40GbE Intel Wired LAN Driver Updates 2016-06-27
This series contains updates to i40e and i40evf only.
Mitch provides several changes, first adds functions to enable and disable
VSI on a VEB, which allows for configuration of limited promiscuous mode
specifically for bridging purposes. Sets the RSS Hash Enable registers by
default now that VF RSS is configured by the PF driver. Fixed a issue
where we could overflow the buffer, by checking the address count and bail
out of the loop at the appropriate time. Removed the need for a reset
when the device enters limited promiscuous mode, since this was causing
heartburn for people who were using VFs and bridging.
Catherine adds a call to set the client interface down when we put the VSI
down. Fixed an issue where RSS queues was being limited to the number
of CPUs, so if a user wants to use more queues than CPUs, we want to
trust they know what they are doing and let them.
Greg cleans up the driver suspend routine to ensure we are calling
synchronize_irq() before freeing IRQ vectors and explicitly free the other
causes interrupt resources and shut down the MSIX interrupt.
Serey fixes i40e_set_settings() to not fail when a Direct Attach (DA)
cable is used.
Avinash fixes a supported link bug by removing code which was not allowing
100BaseT to show up in the supported link modes for 10GBaseT PHYs.
Shannon adds a bit of information to the error messages to help determine
the source of error by adding VSI info to macaddr messages.
Tushar Dave fixes error received when turning off TSO on some systems,
which was caused by enabling FD_SB without checking availability of
MSIx vectors, so add the check.
Neerav fixes a possible panic when LLDP/DCBX change happens and the
driver tried to notify the client(s) for each of the PF VSIs, which would
panic when it reached a VSI that did not have any netdev associated with
it.

it with 55e7f6abe1 ("dsa: b53: fix big-endian register access"),
however it now came back in a different randconfig build that happens
to have different inlining decisions in the compiler.
The mistake that gcc makes here is that it thinks the second call to
readl() might fail because the address 'reg + 4' is not a multiple
of four despite having knowing that 'reg' itself is a multiple of four.
By open-coding the two reads without the redundant alignment check,
we can avoid the warning and produce slightly better object code, but
get slightly longer source code instead.

drivers: net: cpsw: improve runtime pm
This series intended to improve runtime PM and allow CPSW to be
RPM suspended when all ethX netdevices are down.
To achieve above goal it is required to relax runtime PM constraints for
Davinci MDIO which blocks CPSW runtime PM now, because Davinci MDIO is always
powered on during probe and powered off only when it's going to be removed.
- Patches 6-11 implement PM runtime autosuspend for Davinci MDIO, but keep it
disabled by default, because Davinci MDIO is integrated in big set of TI devices
and not all of them verified to work correctly with RPM autosuspend enabled:
expected to work on SoCs where MDIO is defined as part of CPSW in DT
(cpsw.c DRA7/am57x, am437x, am335x)
The CPSW need to be fixed before RPM suspended can be allowed:
- Patches 1-5 ensure that CPSW will not cause L3 errors while it is in RPM
suspended state.
Davinci MDIO RPM autosuspend can be enabled through sysfs:
echo 100 > /sys/devices/../48484000.ethernet/48485000.mdio/power/autosuspend_delay_ms
Patches 12 - 15: introduce new compatible string "ti,cpsw-mdio" which is used
then to enable RPM for am335x/am437x/dra7 SoCs.
Tested on am335x, am437x, am572x and k2g (on k2g with RPM disabled for Davinci MDIO)
These changes should not affect on errata i877 implementation on DRA7.
Power measurement on am335x GP EVM:
Without this series: 547.60 mW total SoC power
With this series + "ifconfig eth0 down": 477.32 mW Total Soc Power
Changes in v2:
- CPSW ethtool interface updated to use .begin()/.complete() callbacks
- kbuild failure fixed
- davinci_mdio DT updated with proper description of allowed compatible strings
combinations

Davinci MDIO is always used as slave device which services
read/write requests from MDIO/PHY core. It doesn't use IRQ also.
As result, It's possible to relax PM runtime constraints for Davinci
MDIO and enable it on demand, instead of powering it during probe
and powering off during removal.
Hence, implement PM runtime autosuspend for Davinci MDIO, but keep it
disabled by default, because Davinci MDIO is integrated in big set of
TI devices and not all of them expected to work corectly with RPM
autosuspend enabled:
- expected to work on SoCs where MDIO is part of TI CPSW

- not verified on Keystone 2 and other SoCs where MDIO is used with TI EMAC IP

functioning if System enters suspend when all ethX net-devices are

cpsw_suspend() will try to call soft_reset_slave() unconditionally

stmmac: rework and enhance the PCS support
The 3.xx and 4.xx synopsys gmacs have a very similar
PCS embedded module and they share almost the same registers;
for example:
AN_Control, AN_Status, AN_Advertisement, AN_Link_Partner_Ability,
AN_Expansion, TBI_Extended_Status.
Just the RGMII/SMII Control/Status register differs.
So these patches aim to reorganize and enhance the PCS support;
to do that, some small inline functions have been provided and
also some rework to the PCS ISR part has been done.
In the end, the SGMII for MAC2MAC connection has been introduced.
