In the current driver, the MTU is set to the maximum value capable for the backing device. This decision turned out to be a mistake as it led to confusion among users. The expected initial MTU value used for other IBM vNIC capable operating systems is 1500, with the maximum value (9000) reserved for when Jumbo frames are enabled. This patch sets the MTU to the default value for a net device. It also corrects a discrepancy between MTU values received from firmware, which includes the ethernet header length, and net device MTU values. Finally, it removes redundant min/max MTU assignments after device initialization. Signed-off-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
