SJA1105 switches R and S have one SerDes port with an 802.3z
quasi-compatible PCS, hardwired on port 4. The other ports are still
MII/RMII/RGMII. The PCS performs rate adaptation to lower link speeds;
the MAC on this port is hardwired at gigabit. Only full duplex is
supported.
The SGMII port can be configured as part of the static config tables, as
well as through a dedicated SPI address region for its pseudo-clause-22
registers. However it looks like the static configuration is not
able to change some out-of-reset values (like the value of MII_BMCR), so
at the end of the day, having code for it is utterly pointless. We are
just going to use the pseudo-C22 interface.
Because the PCS gets reset when the switch resets, we have to add even
more restoration logic to sja1105_static_config_reload, otherwise the
SGMII port breaks after operations such as enabling PTP timestamping
which require a switch reset.
>From PHYLINK perspective, the switch supports *only* SGMII (it doesn't
support 1000Base-X). It also doesn't expose access to the raw config
word for in-band AN in registers MII_ADV/MII_LPA.
It is able to work in the following modes:
- Forced speed
- SGMII in-band AN slave (speed received from PHY)
- SGMII in-band AN master (acting as a PHY)
The latter mode is not supported by this patch. It is even unclear to me
how that would be described. There is some code for it left in the
patch, but 'an_master' is always passed as false.

This patch adds support for configuring the RGMII skew delays in Rx and
Tx. The Rx and Tx skews are set based on the interface mode. By default
their configuration is set to the default value in hardware (0.2ns);
this means the driver do not rely anymore on the bootloader
configuration.
Then based on the interface mode being used, a 2ns delay is added:
- RGMII_ID adds it for both Rx and Tx.
- RGMII_RXID adds it for Rx.
- RGMII_TXID adds it for Tx.

Commit a5afc16780 ("net: phy: mscc: add support for VSC8584 PHY")
introduced a call to 'phy_write' storing its return value to a variable
called 'ret'. But 'ret' never was checked for a possible error being
returned, and hence was not used at all. Fix this by checking the return
value and exiting the function if an error was returned.
As this does not fix a known bug, this commit is mostly cosmetic and not

Chelsio NICs have 3 filter regions, in following order of priority:
1. High Priority (HPFILTER) region (Highest Priority).
2. HASH region.
3. Normal FILTER region (Lowest Priority).
Currently, there's a 1-to-1 mapping between the prio value passed
by TC and the filter region index. However, it's possible to have
multiple TC rules with the same prio value. In this case, if a region
is exhausted, no attempt is made to try inserting the rule in the
next available region.
So, rework and remove the 1-to-1 mapping. Instead, dynamically select
the region to insert the filter rule, as long as the new rule's prio
value doesn't conflict with existing rules across all the 3 regions.

did_interrupt() clears the interrupt, therefore handle_interrupt() can
not check which event triggered the interrupt. To overcome this
constraint and allow more flexibility for customer interrupt handlers,
let's decouple handle_interrupt() from parts of the phylib interrupt
handling. Custom interrupt handlers now have to implement the
did_interrupt() functionality in handle_interrupt() if needed.
Fortunately we have just one custom interrupt handler so far (in the
mscc PHY driver), convert it to the changed API.
