Trigger a port mod message to request an MTU change on the NIC when any
physical port representor is assigned a new MTU value. The driver waits
10 msec for an ack that the FW has set the MTU. If no ack is received the
request is rejected and an appropriate warning flagged.
Rather than maintain an MTU queue per repr, one is maintained per app.
Because the MTU ndo is protected by the rtnl lock, there can never be
contention here. Portmod messages from the NIC are also protected by
rtnl so we first check if the portmod is an ack and, if so, handle outside
rtnl and the cmsg work queue.
Acks are detected by the marking of a bit in a portmod response. They are
then verfied by checking the port number and MTU value expected by the
app. If the expected MTU is 0 then no acks are currently expected.
Also, ensure that the packet headroom reserved by the flower firmware is
considered when accepting an MTU change on any repr.

Rename the 'change_mtu' app callback to 'check_mtu'. This is called
whenever an MTU change is requested on a netdev. It can reject the
change but is not responsible for implementing it.
Introduce a new 'repr_change_mtu' app callback that is hit when the MTU
of a repr is to be changed. This is responsible for performing the MTU
change and verifying it.

phylink: API changes
This patch series contains two API changes to PHYLINK which will later be used
by DSA to migrate to PHYLINK. Because these are API changes that impact other
outstanding work (e.g: MVPP2) I would rather get them included sooner to minimize
conflicts.
Thank you!
Changes in v2:
- added missing documentation to mac_link_{up,down} that the interface
must be configured in mac_config()

In preparation for having DSA transition entirely to PHYLINK, we need to pass a
PHY interface type to the mac_link_{up,down} callbacks because we may have to
make decisions on that (e.g: turn on/off RGMII interfaces etc.). We do not pass
an entire phylink_link_state because not all parameters (pause, duplex etc.) are
defined when the link is down, only link and interface are.
Update mvneta accordingly since it currently implements phylink_mac_ops.

net: Broadcom drivers coalescing fixes
Following Tal's review of the adaptive RX/TX coalescing feature added to the
SYSTEMPORT and GENET driver a number of things showed up:
- adaptive TX coalescing is not actually a good idea with the current way
the estimator will program the ring, this results in a higher CPU load, NAPI
on TX already does a reasonably good job at maintaining the interrupt count low
- both SYSTEMPORT and GENET would suffer from the same issues while configuring
coalescing parameters where the values would just not be applied correctly
based on user settings, so we fix that too
Tal, thanks again for your feedback, I would appreciate if you could review that
the new behavior appears to be implemented correctly.
Thanks!
Changes in v2:
- added Tal's reviewed-by to the first patch
- split DIM initialization from coalescing parameters initialization
- avoid duplicating the same code in bcmgenet_set_coalesce() when configuring RX rings
- fixed the condition where default DIM parameters would be applied when
adaptive RX coalescing would be enabled, do this only if it was disabled before
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
There were a number of issues with setting the RX coalescing parameters:
- we would not be preserving values that would have been configured
across close/open calls, instead we would always reset to no timeout
and 1 interrupt per packet, this would also prevent DIM from setting its
default usec/pkts values
- when adaptive RX would be turned on, we woud not be fetching the
default parameters, we would stay with no timeout/1 packet per interrupt
until the estimator kicks in and changes that
- finally disabling adaptive RX coalescing while providing parameters
would not be honored, and we would stay with whatever DIM had previously
determined instead of the user requested parameters

NETIF_F_HW_VLAN_[CS]TAG_FILTER features require more than just a bit
flip in dev->features in order to keep the driver in a consistent state.
These features notify the driver of each added/removed vlan, but toggling
of vlan-filter does not notify the driver accordingly for each of the
existing vlans.
This patch implements a similar solution to NETIF_F_RX_UDP_TUNNEL_PORT
behavior (which notifies the driver about UDP ports in the same manner
that vids are reported).
Each toggling of the features propagates to the 8021q module, which
iterates over the vlans and call add/kill ndo accordingly.

mark_source_chains is not the correct place for such a check, as it

(following rules are known to be unreachable). It seems preferrable to
fix libiptc instead, so remove this check again.

During heavy tx traffic, control messages (sent by liquidio driver to NIC
firmware) sometimes do not get processed in a timely manner. Reason is:
the low-level metadata of control messages and that of egress network
packets indicate that they have the same priority.
Fix it by setting a higher priority for control messages through the new
ctrl_qpg field in the oct_txpciq struct. It is the NIC firmware that does
the actual setting of priority by writing to the new ctrl_qpg field; the
host driver treats that value as opaque and just assigns it to pki_ih3->qpg
