octeontx2-af: fix detection of IP layer
[ Upstream commit 404dc0fd6fb0bb942b18008c6f8c0320b80aca20 ] Checksum and length checks are not enabled for IPv4 header with options and IPv6 with extension headers. To fix this a change in enum npc_kpu_lc_ltype is required which will allow adjustment of LTYPE_MASK to detect all types of IP headers.
