From: Florian Westphal fw@strlen.de

[ Upstream commit 4c82fd0abb87e20d0d68ef5237e74732352806c8 ]

nft_ct exposes this bit to userspace. This used to be

#define NF_CT_STATE_UNTRACKED_BIT (1 << (IP_CT_NUMBER + 1)) (IP_CT_NUMBER is 5, so this was 0x40)

.. but this got changed to 8 (0x100) when the untracked object got removed. Replace this with a literal 6 to prevent further incompatible changes in case IP_CT_NUMBER ever increases.
