https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194197 Bug ID: 194197 Summary: IGB cards need a kernel option to enable legacy mode (to support ALTQ) Product: Base System Version: 10.1-BETA3 Hardware: Any OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: dan_256@yahoo.com Created attachment 148039 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=148039&action=edit Adds IGB_LEGACY_TX and IXGBE_LEGACY_TX to kernel options IGB cards still do not support ALTQ, except in "legacy" mode, since FreeBSD 7/8. To enable legacy mode, patching of the kernel source is required. There is no official documentation on how to patch source, although reading between the lines on various forums would point you in the right direction. I created the attached patch to enable legacy mode in IGB driver through a kernel option, rather than a patch. A similar patch needs to be created for IXGBE. Because of bug https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193053, IXGBE will not compile with the kernel option set, but IGB will. Still, there should be a way to enable this option for IXGBE, even if it does not currently compile. -- You are receiving this mail because: You are the assignee for the bug.
