When creating new states with seq set in xfrm_usersa_info, we walk through all the states already installed in that netns to find a matching ACQUIRE state (__xfrm_find_acq_byseq, called from xfrm_state_add). This causes severe slowdowns on systems with a large number of states. This patch introduces a hashtable using x->km.seq as key, so that the corresponding state can be found in a reasonable time.
