Change config symbol 6LOWPAN from type bool to type tristate, so
6LoWPAN can be built modular, just like IPV6

config 6LOWPAN

is this a regression from the previous CONFIG_6LOWPAN separation that we introduced? If it is, then it might be easiest if Dave just takes it into his net tree. Otherwise I take it through bluetooth-next.

I hadn't thought about that... Checking...

Yes, I believe this is a regression.

In v3.16, my allmodconfig build had:

CONFIG_IEEE802154_6LOWPAN=m
CONFIG_6LOWPAN_IPHC=m
CONFIG_BT_6LOWPAN=y

Without my patch it has:

CONFIG_6LOWPAN=y
CONFIG_IEEE802154_6LOWPAN=m
CONFIG_BT_6LOWPAN=m

and iphc is what's in net/6lowpan/built-in.o now.
