Subject: Re: kern/125003: incorrect EtherIP header format.
Date: Thu, 26 Jun 2008 07:34:24 -0700
Hi,
It is unclear where the interoperability problem comes in.
struct etherip_header {
u_int8_t eip_ver; /* version/reserved */
u_int8_t eip_pad; /* required padding byte
*/
};
#define ETHERIP_VER_VERS_MASK 0x0f
#define ETHERIP_VERSION 0x03
From rfc3378,
1. Prepend the 16-bit EtherIP header to the MAC frame. The EtherIP
Version field MUST be set to 3 (three), and the EtherIP Reserved
field MUST be set to 0 (zero).
And the outgoing header is set to.
eiphdr.eip_ver = ETHERIP_VERSION & ETHERIP_VER_VERS_MASK;
eiphdr.eip_pad = 0;
Which would conform to the requirement. Can you describe the problem you
are seeing.
regards,
Andrew
