TI DaVinci EMAC: delay DaVinci EMAC initialization

On TI's DA850/OMAP-L138 EVM, MAC address is stored in SPI
flash which is accessed using MTD interface.

This patch delays the initialization of DaVinci EMAC driver
by changing module_init to late_initcall. This helps SPI and
MTD drivers to get initialized before EMAC thereby enabling
EMAC driver to read the MAC address while booting and use it.

ipv6: Update Neighbor Cache when IPv6 RA is received on a router

When processing a received IPv6 Router Advertisement, the kernel
creates or updates an IPv6 Neighbor Cache entry for the sender --
but presently this does not occur if IPv6 forwarding is enabled
(net.ipv6.conf.*.forwarding = 1), or if IPv6 Router Advertisements
are not accepted (net.ipv6.conf.*.accept_ra = 0), because in these
cases processing of the Router Advertisement has already halted.

This patch allows the Neighbor Cache to be updated in these cases,
while still avoiding any modification to routes or link parameters.

This continues to satisfy RFC 4861, since any entry created in the
Neighbor Cache as the result of a received Router Advertisement is
still placed in the STALE state.

There is a race condition in the time-wait sockets code that can lead

generation when the FIN,ACK from the peer finally arrives:

Say twdr->slot = 1 and we are running inet_twdr_hangman and in this
instance inet_twdr_do_twkill_work returns 1. At that point we will
mark slot 1 and schedule inet_twdr_twkill_work. We will also make
twdr->slot = 2.

Next, a connection is closed and tcp_time_wait(TCP_FIN_WAIT2, timeo)
is called which will create a new FIN_WAIT2 time-wait socket and will
place it in the last to be reached slot, i.e. twdr->slot = 1.

At this point say inet_twdr_twkill_work will run which will start
destroying the time-wait sockets in slot 1, including the just added
TCP_FIN_WAIT2 one.

To avoid this issue we increment the slot only if all entries in the
slot have been purged.

This change may delay the slots cleanup by a time-wait death row
period but only if the worker thread didn't had the time to run/purge
the current slot in the next period (6 seconds with default sysctl
settings). However, on such a busy system even without this change we
would probably see delays...

fib_trie: resize rework

Here is rework and cleanup of the resize function.

Some bugs we had. We were using ->parent when we should use
node_parent(). Also we used ->parent which is not assigned by
inflate in inflate loop.

Also a fix to set thresholds to power 2 to fit halve
and double strategy.

max_resize is renamed to max_work which better indicates
it's function.

Reaching max_work is not an error, so warning is removed.
max_work only limits amount of work done per resize.
(limits CPU-usage, outstanding memory etc).

The clean-up makes it relatively easy to add fixed sized
root-nodes if we would like to decrease the memory pressure
on routers with large routing tables and dynamic routing.
If we'll need that...

Its been tested with 280k routes.

sit: allow ip fragmentation when using nopmtudisc to fix package loss

if tunnel parameters have frag_off set to IP_DF, pmtudisc on the ipv4 link
will be performed by deriving the mtu from the ipv4 link and setting the
DF-Flag of the encapsulating IPv4 Header. If fragmentation is needed on the
way, the IPv4 pmtu gets adjusted, the ipv6 package will be resent eventually,
using the new and lower mtu and everyone is happy.

If the frag_off parameter is unset, the mtu for the tunnel will be derived
from the tunnel device or the ipv6 pmtu, which might be higher than the ipv4
pmtu. In that case we must allow the fragmentation of the IPv4 packet because
the IPv6 mtu wouldn't 'learn' from the adjusted IPv4 pmtu, resulting in
frequent icmp_frag_needed and package loss on the IPv6 layer.

This patch allows fragmentation when tunnel was created with parameter
nopmtudisc, like in ipip/gre tunnels.

qlge: Get rid of 'default' rx_ring type.

Currently we have three types of RX rings.

1) Default ring - services rx_ring for broadcast/multicast, handles
firmware events, and errors.

2) TX completion ring - handles only outbound completions.

3) RSS ring - handles only inbound completions.

This patch gets rid of the default ring type and moves it's functionality
into the first RSS ring.  This makes better use of MSIX vectors since
they are a limited resource on some platforms.

The `val' variable in ath5k_eeprom_read_turbo_modes() is used
uninitialized.  gcc 4.4.1 with -fno-inline-functions-called-once reports
it:

eeprom.c: In function 'ath5k_eeprom_read_turbo_modes':
eeprom.c:441: warning: 'val' may be used uninitialized in this function

Comparing the code to the Atheros HAL, it's clear that the split between
ath5k_eeprom_read_modes() and ath5k_eeprom_read_turbo_modes() was
incorrect.

The Atheros HAL reads both turbo and non-turbo data from EEPROM in one
function.  Some turbo mode parameters are derived from the same EEPROM
values as non-turbo parameters, just from different bits.
