Hi John,
In commit 815cccbf ("ixgbe: add setlink, getlink support to ixgbe and
ixgbevf") this line was added:
+ if ((skb->pkt_type & (PACKET_BROADCAST | PACKET_MULTICAST)) &&
+ !(compare_ether_addr(adapter->netdev->dev_addr,
+ eth_hdr(skb)->h_source))) {
This looks suspicious to me since skb->pkt_type is not a bitmask, but
holds only one value at a time, and with this check you would also
match any value which has the lower two bits set, so PACKET_OTHERHOST,
PACKET_LOOPBACK and PACKET_FASTROUTE are also matching the first part
of the check.
