The freescale arm i.MX series platform can support this driver, and
usually the arm cpu works in the little endian mode by default, while
device tree entry value is stored in big endian format, we should use
be32_to_cpup() to handle them, after modification, it can work well
both on the le cpu and be cpu.

FCoE target mode was experiencing issues due to the fact that we were
sending up data frames that were padded to 60 bytes after the DDP logic had
already stripped the frame down to 52 or 56 depending on the use of VLANs.
This was resulting in the FCoE DDP logic having issues since it thought the
frame still had data in it due to the padding.
To resolve this, adding code so that we do not pad FCoE frames prior to
handling them to the stack.

The following commit couldn't work if the RMCR is not set to 1.
"net: sh_eth: fix the rxdesc pointer when rx descriptor empty happens"
commit id 79fba9f517
If RMCR is not set, the controller will clear the EDRRR after it received
a frame. In this case, the driver doesn't need to fix the value of
cur_rx/dirty_rx. The driver only needs it when the controll detects
receive descriptors are empty.

The 8168evl (RTL_GIGA_MAC_VER_34) based Gigabyte GA-990FXA motherboards
are very prone to NETDEV watchdog problems without this change. See
https://bugzilla.kernel.org/show_bug.cgi?id=42899 for instance.
I don't know why it *works*. It's depressingly effective though.
For the record:
- the problem may go along IOMMU (AMD-Vi) errors but it really looks
like a red herring.
- the patch sets the RX_MULTI_EN bit. If the 8168c doc is any guide,
the chipset now fetches several Rx descriptors at a time.
- long ago the driver ignored the RX_MULTI_EN bit.
e542a2269f changed the RxConfig
settings. Whatever the problem it's now labeled a regression.
- Realtek's own driver can identify two different 8168evl devices
(CFG_METHOD_16 and CFG_METHOD_17) where the r8169 driver only
sees one. It sucks.

If usbnet is resumed by remote wakeup, generally there are
some packets comming to be handled, so allocate and submit
rx URBs in usbnet_resume to avoid delays introduced by tasklet.
Otherwise, usbnet may have been runtime suspended before the
usbnet_bh is executed to schedule Rx URBs.
Without the patch, usbnet can't recieve any packets from peer
in runtime suspend state if runtime PM is enabled and
autosuspend_delay is set as zero.

Ignoring interfaces with additional descriptors is not a reliable
method for locating the correct interface on Gobi devices. There
is at least one device where this method fails:
https://bbs.archlinux.org/viewtopic.php?id=143506
The result is that the AT command port (interface #2) is hidden
from qcserial, preventing traditional serial modem usage:
[ 15.562552] qmi_wwan 4-1.6:1.0: cdc-wdm0: USB WDM device

[ 15.564328] qmi_wwan: probe of 4-1.6:1.3 failed with error -22

[ 15.569440] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB0
[ 15.570372] qcserial 4-1.6:1.3: Qualcomm USB modem converter detected
[ 15.570430] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB1
Use static interface numbers taken from the interface map in
qcserial for all Gobi devices instead:
Gobi 1K USB layout:
0: serial port (doesn't respond)
1: serial port (doesn't respond)
2: AT-capable modem port
3: QMI/net
Gobi 2K+ USB layout:
0: QMI/net
1: DM/DIAG (use libqcdm from ModemManager for communication)
2: AT-capable modem port
3: NMEA
This should be more reliable over all, and will also prevent the
noisy "probe failed" messages. The whitelisting logic is expected
to be replaced by direct interface number matching in 3.6.

This patch fixes a memory leak that was introduced in the 3.4 kernel. The
leak occurred when FCoE was enabled and traffic was passed over the FCoE
rings reserved for FCoE. The memory leak was due to us not populating the
