skb->pkt_type is not a bitmask, but contains only value at a time from the range defined in include/uapi/linux/if_packet.h.
Checking it like if it was a bitmask of values would also cause PACKET_OTHERHOST, PACKET_LOOPBACK and PACKET_FASTROUTE to be matched by this check since their lower 2 bits are also set, although that does not fix a real bug due to how the checks are used, it is still potentially confusing. This bogus check was introduced in commit 815cccbf ("ixgbe: add setlink, getlink support to ixgbe and ixgbevf").
