is a conversion to YAML of the
existing binding.
Then, patch 2 does a bit of simple cleanup to the TSE driver, using nice
reverse xmas tree definitions.
Patch 3 adds the actual PCS driver, as a standalone driver. Some future
series will then reuse that PCS driver from the dwmac-socfpga driver,
which implements support for this exact PCS too, allowing to share the
code nicely.
Patch 4 is then a phylink conversion of the altera_tse driver, to use
this new PCS driver.
Finally, patch 5 updates the newly converted DT binding to support the
pcs register range.
This series contains bits and pieces for this conversion, please tell me if
you want me to send it as individual patches.
V4 Changes:
- Add missing MODULE_* macros to the TSE PCS driver
V3 Changes:
- YAML binding conversion changes and PCS addition changes thanks to
Krzysztof's reviews
V2 Changes :
- Fixed the binding after the YAML conversion
- Added a pcs_validate() callback
- Introduced a comment to justify a soft reset for the PCS

NULL.
However, we already use mac80211_hwsim_tx_iter() which
deals with all this, so remove the test and adjust the
remaining code a bit.
This then means we no longer use the chanctx pointer,
so remove it as well.

Currently, other paths calling drv_sta_state() hold the mutex
and therefore drivers can assume that, and look at links with
that protection. Fix that for the reconfig path as well; to
do it more easily use ieee80211_reconfig_stations() for the
AP/AP_VLAN station reconfig as well.

Add an MLD address attribute to BSS entries that the interface
is currently associated with to help userspace figure out what's
going on.

Catch the bugs fixed in mac80211 by the previous commits
and warn if an invalid address is added (or removed).
