If no one else has work in progress, I'll start implementing v2.
Which bit shall we use in the header to indicate the presence of an
extension?
Unfortunately, the length field is only one byte, which will not be big
enough for us.
Since no one has implemented a v2 sender yet, are we free to change v2?
struct proxy_hdr_v2 {
uint8_t sig[12]; /* hex 0D 0A 0D 0A 00 0D 0A 51 55 49 54 0A */
uint8_t ver; /* hex 02 */
uint8_t cmd; /* hex 00 or 01 */
uint8_t fam; /* protocol family and address */
uint8_t len; /* number of following bytes part of the header */
};
