In case we have a layer 3 interface on top of a bridge (VLAN / FID RIF),
then we should flood the following packet types to the router:

* Broadcast: If DIP is the broadcast address of the interface, then we
need to be able to get it to CPU by trapping it following route lookup.

* Reserved IP multicast (224.0.0.X): Some control packets (e.g. OSPF)
use this range and are trapped in the router block.

Instead of using sock_tx_timestamp, use skb_tx_timestamp to record
software transmit timestamp of a packet.

sock_tx_timestamp resets and overrides the tx_flags of the skb.
The function is intended to be called from within the protocol
layer when creating the skb, not from a device driver. This is
inconsistent with other drivers and will cause issues for TCP.

In TCP, we intend to sample the timestamps for the last byte
for each sendmsg/sendpage. For that reason, tcp_sendmsg calls
tcp_tx_timestamp only with the last skb that it generates.
For example, if a 128KB message is split into two 64KB packets
we want to sample the SND timestamp of the last packet. The current
code in the tun driver, however, will result in sampling the SND
timestamp for both packets.

Also, when the last packet is split into smaller packets for
retranmission (see tcp_fragment), the tun driver will record
timestamps for all of the retransmitted packets and not only the
last packet.

The current scatter-gather logic in gianfar is flawed, since
it does not consider the eTSEC's RxBD 'Data Length' field is
context depening: for the last fragment it contains the full
frame size, while fragments contain the fragment size, which
equals the value written to register MRBLR.

This causes data corruption as soon as the hardware starts
to fragment receiving frames. As a result, the size of
fragmented frames is increased by
(nr_frags - 1) * MRBLR

We first noticed this issue working with DSA, where an ICMP
request sized 1472 bytes causes the scatter-gather logic to
kick in. The full Ethernet frame (1518) gets increased by
DSA (4), GMAC_FCB_LEN (8), and FSL_GIANFAR_DEV_HAS_TIMER
(priv->padding=8) to a total of 1538 octets, which is
fragmented by the hardware and reconstructed by the driver
to a 3074 octet frame.

This patch fixes the problem by adjusting the size of
the last fragment.

It was tested by setting MRBLR to different multiples of
64, proving correct scatter-gather operation on frames
with up to 9000 octets in size.

The eTSEC register MRBLR defines the maximum space in
the RX buffers and is set to 1536 by gianfar. This
reasonably covers the common use case where the MTU
is kept at default 1500. In that case, the largest
Ethernet frame size of 1518 plus an optional
GMAC_FCB_LEN of 8, and an additional padding of 8
to handle FSL_GIANFAR_DEV_HAS_TIMER totals to 1534
and nicely fit within the chosen MRBLR.

Alas, if the eTSEC is attached to a DSA enabled switch,
the (E)DSA header extension (4 or 8 bytes) causes every
maximum sized frame to be fragmented by the hardware.

This patch increases the maximum RX buffer size by 8
and rounds up to the next multiple of 64, which the
hardware's defines as RX buffer granularity.

In b8247f09,

   "net: ip_finish_output_gso: If skb_gso_network_seglen exceeds MTU, allow segmentation for local udp tunneled skbs"

gso skbs arriving from an ingress interface that go through UDP
tunneling, are allowed to be fragmented if the resulting encapulated
segments exceed the dst mtu of the egress interface.

This aligned the behavior of gso skbs to non-gso skbs going through udp
encapsulation path.

However the non-gso vs gso anomaly is present also in the following
cases of a GRE tunnel:
 - ip_gre in collect_md mode, where TUNNEL_DONT_FRAGMENT is not set
   (e.g. OvS vport-gre with df_default=false)
 - ip_gre in nopmtudisc mode, where IFLA_GRE_IGNORE_DF is set

In both of the above cases, the non-gso skbs get fragmented, whereas the
gso skbs (having skb_gso_network_seglen that exceeds dst mtu) get dropped,
as they don't go through the segment+fragment code path.

Fix: Setting IPSKB_FRAG_SEGS if the tunnel specified IP_DF bit is NOT set.

Tunnels that do set IP_DF, will not go to fragmentation of segments.
This preserves behavior of ip_gre in (the default) pmtudisc mode.

If DAD fails with accept_dad set to 2, global addresses and host routes
are incorrectly left in place. Even though disable_ipv6 is set,
contrary to documentation, the addresses are not dynamically deleted
from the interface. It is only on a subsequent link down/up that these
are removed. The fix is not only to set the disable_ipv6 flag, but
also to call addrconf_ifdown(), which is the action to carry out when
disabling IPv6. This results in the addresses and routes being deleted
immediately. The DAD failure for the LL addr is determined as before
via netlink, or by the absence of the LL addr (which also previously
would have had to be checked for in case of an intervening link down
and up). As the call to addrconf_ifdown() requires an rtnl lock, the
logic to disable IPv6 when DAD fails is moved to addrconf_dad_work().

Previous behavior:

Since mlx5 has also the NONE e-switch mode, we must translate from mlx5
mode to devlink mode on the devlink eswitch mode get call, do that.

While here, remove the mlx5_ prefix from the static function helpers
that deal with the mode to comply with the rest of the code.

Avoid firmware command execution each time the switchdev HW ID attr get
call is made. We do that by reading the ID (PF NIC MAC) only once at
load time and store it on the representor structure.

The wrong key is used when extracting the address type field set by
the flower offload code. We have to use the control key and not the
basic key, fix that.

Set lastuse statistic, when number of packets is changed compared to
last query. This was wrongly dropped when bulk counter reading was added.
