When creating a static bond (e.g. balance-xor), all ports will always
be enabled. This is set, and the corresponding notification is sent
out, before the port is linked to the bond upper.

In the offloaded case, this ordering is hard to deal with.

The lower will first see a notification that it can not associate with
any bond. Then the bond is joined. After that point no more
notifications are sent, so all ports remain disabled.

This change simply sends an extra notification once the port has been
linked to the upper to synchronize the initial state.

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'mlxsw_pci_queue_init()' and
'mlxsw_pci_fw_area_init()' GFP_KERNEL can be used because both functions
are already using this flag and no lock is acquired.

When memory is allocated in 'mlxsw_pci_mbox_alloc()' GFP_KERNEL can be used
because it is only called from the probe function and no lock is acquired
in the between.
The call chain is:
  --> mlxsw_pci_probe()
    --> mlxsw_pci_cmd_init()
      --> mlxsw_pci_mbox_alloc()

While at it, also replace the 'dma_set_mask/dma_set_coherent_mask' sequence
by a less verbose 'dma_set_mask_and_coherent() call.

net/mlx5e: E-Switch, Offload all chain 0 priorities when modify header and forward action is not supported

Miss path handling of tc multi chain filters (i.e. filters that are
defined on chain > 0) requires the hardware to communicate to the
driver the last chain that was processed. This is possible only when
the hardware is capable of performing the combination of modify header
and forward to table actions. Currently, if the hardware is missing
this capability then the driver only offloads rules that are defined
on tc chain 0 prio 1. However, this restriction can be relaxed because
packets that miss from chain 0 are processed through all the
priorities by tc software.

Allow the offload of all the supported priorities for chain 0 even
when the hardware is not capable to perform modify header and goto
table actions.
