The BCM43341B has the default MAC address 43:34:1B:00:1F:AC if none
is given. This address was found when enabling Bluetooth on multiple
Intel Edison modules. It also contains the sequence 43341B, the name
the chip identifies itself as. Using the same BD_ADDR is problematic
when having multiple Intel Edison modules in each others range.
The default address also has the LAA (locally administered address)
bit set which prevents a BNEP device from being created, needed for
BT tethering.
Add this to the list of black listed default MAC addresses and let
the user configure a valid one using f.i.

Stanislav Fomichev says:
====================
Currently, when eth_get_headlen calls flow dissector, it doesn't pass any
skb. Because we use passed skb to lookup associated networking namespace
to find whether we have a BPF program attached or not, we always use
C-based flow dissector in this case.
The goal of this patch series is to add new networking namespace argument
to the eth_get_headlen and make BPF flow dissector programs be able to
work in the skb-less case.
The series goes like this:
* use new kernel context (struct bpf_flow_dissector) for flow dissector
programs; this makes it easy to distinguish between skb and no-skb
case and supports calling BPF flow dissector on a chunk of raw data
* convert BPF_PROG_TEST_RUN to use raw data
* plumb network namespace into __skb_flow_dissect from all callers
* handle no-skb case in __skb_flow_dissect
* update eth_get_headlen to include net namespace argument and
convert all existing users
* add selftest to make sure bpf_skb_load_bytes is not allowed in
the no-skb mode
* extend test_progs to exercise skb-less flow dissection as well
* stop adjusting nhoff/thoff by ETH_HLEN in BPF_PROG_TEST_RUN
v6:
* more suggestions by Alexei:
* eth_get_headlen now takes net dev, not net namespace
* test skb-less case via tun eth_get_headlen
* fix return errors in bpf_flow_load
* don't adjust nhoff/thoff by ETH_HLEN
v5:
* API changes have been submitted via bpf/stable tree
v4:
* prohibit access to vlan fields as well (otherwise, inconsistent
between skb/skb-less cases)
* drop extra unneeded check for skb->vlan_present in bpf_flow.c
v3:
* new kernel xdp_buff-like context per Alexei suggestion
* drop skb_net helper
* properly clamp flow_keys->nhoff
v2:
* moved temporary skb from stack into percpu (avoids memset of ~200 bytes
per packet)
* tightened down access to __sk_buff fields from flow dissector programs to
avoid touching shinfo (whitelist only relevant fields)
* addressed suggestions from Willem

Now that we have bpf_flow_dissect which can work on raw data,
use it when doing BPF_PROG_TEST_RUN for flow dissector.
Simplifies bpf_prog_test_run_flow_dissector and allows us to
test no-skb mode.
Note, that previously, with bpf_flow_dissect_skb we used to call
eth_type_trans which pulled L2 (ETH_HLEN) header and we explicitly called
skb_reset_network_header. That means flow_keys->nhoff would be
initialized to 0 (skb_network_offset) in init_flow_keys.
Now we call bpf_flow_dissect with nhoff set to ETH_HLEN and need
to undo it once the dissection is done to preserve the existing behavior.

flow dissector BPF program is allowed to access and an optional
pointer to real skb. Real skb is used only in bpf_skb_load_bytes

There are quite many differences between MT766[3,8]S and standard

MT766[3,8]S have its own SDIO registers layout, definition, SDIO packet

the device initialization and low power control and so on.
Currently, there are many independent programming sequences from the
transport which are exactly the same as the ones in btusb.c about MediaTek

mlxsw: Shared buffer improvements
This patchset includes two improvements with regards to shared buffer
configuration in mlxsw.
The first part of this patchset forbids the user from performing illegal
shared buffer configuration that can result in unnecessary packet loss.
In order to better communicate these configuration failures to the user,
extack is propagated from devlink towards drivers. This is done in
patches #1-#8.
The second part of the patchset deals with the shared buffer
configuration of the CPU port. When a packet is trapped by the device,
it is sent across the PCI bus to the attached host CPU. From the
device's perspective, it is as if the packet is transmitted through the
CPU port.
While testing traffic directed at the CPU it became apparent that for
certain packet sizes and certain burst sizes, the current shared buffer
configuration of the CPU port is inadequate and results in packet drops.
The configuration is adjusted by patches #9-#14 that create two new pools
- ingress & egress - which are dedicated for CPU traffic.

Use the new ingress pool that was added in the previous patch for
control packets (e.g., STP, LACP) that are trapped to the CPU.
The previous management pool is no longer necessary and therefore its
size is set to 0.
The maximum quota for traffic towards the CPU is increased to 50% of the
free space in the new ingress pool and therefore the reserved space is
reduced by half, to 10KB - in both the shared and headroom buffer. This
allows for more efficient utilization of the shared buffer as reserved
space cannot be used for other purposes.
