net: phy: mscc: fix macsec key length

2021-07-14T15:07:19+00:00

[ Upstream commit c309217f91f2d2097c2a0a832d9bff50b88c81dc ]

The key length used to store the macsec key was set to MACSEC_KEYID_LEN
(16), which is an issue as:
- This was never meant to be the key length.
- The key length can be > 16.

Fix this by using MACSEC_MAX_KEY_LEN instead (the max length accepted in
uAPI).

net: phy: dp83867: perform soft reset and retain established link

2021-06-11T17:13:03+00:00

Current logic is performing hard reset and causing the programmed
registers to be wiped out.

as per datasheet: https://www.ti.com/lit/ds/symlink/dp83867cr.pdf
8.6.26 Control Register (CTRL)

do SW_RESTART to perform a reset not including the registers,
If performed when link is already present,
it will drop the link and trigger re-auto negotiation.

net: mdiobus: get rid of a BUG_ON()

2021-05-17T22:50:58+00:00

We spotted a bug recently during a review where a driver was
unregistering a bus that wasn't registered, which would trigger this
BUG_ON().  Let's handle that situation more gracefully, and just print
a warning and return.

net: phy: marvell: enable downshift by default

2021-04-30T22:20:47+00:00

A number of PHYs support the PHY tunable to set and get
downshift. However, only 88E1116R enables downshift by default. Extend
this default enabled to all the PHYs that support the downshift
tunable.

net: phy: marvell: add downshift support for M88E1240

2021-04-28T20:58:11+00:00

Add downshift support for 88E1240, it uses the same downshift
configuration registers as 88E1011.

phy: nxp-c45-tja11xx: add interrupt support

2021-04-23T21:13:16+00:00

Added .config_intr and .handle_interrupt callbacks.

Link event interrupt will trigger an interrupt every time when the link
goes up or down.

net: phy: marvell: fix m88e1111_set_downshift

2021-04-22T20:20:39+00:00

Changing downshift params without software reset has no effect,
so call genphy_soft_reset() after change downshift params.

As the datasheet says:
Changes to these bits are disruptive to the normal operation therefore,
any changes to these registers must be followed by software reset
to take effect.
