JuanJo, why did you do:

#define IPSEC_ALG_STRUCT_COMMON stuff

struct ipsec_alg {
	IPSEC_ALG_STRUCT_COMMON
};
/* 
 * 	Note the const in cbc_encrypt IV arg:
 * 	some ciphers like to toast passed IV (eg. 3DES): make a local IV copy
 */
struct ipsec_alg_enc {
	IPSEC_ALG_STRUCT_COMMON
	unsigned ixt_e_keylen;		/* raw key length in bytes          */


instead of doing:

struct ipsec_alg {
       stuff;		 
};

struct ipsec_alg_eng {
       struct ipsec_alg common;
       unsigned ixt_e_keylen;
       ....
};
