Mandeep Baines 0bdfea8ba8 forcedeth: Improve stats counters
Rx byte count was off; instead use the hardware's count.  Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.

- The count of transmitted packets reported by the forcedeth driver
  reports pre-TSO (TCP Segmentation Offload) packet counts and not the
  count of the number of packets sent on the wire. This change fixes
  the forcedeth driver to report the correct count. Fixed the code by
  copying the count stored in the NIC H/W to the value reported by the
  driver.

- Count rx_drop_frame errors as rx_fifo_errors:
  We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
  for too long.  Normally, rx_fifo_errors would be counted in this case.
  The rx_drop_frame error count is private to forcedeth and is not
  reported by ifconfig or sysfs.  The rx_fifo_errors count is currently
  unused in the forcedeth driver.  It is reported by ifconfig as overruns.
  This change reports rx_drop_frame errors as rx_fifo_errors.

david decotigny 4687f3f364 forcedeth: remove unneeded stats updates
Function ndo_get_stats() updates most of the stats from hardware
registers, making the manual updates un-needed. This change removes
these manual updates. Main exception is rx_missed_errors which needs
manual update.

Another exception is rx_packets, still updated manually in this commit
to make sure this patch doesn't change behavior of driver. This will
be addressed by a future patch.

david decotigny f9c4082df5 forcedeth: fix race when unloading module
When forcedeth module is unloaded, there exists a path that can lead
to mod_timer() after del_timer_sync(), causing an oops. This patch
short-circuits this unneeded path, which originates in
nv_get_ethtool_stats().

Tested:

stephen hemminger 27d240fdae sky2: fix regression on Yukon Optima
Changes to support other Optima types, introduced an accidental
regression that caused 88E8059 to come up in 10Mbit/sec.

The Yukon Optima supports a reverse auto-negotiation feature that
was incorrectly setup, and not needed. The feature could be used to
allow wake-on-lan at higher speeds. But doing it correctly would require
other changes to initialization.

stephen hemminger 729e72a109 macvlan: receive multicast with local address
When implementing VRRP v2 using macvlan several problems were
discovered.  VRRP is weird in that all routers participating
in a redundant group use the same virtual MAC address.
Macvlan is a natural driver to use for this but it doesn't
work.  The problem is that packets with a macvlan device's
source address are not received.

The problem is actually a regression that date back almost 2 years now.
The original problems started with:

commit 618e1b7482
Author: Arnd Bergmann <arnd@arndb.de>
Date:   Thu Nov 26 06:07:10 2009 +0000

    macvlan: implement bridge, VEPA and private mode

This patches restores the original 2.6.32 behavior. Allowing multicast
packets received with the VRRP source address to be received.

Matt Carlson 5b19062419 tg3: Eliminate timer race with reset_task
During shutdown, it is impossible to reliably disable the timer and
reset_task threads.  Each thread can schedule the other, which leads to
shutdown code that chases its tail.

To fix the problem, this patch removes the ability of tg3_reset_task to
schedule a new timer thread.  To support this change, tg3_timer no
longer terminates itself, but rather goes into a polling mode.

Matt Carlson db21997379 tg3: Schedule at most one tg3_reset_task run
It is possible for multiple threads in the tg3 driver to each attempt to
schedule a run of tg3_reset_task().  The multiple tg3_reset_task
executions could all wind up on the same queue (and execute serially) or
wind up on the queues of another processor (which could execute in
parallel).  Either scenario is not what was truly desired.

This patch adds a new flag, TG3_FLAG_RESET_TASK_PENDING, and uses it to
determine whether or not to schedule another run of tg3_reset_task().
With the new flag comes two new functions to facilitate scheduling and
descheduling of tg3_reset_task().

Returning the max traffic classes on get requests simplifies
user space configurations because applications will know
explicitly how many traffic classes can be used.

Typical switch implementations use 2 or 3 traffic classes
so this not seen often today. And user space can learn
the number of traffic classes by return codes but this
allows user space to configure ixgbe correctly at the
start.

Emil Tantilov 331bcf45fe ixgbe: fix reading of the buffer returned by the firmware
This patch fixes some issues found in the buffer read portion of
ixgbe_host_interface_command()

- use `bi` as the buffer index counter instead of `i`
- add conversion to native cpu byte ordering on register read
- fix conversion from bytes to dword
- use dword_len instead of buf_len when reading the register

Emil Tantilov 93d3ce8faf ixgbe: fix disabling of Tx laser at probe
register_netdev() calls ndo_set_features() which may result in HW reset
which in turn will bring the laser back up.

This patch moves ixgbe_laser_tx_disable() below register_netdev()
in ixgbe_probe() to make sure laser is shut off on load.

Emil Tantilov 232ef6bc45 ixgbe: Fix link issues caused by a reset while interface is down
Interface fails to obtain link on 82599 SFP in the following scenario:

1. Set advertised speed to GB:
ethtool -s eth0 advertise 0x20

2. Bring interface down
ip link set eth0 down

3. Issue any command that leads to a reset:
ethtool -t eth0

4. Bring link back up:
ip link set eth0 up

Following patch makes sure that the driver flaps the Tx laser every time
ixgbe_start_hw() is called, and not only when the speed is set.

Jesse Brandeburg 243559f436 e100: make sure vlan support isn't advertised on old adapters
e100 parts don't support vlan offload but they generally do
allow use of vlans in higher software layers via the 8021q module.
That said, there are a couple of really old revisions of e100
hardware that don't even allow the longer frame sizes
required for vlan use with standard MTU.

Use the VLAN_CHALLENGED flag to prevent vlan binding to these
devices.

Andres Salomon 3209e061ad libertas: ensure we clean up a scan request properly
Commit 2e30168b ("libertas: terminate scan when stopping interface")
adds cleanup code to lbs_eth_stop to call cfg80211_scan_done if there's
an outstanding cfg80211_scan_request.  However, it assumes that the
scan request was allocated via the cfg80211 stack.  Libertas has
its own internal allocation method, kept track of with
priv->internal_scan.  This doesn't set scan_req->wiphy, amongst other
things, which results in hitting a BUG() when we call cfg80211_scan_done
on the request.

This provides a function to take care of the low-level scan_req cleanup
details.  We simply call that to deal with finishing up scan requests.

The bug we were hitting was:

[  964.321495] kernel BUG at net/wireless/core.h:87!
