sdomi a781106a89 Kernel/Net: Introduce proper pointers for payload calls
Unifying with other structures, this introduces m_payload for all
relevant structures, except the TCP header (which has a different
concept of payload than the rest).

This allows us to return a pointer directly instead of doing pointer
arithmetic to point to the end of the structure.
