Hello together, I'm a bit confused on how to retrieve data from a socket buffer correctly. If I have a pointer to the sk_buff struct and now I want to retrieve the last two octets from the data, say (skb->tail - 2), do I need to use u16 fcs = get_unaligned(skb->tail - 2); or even u16 fcs = __le16_to_cpu(skb->tail - 2); or anything else? What assumptions can be made about the socket buffer concerning data alignment and endianess? Thanks for any help, Martin -- Kernelnewbies: Help each other learn about the Linux kernel.
