Re: NDIS ntohs/htons

The data of the MAC header and packet payload in the egress packet is in
network byte order.

Hi,

I am trying to inspect the Ethertype/length field in the Ethernet header
of
an egress NDIS packet handed to the miniport by a protocol driver. What
byte-order does NDIS use for the header and payload? Do I need to put the
Ethertype/length value through a call to ntohs() or htons() or just use
the
value as is?

I am assuming for an ingress NDIS packet, the byte order is network byte
order so I would need to use ntohs() to inpect a short. Is this correct?

Thanks.
