net: phylink: avoid reducing support mask

2019-06-04T18:43:24+00:00

Avoid reducing the support mask as a result of the interface type
selected for SFP modules, or when setting the link settings through
ethtool - this should only change when the supported link modes of
the hardware combination change.

net: sfp: read eeprom in maximum 16 byte increments

2019-06-03T22:16:37+00:00

Some SFP modules do not like reads longer than 16 bytes, so read the
EEPROM in chunks of 16 bytes at a time.  This behaviour is not specified
in the SFP MSAs, which specifies:

 "The serial interface uses the 2-wire serial CMOS E2PROM protocol
  defined for the ATMEL AT24C01A/02/04 family of components."

and

 "As long as the SFP+ receives an acknowledge, it shall serially clock
  out sequential data words. The sequence is terminated when the host
  responds with a NACK and a STOP instead of an acknowledge."

We must avoid breaking a read across a 16-bit quantity in the diagnostic
page, thankfully all 16-bit quantities in that page are naturally
aligned.

net: phy: dp83867: Set up RGMII TX delay

2019-05-29T21:28:48+00:00

PHY_INTERFACE_MODE_RGMII_RXID is less then TXID
so code to set tx delay is never called.

net: phy: dp83867: increase SGMII autoneg timer duration

2019-05-29T21:28:48+00:00

After reset SGMII Autoneg timer is set to 2us (bits 6 and 5 are 01).
That is not enough to finalize autonegatiation on some devices.
Increase this timer duration to maximum supported 16ms.

net: phy: dp83867: fix speed 10 in sgmii mode

2019-05-29T21:28:48+00:00

For supporting 10Mps speed in SGMII mode DP83867_10M_SGMII_RATE_ADAPT bit
of DP83867_10M_SGMII_CFG register has to be cleared by software.
That does not affect speeds 100 and 1000 so can be done on init.

net: phy: marvell10g: report if the PHY fails to boot firmware

2019-05-29T21:25:10+00:00

Some boards do not have the PHY firmware programmed in the 3310's flash,
which leads to the PHY not working as expected.  Warn the user when the
PHY fails to boot the firmware and refuse to initialise.

net: phylink: ensure consistent phy interface mode

2019-05-29T21:20:24+00:00

Ensure that we supply the same phy interface mode to mac_link_down() as
we did for the corresponding mac_link_up() call.  This ensures that MAC
drivers that use the phy interface mode in these methods can depend on
mac_link_down() always corresponding to a mac_link_up() call for the
same interface mode.

Do not update the link interface mode while the link is down to avoid
spurious link interface changes.

Always call mac_config if we have a PHY to propagate the pause mode
settings to the MAC.
