            Bug ID: 194197
           Summary: IGB cards need a kernel option to enable legacy mode
                    (to support ALTQ)

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.
