commit d5a9e24afb4ab38110ebb777588ea0bd0eacbd0a
net: Allow RX queue selection to seed TX queue hashing.
The idea is that drivers which implement multiqueue RX
pre-seed the SKB by recording the RX queue selected by
the hardware.
If such a seed is found on TX, we'll use that to select
the outgoing TX queue.
This helps get more consistent load balancing on router
and firewall loads.

commit 9d21493b4beb8f918ba248032fefa393074a5e2b
net: tx scalability works : trans_start
struct net_device trans_start field is a hot spot on SMP and high
performance
devices, particularly multi queues ones, because every transmitter
dirties
it. Is main use is tx watchdog and bonding alive checks.
But as most devices dont use NETIF_F_LLTX, we have to lock
a netdev_queue before calling their ndo_start_xmit(). So it makes
sense to move trans_start from net_device to netdev_queue. Its update
will occur on a already present (and in exclusive state) cache line, for
free.
We can do this transition smoothly. An old driver continue to
update dev->trans_start, while an updated one updates txq->trans_start.
Further patches could also put tx_bytes/tx_packets counters in
netdev_queue to avoid dirtying dev->stats (vlan device comes to mind)

commit 042a53a9e437feaf2230dd2cadcecfae9c7bfe05
net: skb_shared_info optimization
skb_dma_unmap() is quite expensive for small packets,
because we use two different cache lines from skb_shared_info.
One to access nr_frags, one to access dma_maps[0]
Instead of dma_maps being an array of MAX_SKB_FRAGS + 1 elements,
let dma_head alone in a new dma_head field, close to nr_frags,
to reduce cache lines misses.
Tested on my dev machine (bnx2 & tg3 adapters), nice speedup !

commit 31278e71471399beaff9280737e52b47db4dc345
net: group address list and its count
This patch is inspired by patch recently posted by Johannes Berg.
Basically what
my patch does is to group list and a count of addresses into newly
introduced
structure netdev_hw_addr_list. This brings us two benefits:
1) struct net_device becames a bit nicer.
2) in the future there will be a possibility to operate with lists
independently
on netdevices (with exporting right functions).
I wanted to introduce this patch before I'll post a multicast lists
conversion.

commit 0c27922e4933ceb86644f4a9b1af212ffe5aad75
net: dev_addr_init() fix
commit f001fde5eadd915f4858d22ed70d7040f48767cf
(net: introduce a list of device addresses dev_addr_list (v6))
added one regression Vegard Nossum found in its testings.
With kmemcheck help, Vegard found some uninitialized memory
was read and reported to user, potentialy leaking kernel data.
( thread can be found on http://lkml.org/lkml/2009/5/30/177 )
dev_addr_init() incorrectly uses sizeof() operator. We were
initializing one byte instead of MAX_ADDR_LEN bytes.

commit ccffad25b5136958d4769ed6de5e87992dd9c65c
net: convert unicast addr list
This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).
I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.
The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.

commit f001fde5eadd915f4858d22ed70d7040f48767cf
net: introduce a list of device addresses dev_addr_list (v6)
v5 -> v6 (current):
-removed so far unused static functions
-corrected dev_addr_del_multiple to call del instead of add
v4 -> v5:
-added device address type (suggested by davem)
-removed refcounting (better to have simplier code then safe
potentially few
bytes)
v3 -> v4:
-changed kzalloc to kmalloc in __hw_addr_add_ii()
-ASSERT_RTNL() avoided in dev_addr_flush() and dev_addr_init()
v2 -> v3:
-removed unnecessary rcu read locking
-moved dev_addr_flush() calling to ensure no null dereference of
dev_addr
v1 -> v2:
-added forgotten ASSERT_RTNL to dev_addr_init and dev_addr_flush
-removed unnecessary rcu_read locking in dev_addr_init
-use compare_ether_addr_64bits instead of compare_ether_addr
-use L1_CACHE_BYTES as size for allocating struct netdev_hw_addr
-use call_rcu instead of rcu_synchronize
-moved is_etherdev_addr into __KERNEL__ ifdef
This patch introduces a new list in struct net_device and brings a set
of
functions to handle the work with device address list. The list is a
replacement
for the original dev_addr field and because in some situations there is
need to
carry several device addresses with the net device. To be backward
compatible,
dev_addr is made to point to the first member of the list so original
drivers
sees no difference.

commit 260d703adc5f275e3ba7ddff6e2e0217bc613b35
PCI: support for PCI Express fundamental reset
This is the first of three patches that implement a bit field that PCI
Express device drivers can use to indicate they need a fundamental reset
during error recovery.
By default, the EEH framework on powerpc does what's known as a "hot
reset" during recovery of a PCI Express device. We've found a case
where the device needs a "fundamental reset" to recover properly. The
current PCI error recovery and EEH frameworks do not support this
distinction.
The attached patch (courtesy of Richard Lary) adds a bit field to
pci_dev that indicates whether the device requires a fundamental reset
during recovery.
These patches supersede the previously submitted patch that implemented
a fundamental reset bit field.

netdev: change transmit to limited range type

some drivers got confused and returned errno's or other values.
This changes the definition so that this can be caught at compile time.
