Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+Fax with isdn4linux
+===================
+
+When enabled during kernel configuration, the tty emulator
+of the ISDN subsystem is capable of the Fax Class 2 commands.
+
+This only makes sense under the following conditions :
+
+- You need the commands as dummy, because you are using
+ hylafax (with patch) for AVM capi.
+- You want to use the fax capabilities of your isdn-card.
+ (supported cards are listed below)
+
+
+NOTE: This implementation does *not* support fax with passive
+ ISDN-cards (known as softfax). The low-level driver of
+ the ISDN-card and/or the card itself must support this.
+
+
+Supported ISDN-Cards
+--------------------
+
+Eicon DIVA Server BRI/PCI
+ - full support with both B-channels.
+
+Eicon DIVA Server 4BRI/PCI
+ - full support with all B-channels.
+
+Eicon DIVA Server PRI/PCI
+ - full support on amount of B-channels
+ depending on DSPs on board.
+
+
+
+The command set is known as Class 2 (not Class 2.0) and
+can be activated by AT+FCLASS=2
+
+
+The interface between the link-level-module and the hardware-level driver
+is described in the files INTERFACE.fax and INTERFACE.
