Based on investigation of the legacy drivers, I have made the
following assumptions of the antenna setup:
- R77 is the TX antenna configuration
- RF2529 fetches default antenna selection from NIC eeprom word
With these assumptions we can change the antenna configuration
to correctly read both antenna setup values and correctly
configure the antenna. And we can now also configure the antenna
for RF2529 without a double antenna.

When mac80211 indicates that the default antenna setup
should be used _and_ that this default setup is SW_DIVERSITY.
This requires sampling and storing the RSSI per antenna
and check once every 2 seconds to determine if the RSSI
has changed significantly. Once this is the case we should sample
the other antenna for a short period and evaluate if
we need to swap antenna or not.

mac80211 has 3 values for the antenna setup:
0 - default
1 - use antenna 1
2 - use antenna 2
This means that rt2x00 should store the default value
from the EEPROM somwhere and use that when mac80211 indicates
that the antenna setup is 0.
This also implies that rt2x00 should no longer write the
hw->config.antenna_sel_* values based on the EEPROM input.
This also adds the basis in rt2x00lib for correct software
diversity handling. By default rt2x00lib will now configure
antenna B instead of hardware diversity.

The network namespace pointer can be stored into the dst_ops structure.

The garbage collection function receive the dst_ops structure as
parameter. This is useful for the next incoming patchset because it
will need the dst_ops (there will be several instances) and the
network namespace pointer (contained in the dst_ops).
The protocols which do not take care of the namespaces will not be
impacted by this change (expect for the function signature), they do
just ignore the parameter.

Currently, sizeof(struct fib_alias) is 24 or 48 bytes on 32/64 bits
arches.
Because of SLAB_HWCACHE_ALIGN requirement, these are rounded to 32 and
64 bytes respectively.
This patch moves rcu to the end of fib_alias, and conditionally
defines it only for CONFIG_IP_FIB_TRIE.
We also remove SLAB_HWCACHE_ALIGN requirement for fib_alias and
fib_node objects because it is not necessary.
(BTW SLUB currently denies it for objects smaller than
cache_line_size() / 2, but not SLAB)
Finally, sizeof(fib_alias) go back to 16 and 32 bytes.
Then, we can embed one fib_alias on each fib_node, to favor locality.
Most of the time access to the fib_alias will be free because one
cache line contains both the list head (fn_alias) and (one of) the
list element.

node_parent() and tnode_get_child() currently use rcu_dereference().
These functions are called from both
- readers only paths (where rcu_dereference() is needed), and
- writer path (where rcu_dereference() is not needed)
To make explicit where rcu_dereference() is really needed, I
introduced new node_parent_rcu() and tnode_get_child_rcu() functions
which use rcu_dereference(), while node_parent() and tnode_get_child()
dont use it.
Then I changed calling sites where rcu_dereference() was really needed
to call the _rcu() variants.
This should have no impact but for alpha architecture, and may help
future sparse checks.
