Ethtool ntuple filters with FLOW_RSS were originally defined as adding
the base queue ID (ring_cookie) to the value from the indirection table,
so that the same table could distribute over more than one set of queues
when used by different filters.
However, some drivers / hardware ignore the ring_cookie, and simply use
the indirection table entries as queue IDs directly. Thus, for drivers
which have not opted in by setting ethtool_ops.cap_rss_rxnfc_adds to
declare that they support the original (addition) semantics, reject in
ethtool_set_rxnfc any filter which combines FLOW_RSS and a nonzero ring.
(For a ring_cookie of zero, both behaviours are equivalent.)
Set the cap bit in sfc, as it is known to support this feature.

The previous patch changed when we increment the RX queue's rx_packets
counter, to match the semantics of netdev per-queue stats. The
differences between the old and new counts are scatter errors (which
produce a WARN_ON) and this counter, which is incremented by
efx_rx_packet__check_len() when an RX packet (which was placed in a
single buffer by SG, i.e. n_frags == 1) has a length (from the RX
event) which is too long to fit in the RX buffer. If this occurs, we
drop the packet and fire a ratelimited netif_err().
The counter previously was not reported anywhere; add it to ethtool -S
output to ensure users still have this information.

Just RX and TX packet counts and TX bytes for now. We do not
have per-queue RX byte counts, which causes us to fail
stats.pkt_byte_sum selftest with "Drivers should always report
basic keys" error.
Per-queue counts are since the last time the queue was inited
(typically by efx_start_datapath(), on ifup or reconfiguration);
device-wide total (efx_get_base_stats()) is since driver probe.
This is not the same lifetime as rtnl_link_stats64, which uses
firmware stats which count since FW (re)booted; this can cause a
"Qstats are lower" or "RTNL stats are lower" failure in
stats.pkt_byte_sum selftest.
Move the increment of rx_queue->rx_packets to match the semantics
specified for netdev per-queue stats, i.e. just before handing
the packet to XDP (if present) or the netstack (through GRO).
This will affect the existing ethtool -S output which also

marvell/otx2 and mvpp2 do not support setting different
keys for different RSS contexts. Contexts have separate
indirection tables but key is shared with all other contexts.
This is likely fine, indirection table is the most important
piece.
Don't report the key-related parameters from such drivers.
This prevents driver-errors, e.g. otx2 always writes
the main key, even when user asks to change per-context key.
The second reason is that without this change tracking
the keys by the core gets complicated. Even if the driver
correctly reject setting key with rss_context != 0,
change of the main key would have to be reflected in
the XArray for all additional contexts.
Since the additional contexts don't have their own keys
not including the attributes (in Netlink speak) seems
intuitive. ethtool CLI seems to deal with it just fine.
Having to set the flag in majority of the drivers is
a bit tedious but not reporting the key is a safer
default.

This is a cleanup patch, making code a bit more concise.
1) Use skb_network_offset(skb) in place of
(skb_network_header(skb) - skb->data)
2) Use -skb_network_offset(skb) in place of
(skb->data - skb_network_header(skb))
3) Use skb_transport_offset(skb) in place of
(skb_transport_header(skb) - skb->data)
4) Use skb_inner_transport_offset(skb) in place of
(skb_inner_transport_header(skb) - skb->data)
