Jesse Brandeburg a80483d372 e1000e: fix packet corruption and tx hang during NFSv2
when receiving a particular type of NFS v2 UDP traffic, the hardware could
DMA some bad data and then hang, possibly corrupting memory.

Disable the NFS parsing in this hardware, verified to fix the bug.

Sridhar Samudrala 8e1e8a4779 net: Fix IPv6 GSO type checks in Intel ethernet drivers
Found this problem when testing IPv6 from a KVM guest to a remote
host via e1000e device on the host.
The following patch fixes the check for IPv6 GSO packet in Intel
ethernet drivers to use skb_is_gso_v6(). SKB_GSO_DODGY is also set
when packets are forwarded from a guest.

Jesse Brandeburg 9926146b15 e1000/e1000e: don't use small hardware rx buffers
When testing the "e1000: enhance frame fragment detection" (and e1000e)
patches we found some bugs with reducing the MTU size.  The 1024 byte
descriptor used with the 1000 mtu test also (re) introduced the
(originally) reported bug, and causes us to need the e1000_clean_tx_irq
"enhance frame fragment detection" fix.

So what has occured here is that 2.6.32 is only vulnerable for mtu <
1500 due to the jumbo specific routines in both e1000 and e1000e.
So, 2.6.32 needs the 2kB buffer len fix for those smaller MTUs, but
is not vulnerable to the original issue reported.  It has been pointed
out that this vulnerability needs to be patched in older kernels that
don't have the e1000 jumbo routine.  Without the jumbo routines, we
need the "enhance frame fragment detection" fix the e1000, old
e1000e is only vulnerable for < 1500 mtu, and needs a similar
fix.  We split the patches up to provide easy backport paths.

There is only a slight bit of extra code when this fix and the
original "enhance frame fragment detection" fixes are applied, so
please apply both, even though it is a bit of overkill.

Jesse Brandeburg b94b502896 e1000e: enhance frame fragment detection
Originally patched by Neil Horman <nhorman@tuxdriver.com>

e1000e could with a jumbo frame enabled interface, and packet split disabled,
receive a packet that would overflow a single rx buffer.  While in practice
very hard to craft a packet that could abuse this, it is possible.

this is related to CVE-2009-4538

A previous 82577 workaround that set the MDIO access speed to slow mode for
every PHY register read/write when the cable is unplugged should instead
set the access mode to always be slow before any PHY register access.
Since the mode bit gets cleared when the PHY is reset, set the mode after
every PHY reset.

The Tx unit hang detection code in e1000e detects other hangs caused by
hardware components (e.g. Rx, DMA units), but it is not possible to detect
exactly which component is hung so it has always assumed a Tx unit hang.
When dumping a message to the system log because of a hang, this patch adds
more data to help narrow the cause of the issue and makes the message
non-Tx-specific.  Because this new code reads PHY registers which can
sleep, move it off to a workqueue.  This and all previously existing work
tasks in the driver are now cancelled when the driver is removed.

There is no reason to save the register contents so the temp variable can
be removed.

Bruce Allan 564ea9bba1 e1000e: set bools to true/false instead of 1/0
Set booleans to 'true' or 'false' to make it clear it is a boolean.  Also
change instances of TRUE/FALSE in comments to lowercase true/false.
