Use RTM_NEWNEIGH and RTM_DELNEIGH to allow updating of entries
in bridge forwarding table. This allows manipulating static entries
which is not possible with existing tools.
Example (using bridge extensions to iproute2)
# br fdb add 00:02:03:04:05:06 dev eth0

This allows applications to query and monitor bridge forwarding
table in the same method used for neighbor table. The forward table
entries are returned in same structure format as used by the ioctl.
If more information is desired in future, the netlink method is
extensible.
Example (using bridge extensions to iproute2)
# br monitor

In some cases, look up of forward database entry is done with RCU;
and for others no RCU is needed because of locking. Split the two
cases into two differnt loops (and take off inline).

We currently run this timer exactly once when

also simplify some code using the timer.

The only thing that using crypto_blkcipher with ecb does over just using
arc4 directly is wrapping the encrypt/decrypt function into a for loop,
looping over each individual character.
To be able to do this, it pulls in around 40 kb worth of unnecessary
kernel modules (at least on a MIPS embedded device).
Using arc4 directly not only eliminates those dependencies, it also makes
the code smaller.

The commit "mac80211: reply to directed probes in IBSS" changed ad-hoc
specific code to respond to unicast probe requests, even if
drv_tx_last_beacon returns false, however due to confusion over the
meaning of the IEEE80211_RX_RA_MATCH flag, it also unconditionally
enabled responding to multicast probe requests.
Fix this by explicitly checking for a multicast destination address
instead.

--ctdir ORIGINAL matches REPLY packets, and vv:
userspace sets "invert_flags &= ~XT_CONNTRACK_DIRECTION" in ORIGINAL
case.
Thus: (CTINFO2DIR(ctinfo) == IP_CT_DIR_ORIGINAL) ^
!!(info->invert_flags & XT_CONNTRACK_DIRECTION))
yields "1 ^ 0", which is true -> returns false.
Reproducer:
iptables -I OUTPUT 1 -p tcp --syn -m conntrack --ctdir ORIGINAL

We currently use a percpu spinlock to 'protect' rule bytes/packets
counters, after various attempts to use RCU instead.
Lately we added a seqlock so that get_counters() can run without
blocking BH or 'writers'. But we really only need the seqcount in it.
Spinlock itself is only locked by the current/owner cpu, so we can
remove it completely.
This cleanups api, using correct 'writer' vs 'reader' semantic.
At replace time, the get_counters() call makes sure all cpus are done
using the old table.

ipv6 fib lookup can set RT6_LOOKUP_F_IFACE flag to restrict search
to an interface, but this flag cannot be set via struct flowi.
Also, it cannot be set via ip6_route_output: this function uses the
passed sock struct to determine if this flag is required
(by testing for nonzero sk_bound_dev_if).
Work around this by passing in an artificial struct sk in case
'strict' argument is true.
This is required to replace the rt6_lookup call in xt_addrtype.c with
nf_afinfo->route().

reading count of items in SEQOF field, only the lower byte of word is
stored. This may lead to corrupted read and communication shutdown.

Sometime the ASCONF_ACK parameters can equal to the fourfold of

ASCONF parameter is :
Unrecognized Parameter (4 bytes)
ASCONF_ACK parameter should be:
Error Cause Indication parameter (8 bytes header)
+ Error Cause (4 bytes header)
+ Unrecognized Parameter (4bytes)
Four 4bytes Unrecognized Parameters in ASCONF chunk will cause panic.
