Hello,
In our embedded designs, this is a useful patch. Maybe it can be useful
for somebody else too.
Or maybe there are already better solutions?
I know I could also write a driver for our switch, but that is too much
effort just to select the active port.
Kind regards,
Jürgen
In embedded design, instead of a PHY, sometimes a switch is used that
behaves as a PHY through its MII port. For example to use a daisy
chain network configuration instead of an expensive star config.
In that case, many phy ports are available, but only 1 should
be used
to check link status, and not the first one available as is
the case
without this configuration (that is, set to its default value 0).
So this options specifies the switch port number to be used
to check
link status, because if the link is down, no data is sent by the
TCP/IP stack.

This is not going to work well with all switches out there. You could use the
fixed-PHY driver to make your ethernet driver see the link as always up between
the MAC and switch CPU port.
A better solution would be to have proper switch drivers and user-space, which
reminds me that we (OpenWrt) should at some point propose our switch drivers
[1] for review.

Do not all switches follow the basic MII register map with room for 31

Indeed, I tried to, but it didn't work. (would be my preferred solution)
I juist enabled FIXED_PHY in menuconfig (and kept MII, NET_ETHERNET and
FEC (for my iMX cpu); also PHYLIB is on that makes mdio_bus.c compile).
I checked the architecture file for mpc866ads and didn't find any init
for it, but maybe I need to initialize fixed-PHY somewhere?
However, it could be interesting sometimes from application side to know
if the real external link is up, then fixed-PHY is not ok.

Just had a fast look to the Marvell switch driver. Nice to know it is there.

This config option may help your platform but it is nowhere reusable on a
slightly different one (each mii_bus behavior is changed).
Which driver(s) do you use that you can not set phy_mask directly ?

The HW driver is 'FEC' for iMX Ethernet. For the PHY, just MII and PHYLIB.
I am rather new to linux, didn't knew phy_mask. Checked it now, and is
not set in fec.c.
You mean then to patch drivers/net/fec.c in the same way (as my current
patch) to set the phy_mask instead (via menuconfig, or in the platform
init)?

It is not my area but I would have drivers/net/fec.c::fec_devtype.driver_data
point to a real struct where the relevant phy_mask and the current quirks
are stored, then add a new entry in fec_devtype and a reference to it
(Kconfig + platform init) somewhere below arch/arm/plat-mxc.
Freescale's application note suggests that the MX25 fec allows some freedom
for the implementation of the media interface. So it may not be overkill.

It is not my area but I would have drivers/net/fec.c::fec_devtype.driver_data
point to a real struct where the relevant phy_mask and the current quirks
are stored, then add a new entry in fec_devtype and a reference to it
(Kconfig + platform init) somewhere below arch/arm/plat-mxc.
Freescale's application note suggests that the MX25 fec allows some freedom
for the implementation of the media interface. So it may not be overkill.
