Subject: [taroon patch] Add docs detailing which drivers support netconsole
Tracking: 0982.jmoyer.netconsole-drvrs-doc.patch
Archives: 2005-May/msg00359.html
Status: committed in -32.5.EL



Currently, our support staff tell customers that they can determine which
adapters support netconsole by doing the following:

  "A simple way to check what drivers have this capability is to install
   the kernel-source package and search the source code in
   /usr/src/kernel-<version> for the definition HAVE_POLL_CONTROLLER."

This is so incredibly poor it hurts.  Here is a patch that will add the
supported driver list to the Documentation/networking directory, which in
turn gets put into the kernel-doc package.

Please ACK.

+The netconsole module provides 3 pieces of functionality:
+    1) generation of syslog messages which are delivered to a remote syslog
+       server
+    2) generation of netconsole messages which are delivered to a remote
+       netdump server
+    3) a network kernel crash dump facility
+The configuration for the module is specified in the /etc/sysconfig/netdump
+file, which is self-documented.  Once the parameters are specified in that
+provided you have installed the netdump rpm.
+Network drivers must implement a special hook in order to work with
+netconsole.  The following drivers implement this functionality, and thus
+can be used in conjunction with netconsole:
