In this advisory it is said that "No workaround is available, but systems that do not have Intel(R) 82559 series 10Gb Ethernet Controllers are not affected."
I suspect a 82599 controller is the correct entry, because a 82559 is a fast ethernet controller (well, not so fast anymore).

proposed patch - change the Intel chipset number for ixgbe.
Interesting finding. Unless the issue only manifests on the 82599 chipset, I'd say we could try something a little different on a two fold approach: #1 reword the advisory and #2 update the man page with a caveat section.
#1 - Reword of the advisory (patch provided):
Because the patch affects the entire ixgbe(4) driver, to be in conformance with what the man page says, I'd suggest the advisory to read:
No workaround is available, but systems that do not have Intel(R) 82598EB series 10Gb Ethernet Controllers are not affected.
The man page for ixgbe states the following:
The ixgbe driver provides support for PCI 10Gb Ethernet adapters based on
the Intel 82598EB Intel(R) Network Connections. The driver supports
Jumbo Frames, MSIX, TSO, and RSS.
#2 - Caveat section (patch provided):
Since this option is now the default on ixgbe we could add that in a caveat section of the man page for the driver (following examples of others such as ral(4).

proposed patch - add a CAVEAT section to the ixgbe(4) man page.
