+
+Notes:
+
+ Note that a previous version of the Micrel ksz9021rl/rn Data Sheet
+ was missing extended register 106 (transmit data pad skews), and
+ incorrectly specified the ps per step as 200ps/step instead of
+ 120ps/step. The latest update to this document reflects the latest
+ revision of the Micrel specification even though usage in the kernel
+ still reflects that incorrect document.

+/**
+ * DOC: Extensibility
+ *
+ * Originally, we had planned to allow backward and forward compatible
+ * changes by just adding fields at the end of the structure that are
+ * then not reported on older kernels on read(), and not written to by
+ * older kernels on write(), with the kernel reporting the size it did
+ * accept as the result.
+ *
+ * This would have allowed userspace to detect on read() and write()
+ * which kernel structure version it was dealing with, and if was just
+ * recompiled it would have gotten the new fields, but obviously not
+ * accessed them, but things should've continued to work.
+ *
+ * Unfortunately, while actually exercising this mechanism to add the
+ * hard block reasons field, we found that userspace (notably systemd)
+ * did all kinds of fun things not in line with this scheme:
+ *
+ * 1. treat the (expected) short writes as an error;
+ * 2. ask to read sizeof(struct rfkill_event) but then compare the
+ * actual return value to RFKILL_EVENT_SIZE_V1 and treat any
+ * mismatch as an error.
+ *
+ * As a consequence, just recompiling with a new struct version caused
+ * things to no longer work correctly on old and new kernels.
+ *
+ * Hence, we've rolled back &struct rfkill_event to the original version
+ * and added &struct rfkill_event_ext. This effectively reverts to the
+ * old behaviour for all userspace, unless it explicitly opts in to the
+ * rules outlined here by using the new &struct rfkill_event_ext.
+ *
+ * Userspace using &struct rfkill_event_ext must adhere to the following
+ * rules
*
- * One exception is the kernel -- we already have two event sizes in
- * that we've made the 'hard' member optional since our only option
- * is to ignore it anyway.
+ * 1. accept short writes, optionally using them to detect that it's
+ * running on an older kernel;
+ * 2. accept short reads, knowing that this means it's running on an
+ * older kernel;
+ * 3. treat reads that are as long as requested as acceptable, not
+ * checking against RFKILL_EVENT_SIZE_V1 or such.
