The 5717 is a dual port chip that has a shared MDIO bus design. While
it is impossible for one function to interface with the wrong phy, that
function still needs to know which MDIO bus address to use when
interfacing with its own phy. This patch adds code to determine which
MDIO bus address to use.Signed-off-by: Matt Carlson

When RSS is enabled, the status block format changes slightly. The
"rx_jumbo_consumer", "reserved", and "rx_mini_consumer" members get
mapped to the other three rx return ring producer indexes. This patch
introduces a new per-interrupt member which identifies which location
in the status block a particular vector should look for return ring
updates.Signed-off-by: Matt Carlson

When multivector RSS is enabled, the first interrupt vector is only used
to report link interrupts and error conditions. This patch changes the

The 5717 assigns mailbox locations to interrupt vectors in a rather

Each interrupt vector has its own bit in the host coalescing register to
force that vector's status block to be updated and generate an
interrupt. This patch adds a member to the per-interrupt structure

These are full of unresolved problems, mainly that conversions don't
work 1-1 from hrtimers to tasklet_hrtimers because unlike hrtimers
tasklets can't be killed from softirq context.And when a qdisc gets reset, that's exactly what we need to do here.
We'll work this out in the net-next-2.6 tree and if warranted we'll
backport that work to -stable.This reverts the following 3 changesets:

After commit 2b85a34e911bf483c27cfdd124aeb1605145dc80
(net: No more expensive sock_hold()/sock_put() on each tx)
sk_free() frees socks conditionally and depends
on sk_wmem_alloc being set e.g. in sock_init_data(). But in some
cases sk_free() is called earlier, usually after other alloc errors.Fix is to move sk_wmem_alloc initialization from sock_init_data()
to sk_alloc() itself.Signed-off-by: Jarek Poplawski

struct net::ipv6.ip6_dst_ops is separatedly dynamically allocated,
but there is no fundamental reason for it. Embed it directly into
struct netns_ipv6.For that:
* move struct dst_ops into separate header to fix circular dependencies
I honestly tried not to, it's pretty impossible to do other way
* drop dynamical allocation, allocate together with netnsFor a change, remove struct dst_ops::dst_net, it's deducible
by using container_of() given dst_ops pointer.Signed-off-by: Alexey Dobriyan
