Author: sobomax Date: Wed May 22 04:51:08 2019 New Revision: 348091 URL: https://svnweb.freebsd.org/changeset/base/348091
Log: Make aacraid(4) working on ASR8805 & ASR8402 in particular. This patch has been in the PR system for 5 months and then on reviews for another 5. Nobody came with any cases where it fails, while many people cried for it to be commited & merged.
