This chips supports two ways to configure max MTU size: - by setting SW_LEGAL_PACKET_DISABLE bit: if this bit is 0 allowed packed size will be between 64 and bytes 1518. If this bit is 1, it will accept packets up to 2000 bytes. - by setting SW_JUMBO_PACKET bit. If this bit is set, the chip will ignore SW_LEGAL_PACKET_DISABLE value and use REG_SW_MTU__2 register to configure MTU size. Current driver has disabled SW_JUMBO_PACKET bit and activates SW_LEGAL_PACKET_DISABLE. So the switch will pass all packets up to 2000 without any way to configure it. By providing port_change_mtu we are switch to SW_JUMBO_PACKET way and will be able to configure MTU up to ~9000.

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.
