It was been observed that with a particular order of initialisation, the netdev can be up, but the SFP module still has its TX_DISABLE signal asserted. This occurs when the network device brought up before the SFP kernel module has been inserted by userspace. This occurs because sfp-bus layer does not hear about the change in network device state, and so assumes that it is still down. Set netdev->sfp when the upstream is registered to work around this problem. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> 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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
