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!

+ *   communications for the Linux operating system. Support of llc class
+ *   one and class two is provided via SOCK_DGRAM and SOCK_STREAM
+ *   respectively.
+ *
+ *   An llc2 connection is (mac + sap), only one llc2 sap connection
+ *   is allowed per mac. Though one sap may have multiple mac + sap

+/*
+ * llc_c_ev.c - Connection component state transition event qualifiers
+ *
+ * A 'state' consists of a number of possible event matching functions,
+ * the actions associated with each being executed when that event is
+ * matched; a 'state machine' accepts events in a serial fashion from an
+ * event queue. Each event is passed to each successive event matching
+ * function until a match is made (the event matching function returns
+ * success, or '0') or the list of event matching functions is exhausted.
+ * If a match is made, the actions associated with the event are executed
+ * and the state is changed to that event's transition state. Before some
+ * events are recognized, even after a match has been made, a certain
+ * number of 'event qualifier' functions must also be executed. If these
+ * all execute successfully, then the event is finally executed.
+ *
+ * These event functions must return 0 for success, to show a matched
+ * event, of 1 if the event does not match. Event qualifier functions
+ * must return a 0 for success or a non-zero for failure. Each function
+ * is simply responsible for verifying one single thing and returning
+ * either a success or failure.
+ *
+ * All of followed event functions are described in 802.2 LLC Protocol
+ * standard document except two functions that we added that will explain
+ * in their comments, at below.
