Author: mav Date: Thu Feb 28 21:07:16 2019 New Revision: 344669 URL: https://svnweb.freebsd.org/changeset/base/344669 Log: Limit 24xx adapters to only MSI interrupts by default. This was actually the known good configuration we used before. Single MSI-X configuration doesn't even work there on my tests, just due to lack of documentation not sure whether by design or I am doing something wrong.
