This fix solves an issue occurring while calling i40e_led_set function
from the driver with "blink" parameter set as TRUE. This call resulted
in Activity LED blinking instead of Link LED, which may lead to errors
in physically identifying the port, since Activity LED may be blinking
for different reasons as well.

Since commit 96a39aed ("i40e: Acquire NVM lock before
reads on all devices") we've used the NVM lock
to synchronize NVM reads even on devices which don't strictly
need the lock.

Doing so can cause a regression on older firmware prior to 1.5,
especially when downgrading the firmware.

Fix this by only grabbing the lock if we're running on an X722
device (which requires the lock as it uses the AdminQ to read
the NVM), or if we're currently running 1.5 or newer firmware.

This patch enables tc-flower based hardware offloads. tc flower
filter provided by the kernel is configured as driver specific
cloud filter. The patch implements functions and admin queue
commands needed to support cloud filters in the driver and
adds cloud filters to configure these tc-flower filters.

The classification function of the filter is to direct matched
packets to a traffic class. The hardware traffic class is set
based on the the classid reserved in the range :ffe0 - :ffef.

Match Dst MAC and route to TC0:
  prio 1 flower dst_mac 3c:fd:fe:a0:d6:70 skip_sw\
  hw_tc 1

Match Dst IPv4,Dst Port and route to TC1:
  prio 2 flower dst_ip 192.168.3.5/32\
  ip_proto udp dst_port 25 skip_sw\
  hw_tc 2

Match Dst IPv6,Dst Port and route to TC1:
  prio 3 flower dst_ip fe8::200:1\
  ip_proto udp dst_port 66 skip_sw\
  hw_tc 2

Delete tc flower filter:
Example:

Flow Director Sideband is disabled while configuring cloud filters
via tc-flower and until any cloud filter exists.

Unsupported matches when cloud filters are added using enhanced
big buffer cloud filter mode of underlying switch include:
1. source port and source IP
2. Combined MAC address and IP fields.
3. Not specifying L4 port

These filter matches can however be used to redirect traffic to
the main VSI (tc 0) which does not require the enhanced big buffer
cloud filter support.

Increase the size of the prefix buffer so that it can hold enough
characters for every possible input. Although 20 is enough for all
expected inputs, it is possible for the values to be larger than
expected, resulting in a possibly truncated string. Additionally, lets
use sizeof(prefix) in order to ensure we use the correct size if we need
to change the array length in the future.

New versions of GCC starting at 7 now include warnings to prevent
truncation unless you handle the return code. At most 27 bytes can be
written here, so lets just increase the buffer size even if for all
expected hw->bus.* values we only needed 20.

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.
