New Revision: 344910
URL: https://svnweb.freebsd.org/changeset/base/344910

Log:
  MFC r344661, r344669: 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.
