TC shared blocks allow multiple qdiscs to be grouped together and filters
shared between them. Currently the chains of filters attached to a block
are only flushed when the block is removed. If a qdisc is removed from a
block but the block still exists, flow del messages are not passed to the
callback registered for that qdisc. For the NFP, this presents the
possibility of rules still existing in hw when they should be removed.

Prevent binding to shared blocks until the kernel can send per qdisc del
messages when block unbinds occur.

tcf_block_shared() was not used outside of the core until now, so also
add an empty implementation for builds with CONFIG_NET_CLS=n.

Previously it was not possible to distinguish between mpls ether types and
other ether types. This leads to incorrect classification of offloaded
filters that match on mpls ether type. For example the following two
filters overlap:

 # tc filter add dev eth0 parent ffff: \
    protocol 0x8847 flower \
    action mirred egress redirect dev eth1

 # tc filter add dev eth0 parent ffff: \
    protocol 0x0800 flower \
    action mirred egress redirect dev eth2

The driver now correctly includes the mac_mpls layer where HW stores mpls
fields, when it detects an mpls ether type. It also sets the MPLS_Q bit to
indicate that the filter should match mpls packets.

When unplugging an r8152 adapter while the interface is UP, the NIC
becomes unusable.  usb->disconnect (aka rtl8152_disconnect) deletes
napi. Then, rtl8152_disconnect calls unregister_netdev and that invokes
netdev->ndo_stop (aka rtl8152_close). rtl8152_close tries to
napi_disable, but the napi is already deleted by disconnect above. So
the first while loop in napi_disable never finishes. This results in
complete deadlock of the network layer as there is rtnl_mutex held by
unregister_netdev.

So avoid the call to napi_disable in rtl8152_close when the device is
already gone.

The other calls to usb_kill_urb, cancel_delayed_work_sync,
netif_stop_queue etc. seem to be fine. The urb and netdev is not

When using s/w buffer management, buffers are allocated and DMA mapped.
When doing so on an arm64 platform, an offset correction is applied on
the DMA address, before storing it in an Rx descriptor. The issue is
this DMA address is then used later in the Rx path without removing the
offset correction. Thus the DMA address is wrong, which can led to
various issues.

This patch fixes this by removing the offset correction from the DMA

When injecting frames in the Ocelot switch driver an injection header
(IFH) should be used to configure various parameters related to a given
frame, such as the port onto which the frame should be departed or its
vlan id. Other parameters in the switch configuration can led to an
injected frame being sent without an IFH but this led to various issues
as the per-frame parameters are then not used. This is especially true
when using multiple ports for injection.

The IFH was injected with the wrong endianness which led to the switch
not taking it into account as the IFH_INJ_BYPASS bit was then unset.
(The bit tells the switch to use the IFH over its internal
configuration). This patch fixes it.

In addition to the endianness fix, the IFH is also fixed. As it was
(unwillingly) unused, some of its fields were not configured the right
way.

After commit 88078d98 ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE
are friends"), sungem owners reported the infamous "eth0: hw csum failure"
message.

CHECKSUM_COMPLETE has in fact never worked for this driver, but this
was masked by the fact that upper stacks had to strip the FCS, and
therefore skb->ip_summed was set back to CHECKSUM_NONE before
my recent change.

Driver configures a number of bytes to skip when the chip computes
the checksum, and for some reason only half of the Ethernet header
was skipped.

Then a second problem is that we should strip the FCS by default,
unless the driver is updated to eventually support NETIF_F_RXFCS in
the future.

Finally, a driver should check if NETIF_F_RXCSUM feature is enabled
or not, so that the admin can turn off rx checksum if wanted.

Using skb_reserve(skb, I40E_SKB_PAD + (xdp->data - xdp->data_hard_start))
is clearly wrong since I40E_SKB_PAD already points to the offset where
the original xdp->data was sitting since xdp->data_hard_start is defined
as xdp->data - i40e_rx_offset(rx_ring) where latter offsets to I40E_SKB_PAD
when build skb is used.

However, also before cc5b114d ("bpf, i40e: add meta data support")
this seems broken since bpf_xdp_adjust_head() helper could have been used
to alter headroom and enlarge / shrink the frame and with that the assumption
that the xdp->data remains unchanged does not hold and would push a bogus
packet to upper stack.

ixgbe got this right in 92470808 ("ixgbe: add XDP support for pass and

Do not advertise DCBX_LLD_MANAGED capability i.e., do not allow
external agent to manage the dcbx/lldp negotiation. MFW acts as lldp agent
for qed* devices, and no other lldp agent is allowed to coexist with mfw.

Also updated a debug print, to not to display the redundant info.

Fixes: a1d8d8a5 ("qed: Add dcbnl support.")
