This never, ever, happens.

Neighbour entries are always tied to one address family, and therefore
one set of dst_ops, and therefore one dst_ops->protocol "hh_type"
value.

This capability was blindly imported by Alexey Kuznetsov when he wrote
the neighbour layer.

Get rid of all of the useless and costly indirection
by doing the neigh hash table lookup directly inside
of the neighbour binding.

Rename from arp_bind_neighbour to rt_bind_neighbour.

Use new helpers {__,}ipv4_neigh_lookup()

In rt_bind_neighbour() get rid of useless tests which
are never true in the context this function is called,
namely dev is never NULL and the dst->neighbour is
always NULL.

And mask the hash function result by simply shifting
down the "->hash_shift" most significant bits.

Currently which bits we use is arbitrary since jhash
produces entropy evenly across the whole hash function
result.

But soon we'll be using universal hashing functions,
and in those cases more entropy exists in the higher
bits than the lower bits, because they use multiplies.

Signed-off-by: David S. Miller <davem@davemloft.net>

This is a backport from the vendor driver of support for the newer Optima
(Prime and 2) chipsets. It also includes some setup changes for the
current Optima chip as well. The code and comments intentionally
mirror the vendor sk98lin driver to allow for easier maintenance.

Although this adds support for new chip id's, these chip id's are not
used by any of the current PCI device id's listed in the driver.
The patch is just to get initial infrastructure in place to handle them
when they come.

I don't have access to any of this hardware to actually test it yet.

Implementing this callback function will cause mac80211 refrain from
going to powersave state when there are still untransmitted TX frames
in the queues.
This would exactly mimic the behaviour of the legacy vendor driver which
also doesn't go in powersave mode if there are still TX frames that are not
transmitted.
This should make powersaving and rt2x00 a better couple.
