When we need to shape traffic using low speeds, we need to
disable tso on network interface :

ethtool -K eth0.2240 tso off

It seems vlan interfaces miss the set_tso() ethtool method.

Before enabling TSO, we must check real device supports
TSO for VLAN-tagged packets and enables TSO.

Note that a TSO change on real device propagates TSO setting
on all vlans, even if admin selected a different TSO setting.

This patch makes IPV6 over IPv4 GRE tunnel propagate the transport
class field from the underlying IPV6 header to the IPV4 Type Of Service
field. Without the patch, all IPV6 packets in tunnel look the same to QoS.

This assumes that IPV6 transport class is exactly the same
as IPv4 TOS. Not sure if that is always the case?  Maybe need
to mask off some bits.

The mask and shift to get tclass is copied from ipv6/datagram.c

This patch relates to "[PATCH] gainfar.c : skb_over_panic
(kernel-2.6.32.15)"

While in 2.6.32.15 it actually fixed a bug here it merely cleans up
the previous attempts to fix the bug with a more coherent code.

Currently before queuing skb into the rx_recycle it is
"un-skb_reserve"-ed so when taken out in gfar_new_skb() it wont be
reserved twice.

This patch makes sure the alignment skb_reserve is done once, upon
allocating the skb and not when taken out of the rx_recycle
pool. Eliminating the need to undo anything before queue skb back to
the pool.

NOTE: This patch will compile and is fairly straight forward but I do
not have environment to test it as I did with the 2.6.32.15 fix.

There is a small possibility that a reader gets incorrect values on 32
bit arches. SNMP applications could catch incorrect counters when a
32bit high part is changed by another stats consumer/provider.

One way to solve this is to add a rtnl_link_stats64 param to all
ndo_get_stats64() methods, and also add such a parameter to
dev_get_stats().

Rule is that we are not allowed to use dev->stats64 as a temporary
storage for 64bit stats, but a caller provided area (usually on stack)

Old drivers (only providing get_stats() method) need no changes.

The bridge protocol lives dangerously by having incestuous relations
with the IP stack.  In this instance an abomination has been created
where a bogus IPCB area from a bridged packet leads to a crash in
the IP stack because it's interpreted as IP options.

This patch papers over the problem by clearing the IPCB area in that
particular spot.  To fix this properly we'd also need to parse any
IP options if present but I'm way too lazy for that.

bridge: Restore NULL check in br_mdb_ip_get

Somewhere along the line the NULL check in br_mdb_ip_get went
AWOL, causing crashes when we receive an IGMP packet with no
multicast table allocated.

This patch restores it and ensures all br_mdb_*_get functions
use it.

netif_vdbg() was originally defined as entirely equivalent to
netdev_vdbg(), but I assume that it was intended to take the same
parameters as netif_dbg() etc.  (Currently it is only used by the
sfc driver, in which I worked on that assumption.)

In commit a4ed89cb I changed the definition used when VERBOSE_DEBUG is
not defined, but I failed to notice that the definition used when
VERBOSE_DEBUG is defined was also not as I expected.  Change that to
match netif_dbg() as well.

Remove the call to tty_ldisc_flush() from the RESULT_NO_CARRIER
branch of isdn_tty_modem_result(), as already proposed in commit
00409bb0.
This avoids a "sleeping function called from invalid context" BUG
when the hardware driver calls the statcallb() callback with
command==ISDN_STAT_DHUP in atomic context, which in turn calls
isdn_tty_modem_result(RESULT_NO_CARRIER, ~), and from there,
tty_ldisc_flush() which may sleep.
