o Driver aborts the minidump collection operation when it finds
an unknown entry opcode. This patch skips unknown entry type
and resumes the minidump collection operation.
o Removed a comparision of collected dump size with expected dump size.
Size may differ when driver decides to skip an entry.

When more than one NIC physical functions are enabled on a port,
eSwitch on that port gets enabled automatically. Driver
need not explicitly enable the eSwitch.

Polling TX statuses too frequently has two negative effects. First is
randomly peek CPU usage, causing overall system functioning delays.
Second bad effect is that device is not able to fill TX statuses in
H/W register on some workloads and we get lot of timeouts like below:
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_txdone: Warning - Got TX status for an empty queue 2, dropping
This not only cause flood of messages in dmesg, but also bad throughput,
since rate scaling algorithm can not work optimally.
In the future, we should probably make polling interval be adjusted
automatically, but for now just increase values, this make mentioned
problems gone.

The regression was introduced in the following commit:
0967e01e8e713ed2982fb4eba8ba13794e9a6e89
"ath5k: make use of the new rate control API"
ath5k_tx_frame_completed saves the intended per-rate retry counts before
they are cleared by ieee80211_tx_info_clear_status, however at this
point the information in info->status.rates is incomplete.
This causes significant throughput degradation and excessive packet loss
on links where high bit rates don't work properly.
Move the copy from bf->rates a few lines up to ensure that the saved
retry counts are updated, and that they are really cleared in
info->status.rates after the call to ieee80211_tx_info_clear_status.

Since we set IEEE80211_HW_QUEUE_CONTROL, we can let
mac80211 do the queue assignement and don't need to
override its decisions.
While reassiging the same values is harmless of course,
it triggered a WARNING when iwlwifi and mac80211 came
to different conclusions. This happened when mac80211 set
IEEE80211_TX_CTL_SEND_AFTER_DTIM, but didn't route the
packet to the cab_queue because no stations were asleep.
iwlwifi should not override mac80211's decicions for
offchannel packets and packets to be sent after DTIM,
but it should override mac80211's decision for AMPDUs
since we have a special queue for them. So for AMPDU,
we still override info->hw_queue by the AMPDU queue.
This avoids:

The fw_rx_stats entry in debugfs was getting truncated because the
internal buffer used to hold the string was too short. The
calculation of the needed buffer size was rather bogus.
Simplify the calculation by multiplying the number of entries in the
entire structure by the size of each data line and adding the size of
the header lines.
Additionally, add the mac_id value, which was missing.

The firmware always expects the Coex Mode to be set.
Moreover, the firmware expects bit 0 is the valid bits to
be set all the times.
I misunderstood the API and didn't set these bits when
commands are sent to update the paramters of the Coex. As
a result, the firmware understood that the BT Coex was
disabled (Coex mode = 0) and ignored all the updates (valid
bit 0 clear).
Fix that.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
This is a batch of updates intended for the 3.13 stream...
The biggest item of interest in here is wcn36xx, the new mac80211
driver for Qualcomm WCN3660/WCN3680 hardware.
Regarding the mac80211 bits, Johannes says:
"We have an assortment of cleanups and new features, of which the
biggest one is probably the channel-switch support in IBSS. Nothing
else really stands out much."
On top of that, the ath9k and rt2x00 get a lot of update action from
Felix Fietkau and Gabor Juhos, respectively. There are a handful of
updates to other drivers here and there as well.
Please let me know if there are problems!

John W. Linville says:
====================
Please pull this batch of fixes intended for the 3.12 stream!
For the mac80211 bits, Johannes says:
"Jouni fixes a remain-on-channel vs. scan bug, and Felix fixes client TX
probing on VLANs."
And also:
"This time I have two fixes from Emmanuel for RF-kill issues, and fixed
two issues reported by Evan Huus and Thomas Lindroth respectively."
On top of those...
Avinash Patil adds a couple of mwifiex fixes to properly inform cfg80211
about some different types of disconnects, avoiding WARNINGs.
Mark Cave-Ayland corrects a pointer arithmetic problem in rtlwifi,
avoiding incorrect automatic gain calculations.
Solomon Peachy sends a cw1200 fix for locking around calls to
cw1200_irq_handler, addressing "lost interrupt" problems.
Please let me know if there are problems!

We used to schedule the refill work unconditionally after changing the
number of queues. This may lead an issue if the device is not
up. Since we only try to cancel the work in ndo_stop(), this may cause
the refill work still work after removing the device. Fix this by only
schedule the work when device is up.
The bug were introduce by commit 9b9cd8024a2882e896c65222aa421d461354e3f2.

We're trying to re-configure the affinity unconditionally in cpu hotplug
callback. This may lead the issue during resuming from s3/s4 since
- virt queues haven't been allocated at that time.
- it's unnecessary since thaw method will re-configure the affinity.
Fix this issue by checking the config_enable and do nothing is we're not ready.
The bug were introduced by commit 8de4b2f3ae90c8fc0f17eeaab87d5a951b66ee17
(virtio-net: reset virtqueue affinity when doing cpu hotplug).

If interrupts happen before napi_enable was called, the driver will not
work as expected. Network transmissions are impossible in this state.
This bug can be reproduced easily by restarting the network interface in
a loop. After some time any network transmissions on the network
interface will fail.
This patch fixes the bug by enabling napi before enabling the network
interface interrupts.

RPS support is kind of broken on bnx2x, because only non LRO packets
get proper rx queue information. This triggers reorders, as it seems
bnx2x like to generate a non LRO packet for segment including TCP PUSH
flag : (this might be pure coincidence, but all the reorders I've
seen involve segments with a PUSH)

We must call skb_record_rx_queue() to properly give to RPS (and more
generally for TX queue selection on forward path) the receive queue
information.
Similar fix is needed for skb_mark_napi_id(), but will be handled
in a separate patch to ease stable backports.

This patch adds code to handle SKB_GSO_TCPV6 skbs and construct appropriate
extra or prefix segments to pass the large packet to the frontend. New
xenstore flags, feature-gso-tcpv6 and feature-gso-tcpv6-prefix, are sampled
to determine if the frontend is capable of handling such packets.

There is no mechanism to insist that a guest always generates a packet
with good checksum (at least for IPv4) so we must handle checksum
offloading from the guest and hence should set NETIF_F_RXCSUM.

For performance of VM to VM traffic on a single host it is better to avoid
calculation of TCP/UDP checksum in the sending frontend. To allow this this
patch adds the code necessary to set up partial checksum for IPv6 packets
and xenstore flag feature-ipv6-csum-offload to advertise that fact to
frontends.
