By moving the skb delivery out of IPHC you automatically fix the nightmare which is returning a mixture of NET_RX codes with error codes. IPHC now only returns error codes or success. Delivery is done where is should be in the receive function and can deal with NET_RX codes.
ok. When this is a part of the fix and 1/3 "prepare" the fix, then put
this handling into patch "1/3" to really fix the issue from patch 1/3.
