This patch changes the way we handle the maximum frame size for the Rx path. Previously we were rounding up to 2K for a 1500 MTU and then brining the max frame size down to MTU plus a fixed amount. With this patch applied what we now do is limit the maximum frame to 1.5K minus the value for NET_IP_ALIGN for standard MTU, and for any MTU greater than 1500 we allow up to the maximum frame size. This makes the behavior more consistent with the other drivers such as igb which had similar logic. In addition it reduces the test matrix for MTU since we only have two max frame sizes that are handled for Rx now.

README
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.
