Enslaving a CAN or IEEE 802.15.4 device (e.g. vxcan, wpan0) to a
team master triggers a NULL pointer dereference because these
device types use different Layer 2 architectures from Ethernet and
the team driver never initializes their private mid-layer data
structures.
Reject ARPHRD_CAN, ARPHRD_IEEE802154, and ARPHRD_IEEE802154_MONITOR
devices in team_port_add(), mirroring the existing CAN check already
present in the bonding driver since commit 8ba68464e478 ("bonding:
refuse to enslave CAN devices").

Can we perhaps have a unified helper for the check?

How about adding a helper in include/linux/if_arp.h, similar to dev_is_mac_header_xmit()? Perhaps
something like dev_is_can_or_ieee802154()?
