New Revision: 325590
URL: https://svnweb.freebsd.org/changeset/base/325590

Log:
  Fix calculating io queues number in ENA driver
  
  The maximum number of io_cq was the same number as maximum io_sq
  indicated by the device working in normal mode (without LLQ).
  It is not always true, especially when LLQ is being enabled.
  Fix it.
