Some 1000BASE-T PHY modules take a while for the PHY to wake up. Retry the probe a number of times before deciding that the module has no PHY. Tested with: Sourcephotonics SPGBTXCNFC - PHY takes less than 50ms to respond. Champion One 1000SFPT - PHY takes about 200ms to respond. Mikrotik S-RJ01 - no PHY Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
