Author: mw Date: Thu Nov 9 13:33:02 2017 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. Submitted by: Michal Krawczyk <mk@semihalf.com> Reviewed by: byenduri_gmail.com Obtained from: Semihalf Sponsored by: Amazon, Inc.
