WARNING: drivers/net/built-in.o(.data+0x24): Section mismatch in reference from
the variable dec_lance_tc_driver to the function .init.text:dec_lance_tc_probe()
The variable dec_lance_tc_driver references

Fixing this one results in a new mismatch:

The macros for the values of the bit field describing the four
different versions of statistics supported by different hardware
variants were being misused. Where the code was trying to test if the
hardware implements V3, it was actually testing whether it implements
any of V1, V2, or V3, causing the driver to report statistics that
don't really exist in the hardware, with bogus values.

There are still some LRO cards that cause GSO errors in tun,

Further, experience shows we might have more GSO bugs lurking.
See https://bugzilla.kernel.org/show_bug.cgi?id=16413

commit 6146b1a4da98377e4abddc91ba5856bef8f23f1e
Author: Jay Vosburgh <fubar@us.ibm.com>

bonding: Fix ALB mode to balance traffic on VLANs
the dev field in the RLB ARP packet handler was set to NULL to wildcard
and accommodate balancing VLANs on top of bonds.
This has the side-effect of the packet handler being called against
other, non RLB-enabled bonds, and a kernel oops results when it tries to
dereference rx_hashtbl in rlb_update_entry_from_arp(), which won't be
set for those bonds, e.g. active-backup.
With the __netif_receive_skb() changes from:
commit 1f3c8804acba841b5573b953f5560d2683d2db0d
Author: Andy Gospodarek <andy@greyhouse.net>
Date: Mon Dec 14 10:48:58 2009 +0000
bonding: allow arp_ip_targets on separate vlans to use arp validation
frames received on VLANs correctly make their way to the bond's handler,
so we no longer need to wildcard the device.
The oops can be reproduced by:
modprobe bonding
echo active-backup > /sys/class/net/bond0/bonding/mode
echo 100 > /sys/class/net/bond0/bonding/miimon
ifconfig bond0 xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx
echo +eth0 > /sys/class/net/bond0/bonding/slaves
echo +eth1 > /sys/class/net/bond0/bonding/slaves
echo +bond1 > /sys/class/net/bonding_masters
echo balance-alb > /sys/class/net/bond1/bonding/mode
echo 100 > /sys/class/net/bond1/bonding/miimon
ifconfig bond1 xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx
echo +eth2 > /sys/class/net/bond1/bonding/slaves
echo +eth3 > /sys/class/net/bond1/bonding/slaves
Pass some traffic on bond0. Boom.
[ Tested, behaves as advertised. I do not believe a test of the bonding
mode is necessary, as there is no race between the packet handler and
the bonding mode changing (the mode can only change when the device is
closed). Also updated the log message to include the reproduction and
full commit ids. -J ]

Both of_bus_type and of_platform_bus_type are just #define aliases
for the platform bus. This patch removes all references to them and
switches to the of_register_platform_driver()/of_unregister_platform_driver()
API for registering.
Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim. At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.

gcc complains about the firmware loading:
iwl-agn.c: In function ‘iwlagn_load_firmware’:
iwl-agn.c:1860: warning: ‘tlv_len’ may be used uninitialized in this function
iwl-agn.c:1861: warning: ‘tlv_type’ may be used uninitialized in this function
iwl-agn.c:1862: warning: ‘tlv_data’ may be used uninitialized in this function
This is almost correct but we do do break out of the TLV
parsing loop when setting ret. However, the code is hard
to follow, and clearly even the compiler is having issues
with it too.
Additionally, however, the current code is wrong. If there
is a TLV length check error, the code will report
invalid TLV after parsing: ...
because "len" will still be non-zero as we broke out of
the loop.
So to remove the warning and fix that issue, make the code
easier to read by doing length checking with an error label.
As a result, we can completely remove the "ret" variable.
Also, while at it, remove the "fixed_tlv_size" variable
since each TLV type has its own specified length, it just
happens that we have only variable length, flags (0 length)
and u32 TLVs right now. It should still be checked with more
explicit length checks to make it easier to understand.

When copying VLAN information to or removing from a slave
during slave addition or removal, the bonding code currently holds
the bond->lock for write to prevent concurrent modification of the
vlan_list / vlgrp.
This is unnecessary, as all of these operations occur under
RTNL. Holding the bond->lock also caused might_sleep issues for
some drivers' ndo_vlan_* functions. This patch removes the extra
locking.

After commit ad1afb00393915a51c21b1ae8704562bf036855f
("vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)")
it is now regular practice for a VLAN "add vid" for VLAN 0 to
arrive prior to any VLAN registration or creation of a vlan_group.
This patch updates the bonding code that tests for the presence
of VLANs configured above bonding. The new logic tests for bond->vlgrp
to determine if a registration has occured, instead of testing that
bonding's internal vlan_list is empty.
The old code would panic when vlan_list was not empty, but
vlgrp was still NULL (because only an "add vid" for VLAN 0 had occured).
Bonding still adds VLAN 0 to its internal list so that 802.1p
frames are handled correctly on transmit when non-VLAN accelerated
slaves are members of the bond. The test against bond->vlan_list
remains in bond_dev_queue_xmit for this reason.
Modification to the bond->vlgrp now occurs under lock (in
addition to RTNL), because not all inspections of it occur under RTNL.
Additionally, because 8021q will never issue a "kill vid" for
VLAN 0, there is now logic in bond_uninit to release any remaining
entries from vlan_list.

Mark Wagner reported OOM symptoms when sending UDP traffic over
a macvtap link to a kvm receiver.
This appears to be caused by the fact that macvtap packet queues
are unlimited in length. This means that if the receiver can't
keep up with the rate of flow, then we will hit OOM. Of course
it gets worse if the OOM killer then decides to kill the receiver.
This patch imposes a cap on the packet queue length, in the same
way as the tuntap driver, using the device TX queue length.
Please note that macvtap currently has no way of giving congestion
notification, that means the software device TX queue cannot be
used and packets will always be dropped once the macvtap driver
queue fills up.
This shouldn't be a great problem for the scenario where macvtap
is used to feed a kvm receiver, as the traffic is most likely
external in origin so congestion notification can't be applied
anyway.
Of course, if anybody decides to complain about guest-to-guest
UDP packet loss down the track, then we may have to revisit this.
Incidentally, this patch also fixes a real memory leak when
macvtap_get_queue fails.
Chris Wright noticed that for this patch to work, we need a
non-zero TX queue length. This patch includes his work to change
the default macvtap TX queue length to 500.
