Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+/*
+ * DLCI/FRAD Definitions for Frame Relay Access Devices. DLCI devices are
+ * created for each DLCI associated with a FRAD. The FRAD driver
+ * is not truly a network device, but the lower level device
+ * handler. This allows other FRAD manufacturers to use the DLCI
+ * code, including its RFC1490 encapsulation alongside the current
+ * implementation for the Sangoma cards.
+ *
+ * Version: @(#)if_ifrad.h 0.15 31 Mar 96
+ *
+ * Author: Mike McLagan <mike.mclagan@linux.org>
+ *
+ * Changes:
+ * 0.15 Mike McLagan changed structure defs (packed)
+ * re-arranged flags
+ * added DLCI_RET vars
