The commits f3db4851 ([NETNS][IPV6] ip6_fib - fib6_clean_all handle several 
network namespaces) and 69ddb805 ([NETNS][IPV6] route6 - Make proc entry 
/proc/net/rt6_stats per namespace) made some proc files per net.

Both of them introduced potential OOPS - get_proc_net can return NULL, but
this check is lost - and a struct net leak - in case single_open() fails the
previously got net is not put.

Kill all these bugs with one patch.

Currently each vlan_groupd contains 8 pointers on arrays with 512
pointers on struct net_device each  :)  Such a construction "in many
cases ... wastes memory".

My proposal is to allow for some of these arrays pointers be NULL,
meaning that there are no devices in it. When a new device is added
to the vlan_group, the appropriate array is allocated.

The check in vlan_group_get_device's is safe, since the pointer
vg->vlan_devices_arrays[x] can only switch from NULL to not-NULL.
The vlan_group_prealloc_vid() is guarded with rtnl lock and is
also safe.

I've checked (I hope that) all the places, that use these arrays
and found, that the register_vlan_dev is the only place, that can
put a vlan device on an empty vlan_group.

Rough calculations shows, that after the patch a setup with a
single vlan dev (or up to 512 vlans with sequential vids) will
occupy approximately 8 times less memory.

The question I have is - does this patch makes sense, or a totally
new structures are required to store the vlan_devs?

This patch adds support for BCM5481 PHY. Unfortunately it's hard to
get specifications for this PHY, so its special register 0x18 isn't
annotated properly (but we know it's used to set up the delays).

I've kept the magic numbers, so we'll not forget to fix it at the
first opportunity, and will name that register and its bits correctly.

p.s. also fixed the line with broken indention, introduced by
