Currently the function i40e_napi-poll() returns 0 when it clean completely
the Rx rings, but this foul budget accounting in core code.

Fix this by returning the actual work done, capped to budget - 1, since
the core doesn't allow to return the full budget when the driver modifies
the NAPI status

This is based on a similar change that was made for the ixgbe driver by
Paolo Abeni.

A previous commit 53cb6e9e ("i40e: Removal of workaround for simple
MAC address filter deletion") removed a workaround for some
firmware versions which was reported to not be necessary in production
NICs. Unfortunately this workaround is necessary in some configurations,
specifically the Ethernet Controller XL710 for 40GbE QSFP+ (8086:1583).

Without this patch, the mentioned NICs with current firmware exhibit
issues when adding VLANs, as outlined by the following reproduction:

  $modprobe i40e
  $ip link set <device> up
  $ip link add link <device> vlan100 type vlan id 100
  $dmesg | tail
  <snip>
  kernel: i40e 0000:82:00.0: Error I40E_AQ_RC_EINVAL adding RX
filters on PF, promiscuous mode forced on

This results in filters being marked as FAILED and setting the device in
promiscuous mode.

The root cause of receiving the -EINVAL error response appears to be due
to a conflict with the default MAC filter which still exists on the
default firmware for this device. Attempting to add a new VLAN filter on
the default MAC address conflicts with the IGNORE_VLAN setting on the
default rule.

A previous workaround added to ensure receipt of all broadcast frames
incorrectly set the broadcast promiscuous mode unconditionally
regardless of active VLAN status.

Replace this partial workaround with a complete solution that sets the
broadcast promiscuous filters in i40e_sync_vsi_filters. This new method
sets the promiscuous mode based on when broadcast filters are added or
removed.

I40E_VLAN_ANY will request a broadcast filter for all VLANs, (as we're
in untagged mode) while a broadcast filter on a specific VLAN will only
request broadcast for that VLAN.

Thus, we restore addition of broadcast filter to the array, but we add
special handling for these such that they enable the broadcast
promiscuous mode instead of being sent as regular filters.

The end result is that we will correctly receive all broadcast packets
(even those with a *source* address equal to the broadcast address) but
will not receive packets for which we don't have an active VLAN filter.

This patch fixes the problem where the ethtool Supported link
modes list backplane interfaces on X722 devices for 10GbE with
SFP+ and Cortina retimer. This patch fixes the problem by setting
and using a flag for this particular device since the backplane
interface is only between the internal PHY and the retimer and it
should not be seen by the user as they cannot use it.
Without this patch, the user wrongly thinks that backplane interfaces
are supported on their device when they actually are not.

The PHY type value for unrecognized PHYs and cables was changed
based on firmware version number. Newer hardware use lower firmware
version numbers and this was causing some PHYs to be identified

Without this patch, newer card will incorrectly identify unknown

This change adds hardware type to the check for firmware version
so the PHY type is reported correctly.

On SPARC, writel() should not be used to write directly to memory
address but only to memory mapped I/O address otherwise it causes
data access exception.

Commit 147e81ec ("i40e: Test memory before ethtool alloc
succeeds") introduced a code that uses memory address to fake the HW
tail address and attempt to write to that address using writel()
causes kernel panic on SPARC. The issue is reproduced while changing
number of descriptors using ethtool.

This change resolves the panic by using HW read-only memory mapped
I/O register to fake HW tail address instead memory address.

This patch adds X553 flow control auto negotiation for fiber and
backplain.  To enable this new function pointers were added as well
as creating a function to dynamically set function pointer we can't
define only on MAC type.

This patch updates ixgbe_setup_phy_link_generic to set/unset
auto-negotiation for all speeds. This ensures that unsupported
speeds are unset. This is necessary since the PHY NVM may
advertise unsupported speeds.

This patch adds support to get the LED link active via the LEDCTL

(LED mode field = 0x0100) set then default LED link active returned.

X553 doesn't need all the initialization that X552 did for iXFI. This
patch will allow native SPI SFP+ to work with X553 devices.  Future
patches will add additional configuration as needed.
