-.It Va hw.ixl.enable_msix
-Allows one to enable/disable MSIX, thus forcing MSI instead.
-.It Va hw.ixl.ringsz
-Set the number of descriptors in the rings, note that this
-changes BOTH the TX and RX rings, they cannot be set independently.
-.It Va hw.ixl.max_queues
-Set the number of queues (each a TX/RX pair) for the port, this
-allows one to override the autocalculation if it is set to 0.

-The dynamic RX interrupt control, set to 1 to enable.

+Filter out packets with Ethertype 0x8808 from being sent out by non-adapter
+sources. This prevents (potentially untrusted) software or
+.Xr ixlv 4
+devices from sending out flow control packets.
+Enabled by default.
+.It Va hw.ixl.enable_head_writeback
+When the driver is finding the last TX descriptor processed by the hardware,
+use a value written to memory by the hardware instead of scanning the
+descriptor ring for completed descriptors.
+Enabled by default; disable to mimic the TX behavior found in
