From: Gerrit Renker <gerrit@xxxxxxxxxxxxxx> [DCCP]: Use AF-independent rebuild_header routine This fixes a nasty bug: dccp_send_reset() is called by both DCCPv4 and DCCPv6, but uses inet_sk_rebuild_header() in each case. This leads to unpredictable and weird behaviour: under some conditions, DCCPv6 Resets were sent, in other not. The fix is to use the AF-independent rebuild_header routine.
