From Eyal Birger. 2) Fix a kernel warning in case XFRM encap type is not available. From Eyal Birger. 3) Fix ESN wrap around for GSO to avoid a double usage of a sequence number. From Christian Langrock. 4) Fix a send_acquire race with pfkey_register. From Herbert Xu. 5) Fix a list corruption panic in __xfrm_state_delete(). Thomas Jarosch. 6) Fix an unchecked return value in xfrm6_init().
