In function `tc_dump_tfilter`, the attributes array is parsed via
tcf_tfilter_dump_policy which only describes TCA_DUMP_FLAGS. However,
the NLA TCA_CHAIN is also accessed with `nla_get_u32`.
The access to TCA_CHAIN is introduced in commit 5bc1701881e3 ("net:
sched: introduce multichain support for filters") and no nla_policy is
provided for parsing at that point. Later on, tcf_tfilter_dump_policy is
introduced in commit f8ab1807a9c9 ("net: sched: introduce terse dump
flag") while still ignoring the fact that TCA_CHAIN needs a check. This
patch does that by complementing the policy to allow the access
discussed here can be safe as other cases just choose rtm_tca_policy as
the parsing policy.

Commit 13e59344fb9d ("net: ethtool: add support for symmetric-xor RSS hash")
adds a check to the ethtool set_rxnfc operation, which checks the RX
flow hash if the flag RXH_XFRM_SYM_XOR is set. This flag is introduced
with the same commit. It calls the ethtool get_rxfh operation to get the
RX flow hash data. If get_rxfh is not supported, then EOPNOTSUPP is
returned.
There are driver like tsnep, macb, asp2, genet, gianfar, mtk, ... which
support the ethtool operation set_rxnfc but not get_rxfh. This results
in EOPNOTSUPP returned by ethtool_set_rxnfc() without actually calling
the ethtool operation set_rxnfc. Thus, set_rxnfc got broken for all
these drivers.
Check RX flow hash in ethtool_set_rxnfc() only if driver supports RX
flow hash.

established connections counter MIB_CURRESTAB in diag.sh. Invoke it
to check the counter during the connection after every chk_msk_inuse().

This patch adds a new helper chk_cestab_nr() to check the current
established connections counter MIB_CURRESTAB. Set the newly added
variables cestab_ns1 and cestab_ns2 to indicate how many connections
are expected in ns1 or ns2.
Invoke check_cestab() to check the counter during the connection in
do_transfer() and invoke chk_cestab_nr() to re-check it when the
connection closed. These checks are embedded in add_tests().

Add a new MIB counter named MPTCP_MIB_CURRESTAB to count current
established MPTCP connections, similar to TCP_MIB_CURRESTAB. This is
useful to quickly list the number of MPTCP connections without having to
iterate over all of them.
This patch adds a new helper function mptcp_set_state(): if the state
switches from or to ESTABLISHED state, this newly added counter is
incremented. This helper is going to be used in the following patch.
Similar to MPTCP_INC_STATS(), a new helper called MPTCP_DEC_STATS() is
also needed to decrement a MIB counter.

selftest/net: Some more TCP-AO selftest post-merge fixups
Note that there's another post-merge fix for TCP-AO selftests, but that
doesn't conflict with these, so I don't resend that:
