mac80211 documentation says, the ieee80211_ops.start callback "must turn on frame reception (for possibly enabled monitor interfaces.)". If not a single monitor interface does not receive data frames. Similarly we should not change the data reception based on the association state.

2016-02-18Merge branch '40GbE' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-02-18 This series contains updates to i40e and i40evf only. Alex Duyck provides all the patches in the series to update and fix the drivers. Fixed the driver to drop the outer checksum offload on UDP tunnels, since the issue is that the upper levels of the stack never requested such an offload and it results in possible errors. Updates the TSO function to just use u64 values, so we do not have to end up casting u32 values. In the TSO path, factored out the L4 header offsets allowing us to ignore the L4 header offsets when dealing with the L3 checksum and length update. Consolidates all of the spots where we were updating either the TCP or IP checksums in the TSO and checksum path into the TSO function. Fixed two issues by adding support for IPv4 encapsulated in IPv6, first issue was the fact that iphdr(skb)->protocol was being used to test for the outer transport protocol which breaks IPv6 support. The second was that we cleared the flag for v4 going to v6, but we did not take care of txflags going the other way. Added support for IPv6 extension headers in setting up the Tx checksum. Added exception handling to the Tx checksum path so that we can handle cases of TSO where the frame is bad, or Tx checksum where we did not recognize a protocol. Fixed a number of issues to make certain that we are using the correct protocols when parsing both the inner and outer headers of a frame that is mixed between IPv4 and IPv6 for inner and outer. Updated the feature flags to reflect the newly enabled/added features. Sorry, no witty patch descriptions this time around, probably should let Mitch help in writing patch descriptions for Alex. :-) ==================== Signed-off-by: David S.

2016-02-18i40evf: Update feature flags to reflect newly enabled featuresAlexander Duyck
Recent changes should have enabled support for IPv6 based tunnels and support for TSO with outer UDP checksums. As such we can update the feature flags to reflect that. In addition we can clean-up the flags that aren't needed such as SCTP and RXCSUM since having the bits there doesn't add any value. I also found one spot where we were setting the same flag twice. It looks like it was probably a git merge error that resulted in the line being duplicated. As such I have dropped it in this patch.

2016-02-18i40e: Do not drop support for IPv6 VXLAN or GENEVE tunnelsAlexander Duyck
All of the documentation in the datasheets for the XL710 do not call out any reason to exclude support for IPv6 based tunnels. As such I am dropping the code that was excluding these tunnel types from having their port numbers recognized. This way we can take advantage of things such as checksum offload for inner headers over IPv6 based VXLAN or GENEVE tunnels.

2016-02-18qed: Lay infrastructure for vlan filtering offloadYuval Mintz
Today, interfaces are working in vlan-promisc mode; But once vlan filtering offloaded would be supported, we'll need a method to control it directly [e.g., when setting device to PROMISC, or when running out of vlan credits].

2016-02-18net: Optimize local checksum offloadAlexander Duyck
This patch takes advantage of several assumptions we can make about the headers of the frame in order to reduce overall processing overhead for computing the outer header checksum. First we can assume the entire header is in the region pointed to by skb->head as this is what csum_start is based on. Second, as a result of our first assumption, we can just call csum_partial instead of making a call to skb_checksum which would end up having to configure things so that we could walk through the frags list.

2016-02-18Merge branch 'iptunnel-pkt-scrub-consolidate'David S. Miller
Jiri Benc says: ==================== iptunnel: scrub packet in iptunnel_pull_header As every IP tunnel has to scrub skb on decapsulation, iptunnel_pull_header tried to do that and open coded part of skb_scrub_packet. Various tunneling protocols (VXLAN, Geneve) then called full skb_scrub_packet on their own, duplicating part of the scrubbing already done. Consolidate the code, calling skb_scrub_packet from iptunnel_pull_header. This will allow additional cleanups in VXLAN code, as the packet is scrubbed early during rx processing after this patchset and VXLAN can start filling out skb fields earlier.
