gianfar: ethernet vanishes after restoring from hibernation
If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.
For example:
~# ifconfig eth0 down
~# echo disk > /sys/power/state
<trigger a restore from hibernation>
~# ifconfig eth0 up
SIOCSIFFLAGS: No such device
This happens because the restore function bails out early upon
finding devices that were not up at hibernation. In doing so,
it never gets to the netif_device_attach call at the end of
the restore function. Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.

pkt_sched: enable QFQ to support TSO/GSO
If the max packet size for some class (configured through tc) is
violated by the actual size of the packets of that class, then QFQ
would not schedule classes correctly, and the data structures
implementing the bucket lists may get corrupted. This problem occurs
with TSO/GSO even if the max packet size is set to the MTU, and is,
e.g., the cause of the failure reported in [1]. Two patches have been
proposed to solve this problem in [2], one of them is a preliminary
version of this patch.
This patch addresses the above issues by: 1) setting QFQ parameters to
proper values for supporting TSO/GSO (in particular, setting the
maximum possible packet size to 64KB), 2) automatically increasing the
max packet size for a class, lmax, when a packet with a larger size
than the current value of lmax arrives.
The drawback of the first point is that the maximum weight for a class
is now limited to 4096, which is equal to 1/16 of the maximum weight
sum.
Finally, this patch also forcibly caps the timestamps of a class if
they are too high to be stored in the bucket list. This capping, taken
from QFQ+ [3], handles the unfrequent case described in the comment to
the function slot_insert.

GCC is correct. In promiscuous mode 'mc_filter' will be used
uninitialized in set_rx_mode_8012(), which is apparently inlined into
set_rx_mode().
But it turns out set_rx_mode_8012() will never be called, since
net_local.chip_type will always be RTL8002. So we can just remove
set_rx_mode_8012() and do some related cleanups.

cpsw: fix leaking IO mappings
The CPSW driver remaps two different IO regions, but fails to unmap them
both. This patch fixes the issue by calling iounmap in the appropriate
places.

cpsw: rename register banks to match the reference manual, part 2
The code mixes up the CPSW_SS and the CPSW_WR register naming. This patch
changes the names to conform to the published Technical Reference Manual
from TI, in order to make working on the code less confusing.

net: fix bridge notify hook to manage flags correctly
The bridge notify hook rtnl_bridge_notify() was not handling the
case where the master flags was set or with both flags set. First
flags are not being passed correctly and second the logic to parse
them is broken.
This patch passes the original flags value and fixes the
logic.

macb: Keep driver's speed/duplex in sync with actual NCFGR
When underlying phy driver restores its state very fast after being brought
down and up so that macb driver function macb_handle_link_change() was never
called with link state "down", driver's internal representation of phy speed
and duplex (bp->speed and bp->duplex) didn't change. So, macb driver sees no
reason to perform actual write to the NCFGR register, although the speed and
duplex settings in that register were reset when interface was brought down
and up. In that case actual phy speed and duplex differ from NCFGR settings.
The patch fixes that by keeping internal driver representation of speed and
duplex in sync with actual content of NCFGR.
