As per 802.3bz, if bit 14 of (1.11) "PMA Extended Abilities" indicates whether or not we should read register (1.21) "2.52/5G PMA Extended Abilities", which contains information on the support of 2.5GBASET and 5GBASET. After testing on several variants of PHYS of this family, it appears that bit 14 in (1.11) isn't always set when it should be. PHYs 88X3310 (on MacchiatoBin) and 88E2010 do support 2.5G and 5GBASET, but don't have 1.11.14 set. Their register 1.21 is filled with the correct values, indicating 2.5G and 5G support. PHYs 88E2110 do have their 1.11.14 bit set, as it should. Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

README
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.
