Re: [PATCH] 6lowpan: add a license to 6lowpan_iphc module

Since commit 8df8c56a5abc, 6lowpan_iphc is a module of its own.

Unfortunately, it lacks some infrastructure to behave like a
good kernel citizen:

 kernel: 6lowpan_iphc: module license 'unspecified' taints kernel.
 kernel: Disabling lock debugging due to kernel taint

This patch adds the basic MODULE_LICENSE(); with GPL license:
the code was copied from net/ieee802154/6lowpan.c which is GPL
and the module exports symbol with EXPORT_SYMBOL_GPL();.
