Hi,
I'm working on TCP ECN support and I would like to kill these defines
from netinet/ip.h
#if 1
/* ECN RFC3168 obsoletes RFC2481, and these will be deprecated soon. */
#define IPTOS_CE 0x01
#define IPTOS_ECT 0x02
#endif
The are outdated and should no longer be used because that RFC has been
obsoleted. RFC 3168 uses a bit different bits:
#define IPTOS_ECN_NOTECT 0x00 /* not-ECT */
#define IPTOS_ECN_ECT1 0x01 /* ECN-capable transport (1) */
#define IPTOS_ECN_ECT0 0x02 /* ECN-capable transport (0) */
#define IPTOS_ECN_CE 0x03 /* congestion experienced */
#define IPTOS_ECN_MASK 0x03 /* ECN field mask */
The only consumer of the RFC 2481 defines is sbin/ipfw/ipfw2.c and
luigi@ accepted the attached patch.
Does anyone have any objection against the removal ?
Regards.
