After the previous patch, all the callers of ndo_select_queue()
provide as a 'fallback' argument netdev_pick_tx.
The only exceptions are nested calls to ndo_select_queue(),
which pass down the 'fallback' available in the current scope
- still netdev_pick_tx.
We can drop such argument and replace fallback() invocation with
netdev_pick_tx(). This avoids an indirect call per xmit packet
in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen)
with device drivers implementing such ndo. It also clean the code
a bit.
Tested with ixgbe and CONFIG_FCOE=m
With pktgen using queue xmit:

T6 introduced a Timer Mechanism in SGE called the
SGE Doorbell Queue Timer. With this we can now configure
TX Queues to get CIDX Updates when:
Time(CIDX == PIDX) >= Timer
Previously we rely on TX Queue Status Page updates by hardware
for DMA completions. This will make Hardware/Firmware actually
deliver the CIDX Updates as Ingress Queue messages with
commensurate Interrupts.
So we now have a new RX Path component for processing CIDX Updates
and reclaiming TX Descriptors faster.

This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.

This fix programs hash region with the mac address, when TCAM
addtion fails for {t4/t4vf}_change_mac(). Since the locally maintained
