Subject: Re: [PATCH 0/2] linux-wpan-next: lowpan_rcv - skb is freed within function and fix return values.

Hi Alex,

>>> Currently it is up to the functions below lowpan_rcv to free the skb on error
>>>   conditions.  This patch now removes all the UAPI error codes and process data
>>>   now returns -1 if there is a problem.  In this scenario lowpan_rcv will free
>>>   the skb and return NET_RX_DROP.  This also fixes the problem where
>>>   NET_RX_SUCCESS is returned on error
>>> 
>>> Martin Townsend (2):
>>> Remove dev parameter from skb_delivery_cb in 6lowpan.
>>> Change lowpan_rcv so skb is freed within function and fix return
>>>   values.

if patches are based on bluetooth-next, then we have no problem here. I can easily merge them.
