From bd9d55929df54b67708460d7eda84a7d7924009d Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 28 Feb 2014 15:46:49 -0800 Subject: [PATCH] ixgbevf: fix skb->pkt_type checks 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, it is still potentially confusing. This bogus check was introduced in commit 815cccbf ("ixgbe: add setlink, getlink support to ixgbe and ixgbevf").
