Neither CMD_802_11_PAIRWISE_TSC nor CMD_802_11_GROUP_TSC is used or
documented. It might have something to do with TKIP sequence counters,
but that's just an educated guess. Remove all occurences of them.
CMD_CODE_DNLD is also neither used nor documented.

The CMD_MAC_CONTROL can be used for other things than just filtering

Introduce an inline net_eq() to compare two namespaces.
Without CONFIG_NET_NS, since no namespace other than &init_net
exists, it is always 1.
We do not need to convert 1) inline vs inline and
2) inline vs &init_net comparisons.

Each MIPv6 XFRM state (DSTOPT/RH2) holds either destination or source
address to be mangled in the IPv6 header (that is "CoA").
On Inter-MN communication after both nodes binds each other,
they use route optimized traffic two MIPv6 states applied, and
both source and destination address in the IPv6 header
are replaced by the states respectively.
The packet format is correct, however, next-hop routing search
are not.
This patch fixes it by remembering address pairs for later states.

The iwlxxxx_pci_remove functions are not needed when drivers are not
compiled as modules - they can thus be discarded at kernel link time.
This is already captured by having them as __devexit_p in the pci_driver
struct - these are supposed to be pointers to __devexit functions, but was not.
This is now fixed.
This problem was reported by Toralf Forster when testing the compilation of
2.6.25-rc6.

This patch fixes a synchronization problem on the 4965 and 3945 with the
mac start callback routine. The problem is that this function exits BEFORE the
'xxx_alive_start' has completed. This can lead to a problem if a
subsequent MAC callback attempts to issue a firmware command.

Proxy neighbors do not have any reference counting, so any caller
of pneigh_lookup (unless it's a netlink triggered add/del routine)
should _not_ perform any actions on the found proxy entry.
There's one exception from this rule - the ipv6's ndisc_recv_ns()
uses found entry to check the flags for NTF_ROUTER.
This creates a race between the ndisc and pneigh_delete - after
the pneigh is returned to the caller, the nd_tbl.lock is dropped
and the deleting procedure may proceed.
One of the fixes would be to add a reference counting, but this
problem exists for ndisc only. Besides such a patch would be too
big for -rc4.
So I propose to introduce a __pneigh_lookup() which is supposed
to be called with the lock held and use it in ndisc code to check
the flags on alive pneigh entry.
Changes from v2:
As David noticed, Exported the __pneigh_lookup() to ipv6 module.
The checkpatch generates a warning on it, since the EXPORT_SYMBOL
does not follow the symbol itself, but in this file all the
exports come at the end, so I decided no to break this harmony.
Changes from v1:
Fixed comments from YOSHIFUJI - indentation of prototype in header
and the pndisc_check_router() name - and a compilation fix, pointed
by Daniel - the is_routed was (falsely) considered as uninitialized
by gcc.
