Description Jan Jurkus 2015-08-25 23:16:58 UTC
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."
https://www.freebsd.org/security/advisories/FreeBSD-EN-15:14.ixgbe.asc

I suspect a 82599 controller is the correct entry, because a 82559 is a fast ethernet controller (well, not so fast anymore).

Comment 2 Diego Casati 2017-01-18 00:38:17 UTC

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:

DESCRIPTION                                                                   
     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).
