Fortville and Fort Park devices are often on different firmware release
schedules. This change relaxes the minor version warning message,
so it is only displayed for older FW warning version for old
firmware Fortville 3 or earlier.

i40e_print_link_message() is intended to compare new
link state with current link state and print log message
only if the new state is different from current state.
However in current driver the new state does not get updated
when link is going down because of the if condition. When an
interface is brought down, vsi->state is set to I40E_VSI_DOWN
in i40e_vsi_close() and later i40e_print_link_message() does
not get invoked in i40e_link_event due to if condition. Hence
link down message doesn't appear when link is going down. The
down state is seen later during i40e_open() and old state
gets printed. The actual link state doesn't get updated in
i40e_close() or i40e_open() but when i40e_handle_link_event is
called inside i40e_clean_adminq_subtask.
This change allows i40e_print_link_message() to be called when
interface is going down and keeps the state information updated.

In current driver, when ifconfig ethx up is done, the link state
doesn't transition to UP inside i40e_open(). It changes after AQ
command response is handled in i40e_handle_link_event().
When pf->hw.phy.link_info.link_info is DOWN inside i40e_open(),
The state is transient and invalid. So log message gets printed
based on incorrect info (i.e link_info and an_info).
This commit removes check for unqualified module inside
i40e_up_complete(). The existing check in i40e_handle_link_event()
logs the error message based on correct link state information.

Current buffer allocation can only happen at init, when
doing buffer reallocation after init, care must be taken
care of memory which priv_buf points to.
This patch fixes it by using a dynamic allocated temporary
memory. Because we only do buffer reallocation at init or

used at buffer allocation process, so it is ok to use a

Add functionality for calling the multicast routing offloading logic upon
MFC and VIF add and delete notifications. In addition, call the multicast
routing upon RIF addition and deletion events.
As the multicast routing offload logic may sleep, the actual calls are done
in a deferred work. To ensure the MFC object is not freed in that interval,
a reference is held to it. In case of a failure, the abort mechanism is
used, which ejects all the routes from the hardware and triggers the
traffic to flow through the kernel.
Note: At that stage, the FIB notifications are still ignored, and will be
enabled in a further patch.

Currently, the mlxsw Spectrum driver offloads only either the RT_TABLE_MAIN
FIB table or the VRF tables, so the RT_TABLE_LOCAL table is squashed to the
RT_TABLE_MAIN table to allow local routes to be offloaded too.
By default, multicast MFC routes which are not assigned to any user
requested table are put in the RT_TABLE_DEFAULT table.
Due to the fact that offloading multicast MFC routes support in Spectrum
router logic is going to be introduced soon, squash the default table to
MAIN too.

Implement the multicast routing hardware API introduced in previous patch
for the specific spectrum hardware.
The spectrum hardware multicast routes are written using the RMFT2 register
and point to an ACL flexible action set. The actions used for multicast
routes are:
- Counter action, which allows counting bytes and packets on multicast
routes.
- Multicast route action, which provide RPF check and do the actual packet
duplication to a list of RIFs.
- Trap action, in the case the route action specified by the called is
trap.

Add the multicast router offloading logic, which is in charge of handling
the VIF and MFC notifications and translating it to the hardware logic API.
The offloading logic has to overcome several obstacles in order to safely
comply with the kernel multicast router user API:
- It must keep track of the mapping between VIFs to netdevices. The user
can add an MFC cache entry pointing to a VIF, delete the VIF and add
re-add it with a different netdevice. The offloading logic has to handle
this in order to be compatible with the kernel logic.
- It must keep track of the mapping between netdevices to spectrum RIFs,
as the current hardware implementation assume having a RIF for every
port in a multicast router.
- It must handle routes pointing to pimreg device to be trapped to the
kernel, as the packet should be delivered to userspace.
- It must handle routes pointing tunnel VIFs. The current implementation
does not support multicast forwarding to tunnels, thus routes that point
to a tunnel should be trapped to the kernel.
- It must be aware of proxy multicast routes, which include both (*,*)
routes and duplicate routes. Currently proxy routes are not offloaded
and trigger the abort mechanism: removal of all routes from hardware and
triggering the traffic to go through the kernel.
The multicast routing offloading logic also updates the counters of the
offloaded MFC routes in a periodic work.

We implement this for the default ixgbe_build_skb() variant. For the

neither xdp_adjust_head() nor xdp_adjust_meta() can be used with this.

This work enables generic transfer of metadata from XDP into skb. The
basic idea is that we can make use of the fact that the resulting skb
must be linear and already comes with a larger headroom for supporting
bpf_xdp_adjust_head(), which mangles xdp->data. Here, we base our work
on a similar principle and introduce a small helper bpf_xdp_adjust_meta()
for adjusting a new pointer called xdp->data_meta. Thus, the packet has
a flexible and programmable room for meta data, followed by the actual
packet data. struct xdp_buff is therefore laid out that we first point
to data_hard_start, then data_meta directly prepended to data followed
by data_end marking the end of packet. bpf_xdp_adjust_head() takes into
account whether we have meta data already prepended and if so, memmove()s
this along with the given offset provided there's enough room.
xdp->data_meta is optional and programs are not required to use it. The
rationale is that when we process the packet in XDP (e.g. as DoS filter),
we can push further meta data along with it for the XDP_PASS case, and
give the guarantee that a clsact ingress BPF program on the same device
can pick this up for further post-processing. Since we work with skb
there, we can also set skb->mark, skb->priority or other skb meta data
out of BPF, thus having this scratch space generic and programmable
allows for more flexibility than defining a direct 1:1 transfer of
potentially new XDP members into skb (it's also more efficient as we
don't need to initialize/handle each of such new members). The facility
also works together with GRO aggregation. The scratch space at the head
of the packet can be multiple of 4 byte up to 32 byte large. Drivers not
yet supporting xdp->data_meta can simply be set up with xdp->data_meta
as xdp->data + 1 as bpf_xdp_adjust_meta() will detect this and bail out,
such that the subsequent match against xdp->data for later access is
guaranteed to fail.
The verifier treats xdp->data_meta/xdp->data the same way as we treat
xdp->data/xdp->data_end pointer comparisons. The requirement for doing
the compare against xdp->data is that it hasn't been modified from it's
original address we got from ctx access. It may have a range marking
already from prior successful xdp->data/xdp->data_end pointer comparisons
though.
