Add classful DRR scheduler as a more flexible replacement for SFQ.
The main difference to the algorithm described in "Efficient Fair Queueing
using Deficit Round Robin" is that this implementation doesn't drop packets
from the longest queue on overrun because its classful and limits are
handled by each individual child qdisc.Signed-off-by: Patrick McHardy

A netlink attribute padding of zero triggers this sparse warning:
include/linux/netlink.h:245:8: warning: memset with byte count of 0
Avoid the memset when the size parameter is constant and requires no padding.

This patch is to kill directly reference of netdev->priv too.
Because the private data should be allocated in DMA area, alloc_etherdev()
can't satisfy this needs.
Use netdev->ml_priv to point to lance_private.Signed-off-by: Wang Chen

Currently, if multiple unicast addresses are programmed into a
mv643xx_eth interface, the core networking will resort to enabling
promiscuous mode on the interface, as mv643xx_eth does not implement
->set_rx_mode().This patch switches mv643xx_eth over from ->set_multicast_list()
to ->set_rx_mode(), and implements support for secondary unicast
addresses. The hardware can handle multiple unicast addresses as
long as their first 11 nibbles are the same (i.e. are of the form
xx:xx:xx:xx:xx:xy where the x part is the same for all addresses), so
if that is the case, we use that mode. If it's not the case, we enable
unicast promiscuous mode in the hardware, which is slightly better than
enabling promiscuous mode for multicasts as well, which is what would
happen before.While we are at it, change the programming sequence so that we
don't clear all filter bits first, so we don't lose all incoming
packets while the filter is being reprogrammed.Signed-off-by: Lennert Buytenhek

Since txq_alloc_desc_index() is a very simple function, and since
descriptor ring index handling for transmit reclaim, receive
processing and receive refill is already handled inline as well,
inline txq_alloc_desc_index() into its two call sites.Signed-off-by: Lennert Buytenhek

The mv643xx_eth driver uses the rdl()/wrl() macros to read and
write hardware registers. Per-port registers are accessed in the
following way:#define PORT_STATUS(p) (0x0444 + ((p) << 10))
[...]
static inline u32 rdl(struct mv643xx_eth_private *mp, int offset)
{
return readl(mp->shared->base + offset);
}[...]
port_status = rdl(mp, PORT_STATUS(mp->port_num));
By giving the per-port 'struct mv643xx_eth_private' its own
'void __iomem *base' pointer that points to the per-port register
area, we can get rid of both the double indirection and the << 10
that is done for every per-port register access -- this patch does
that.Signed-off-by: Lennert Buytenhek

Since all the memory, which pointed by netdev->priv, are allocated in

1. When alloc_etherdev(), no memory be allocated to netdev->priv.
2. And it's need to get a whole page for priv.For these reasons, use netdev->ml_priv to point to the page is the
best method to convert directly reference of netdev->priv.Signed-off-by: Wang Chen

SKF_AD_NLATTR allows us to find the first matching attribute in a
stream of netlink attributes from one offset to the end of the
netlink message. This is not suitable to look for a specific
matching inside a set of nested attributes.For example, in ctnetlink messages, if we look for the CTA_V6_SRC
attribute in a message that talks about an IPv4 connection,
SKF_AD_NLATTR returns the offset of CTA_STATUS which has the same
value of CTA_V6_SRC but outside the nest. To differenciate
CTA_STATUS and CTA_V6_SRC, we would have to make assumptions on the
size of the attribute and the usual offset, resulting in horrible
BSF code.This patch adds SKF_AD_NLATTR_NEST, which is a variant of
SKF_AD_NLATTR, that looks for an attribute inside the limits of
a nested attributes, but not further.This patch validates that we have enough room to look for the
nested attributes - based on a suggestion from Patrick McHardy.Signed-off-by: Pablo Neira Ayuso

When suspending the device the ring structure is freed which causes it to
loose track of the count. To resolve this we need to move the ring count
outside of the ring structure and store it in the adapter struct.In addition to resolving the suspend/resume issue this patch also addresses
issues seen in the event of memory allocation errors causing uneven ring
sizes on multiple queues.Signed-off-by: Alexander Duyck

This patch prepares RCU migration of listening_hash table for
TCP/DCCP protocols.listening_hash table being small (32 slots per protocol), we add
a spinlock for each slot, instead of a single rwlock for whole table.This should reduce hold time of readers, and writers concurrency.
