This series fixes several issues I spotted while investigating
a 'tcp connection stalls with flow offload on' bug report.
I'm not sure if the original problem is fixed, however, the test script
in patch 5 will fail without the fixes from patches 1 and 2.
Patches 3 and 4 fix additional problems, however, these are by code
review only.
Florian Westphal (5):
netfilter: nf_flow_table: ignore DF bit setting
netfilter: nft_flow_offload: set liberal tracking mode for tcp
netfilter: nft_flow_offload: don't offload when sequence numbers need adjustment
netfilter: nft_flow_offload: IPCB is only valid for ipv4 family
selftests: netfilter: add flowtable test script
