This patch modifies the pcs mode support for SGMII. Even though

On the MRF24J40, link-layer acknowledgment request and retry must be
turned on explicitly for each packet. Turn this on in the hardware based
on the FC_ACK_REQ bit being set in the packet.
Also, now that failure to receive an ACK will cause the hardware to report
failure of transmission, change the log level for this failure to debug
level.

It served no purpose: we never call it from anywhere in the stack
and the only driver that did implement it (fakehard) merely provided
a dummy value.
There is also considerable doubt whether it would make sense to

We have a race condition if we try to rmmod bonding and simultaneously add
a bond master through sysfs. In bonding_exit() we first remove the devices
(through rtnl_link_unregister() ) and only after that we remove the sysfs.
If we manage to add a device through sysfs after that the devices were
removed - we'll end up with that device/sysfs structure and with the module
unloaded.
Fix this by first removing the sysfs and only after that calling
rtnl_link_unregister().

John W. Linville says:
====================
Here are some more fixes intended for the 3.9 stream...
Regarding the mac80211 bits, Johannes says:
"I had changed the idle handling to simplify it, but broken the
sequencing of commands, at least for ath9k-htc, one patch restores the
sequence. The other patch fixes a crash Jouni found while stress-testing
the remain-on-channel code, when an item is deleted the work struct can
run twice and crash the second time."
As for the iwlwifi bits, Johannes says:
"The only fix here is to the passive-no-RX firmware regulatory
enforcement driver support code to not drop auth frames in quick
succession, leading to not being able to connect to APs on passive
channels in certain circumstances."
Don't forget the NFC bits, about which Samuel says:
"This time we have:
- A crash fix for when a DGRAM LLCP socket is listening while the NFC adapter
is physically removed.
- A potential double skb free when the LLCP socket receive queue is full.
- A fix for properly handling multiple and consecutive LLCP connections, and
not trash the socket ack log.
- A build failure for the MEI microread physical layer, now that the MEI bus
APIs have been merged into char-misc-next."
On top of that, Stone Piao provides an mwifiex fix to avoid accessing
beyond the end of a buffer.

Since of_get_mac_address() is now defined even if CONFIG_OF_NET
is not configured, the ifdef around the code calling it is no longer
necessary and can be removed.
Similar, since of_get_phy_mode() is now defined as dummy function
if OF_NET is not configured, it is no longer necessary to provide
an OF dependent function as front-end. Also, the function depends
on OF_NET, not on OF, so the conditional code was not correct anyway.
Drop the front-end function and call of_get_phy_mode() directly.
