Author: ian Date: Sat Oct 28 16:50:23 2017 New Revision: 325054 URL: https://svnweb.freebsd.org/changeset/base/325054 Log: Increase the alignment of the rx/tx descriptor ring buffers to 64 bytes. 16 was the correct alignment for older hardware, but the imx7 requires 64-byte alignment, which is a fine value to use on all systems.
