Subject: [PATCH ipsec-next 0/2] xfrm: scalability enhancements for policy database

This patchset enables to hash more policies than just non-prefixed
ones: hash policies whose prefix lengths are greater or equal to
configurable thresholds.

These thresholds are configured via /proc entries:

/proc/sys/net/ipv4/xfrm4_policy_hash_tresh: 32 32
/proc/sys/net/ipv6/xfrm6_policy_hash_tresh: 128 128

Christophe Gouault (2):
      xfrm: hash prefixed policies based on preflen thresholds
      xfrm: configure policy hash table thresholds by /proc
