This reverts commit 3d5fdff4.

Ben Hutchings pointed out that the commit isn't safe since it assumes
that the structure used by the driver is iw_point, when in fact there's
no way to know about that.

Fortunately, the only driver in the tree that ever runs this code path
is the wilc1000 staging driver, so it doesn't really matter.

Clearly I should have investigated this better before applying, sorry.

When there is no AC power, NIC may not work after changing mac address.
Please refer to following link.
http://www.spinics.net/lists/netdev/msg356572.html

This issue is caused by runtime power management. When there is no AC
power, if we put NIC down (ifconfig down), the driver will be in runtime
suspend state and hardware will be put into D3 state. During this time,
driver cannot access hardware regisers. So if you set new mac address
during this time, it will not be set to hardware. After resume, NIC will
keep using the old mac address and the network will not work normally.

In this patch I add detecting runtime pm status when setting mac address.
If driver is in runtime suspend state, it will skip setting mac address, keep
the new mac address, and set the new mac address during runtime resume.

If we set or get hardware wol setting in runtime suspend state, because

Prior to this patch, once sctp received SHUTDOWN or shutdown with RD,
sk->sk_shutdown would be set with RCV_SHUTDOWN, and all events would
be dropped in sctp_ulpq_tail_event(). It would cause:

1. some notifications couldn't be received by users. like
   SCTP_SHUTDOWN_COMP generated by sctp_sf_do_4_C().

2. sctp would also never trigger sk_data_ready when the association
   was closed, making it harder to identify the end of the association
   by calling recvmsg() and getting an EOF. It was not convenient for
   kernel users.

The check here should be stopping delivering DATA chunks after receiving
SHUTDOWN, and stopping delivering ANY chunks after sctp_close().

So this patch is to allow notifications to enqueue into receive queue
even if sk->sk_shutdown is set to RCV_SHUTDOWN in sctp_ulpq_tail_event,
but if sk->sk_shutdown == RCV_SHUTDOWN | SEND_SHUTDOWN, it drops all
events.

tcp_select_initial_window() intends to advertise a window
scaling for the maximum possible window size. To do so,
it considers the maximum of net.ipv4.tcp_rmem[2] and
net.core.rmem_max as the only possible upper-bounds.
However, users with CAP_NET_ADMIN can use SO_RCVBUFFORCE
to set the socket's receive buffer size to values
larger than net.ipv4.tcp_rmem[2] and net.core.rmem_max.
Thus, SO_RCVBUFFORCE is effectively ignored by
tcp_select_initial_window().

To fix this, consider the maximum of net.ipv4.tcp_rmem[2],

Following the previous patch, RXSCs are held and properly refcounted in
the RX path (instead of being implicitly held by their SA), so the SA
doesn't need to hold a reference on its parent RXSC.

This also avoids panics on module unload caused by the double layer of
RCU callbacks (call_rcu frees the RXSA, which puts the final reference
on the RXSC and allows to free it in its own call_rcu) that commit
b196c22a ("macsec: add rcu_barrier() on module exit") didn't
protect against.
There were also some refcounting bugs in macsec_add_rxsa where I didn't

Problem is the credit pool is shared by both PFs and VFs,
