Re: [PATCH linux-wpan 3/3] ieee802154: 6lowpan: Drop PACKET_OTHERHOST skbs in 6lowpan

[Alexander Aring <alex.aring@gmail.com>]

Simon,

I applied now this patch to linux-wpan-next/testing, this should fix
routing problems. For the upcomming issue "always set PACKET_HOST"... I
put it on the TODO list. ;-)

Thanks.

I will send it to bluetooth-next now, then Martin can base his patches
on it.
