There is no hardware supporting ct helper offload. However, prior to this
patch, a flower filter with a helper in the ct action can be successfully
set into the HW, for example (eth1 is a bnxt NIC):
# tc qdisc add dev eth1 ingress_block 22 ingress
# tc filter add block 22 proto ip flower skip_sw ip_proto tcp \
dst_port 21 ct_state -trk action ct helper ipv4-tcp-ftp
# tc filter show dev eth1 ingress
filter block 22 protocol ip pref 49152 flower chain 0 handle 0x1
eth_type ipv4
ip_proto tcp
dst_port 21
ct_state -trk
skip_sw
in_hw in_hw_count 1 <----
action order 1: ct zone 0 helper ipv4-tcp-ftp pipe
index 2 ref 1 bind 1
used_hw_stats delayed
This might cause the flower filter not to work as expected in the HW.
This patch avoids this problem by simply returning -EOPNOTSUPP in
tcf_ct_offload_act_setup() to not allow to offload flows with a helper
in act_ct.
