dhcp: put option 53 at the beginning2023_10_04.f851084
... unless it is listed in 55.
Many clients expect option 53 at the beginning.
mTCP has this code:
if ( resp->options[0] != 53 ) {
TRACE_WARN(( "Dhcp: first option was not a Dhcp msg type\n" ));
return;
}
wattcp32 has this:
static int DHCP_is_ack (void)
{
const BYTE *opt = (const BYTE*) &dhcp_in.dh_opt[4];
return (opt[0] == DHCP_OPT_MSG_TYPE && opt[1] == 1 && opt[2] == DHCP_ACK);
}
static int DHCP_is_nack (void)
{
const BYTE *opt = (const BYTE*) &dhcp_in.dh_opt[4];
return (opt[0] == DHCP_OPT_MSG_TYPE && opt[1] == 1 && opt[2] == DHCP_NAK);
}
