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

[   15.570430] 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.

On a freescale imx6q platform, a hardware phy chip KSZ9021 is
recognized as a KS8001 chip by the current driver like this:
eth0: Freescale FEC PHY driver [Micrel KS8001 or KS8721]

KSZ9021 has phy_id 0x00221610, while KSZ8001 has phy_id
0x0022161a, the current phy_id_mask (0x00fffff0/0x00ffff10) can't
distinguish them. So change phy_id_mask to resolve this problem.

Although the micrel datasheet says that the 4 LSB of phyid2 register
contains the chip revision number and the current driver is designed
to follow this rule, in reality the chip implementation doesn't follow
it.

This patch fixes a potential hole when configuring the cycle counter used to
generate the nanosecond time clock. This clock is based off of the SYSTIME
registers along with the TIMINCA registers. The TIMINCA register determines
the increment to be added to the SYSTIME registers every DMA clock tick. This
register needs to be reconfigured whenever the link-speed changes. However,
the value calculated stays the same when link is down and when link is up.
Misconfiguration can occur if the link status changes due to a reset, which
causes the TIMINCA register to be reset. This reset puts the device in an
unstable state where the SYSTIME registers stop incrementing and the PTP
protocol does not function.

The solution is to double check the TIMINCA value and always reset the value
if the register is zero. This prevents a misconfiguration bug that halts the
PHC.

bnx2x driver incorrectly sets ip_summed to CHECKSUM_UNNECESSARY on
encapsulated segments. TCP stack happily accepts frames with bad
checksums, if they are inside a GRE or IPIP encapsulation.

Our understanding is that if no IP or L4 csum validation was done by the
hardware, we should leave ip_summed as is (CHECKSUM_NONE), since
hardware doesn't provide CHECKSUM_COMPLETE support in its cqe.

Then, if IP/L4 checksumming was done by the hardware, set
CHECKSUM_UNNECESSARY if no error was flagged.

In the transmit path of the bonding driver, skb->cb is used to
stash the skb->queue_mapping so that the bonding device can set its
own queue mapping.  This value becomes corrupted since the skb->cb is
also used in __dev_xmit_skb.

When transmitting through bonding driver, bond_select_queue is
called from dev_queue_xmit.  In bond_select_queue the original
skb->queue_mapping is copied into skb->cb (via bond_queue_mapping)
and skb->queue_mapping is overwritten with the bond driver queue.

Subsequently in dev_queue_xmit, __dev_xmit_skb is called which writes
the packet length into skb->cb, thereby overwriting the stashed
queue mappping.  In bond_dev_queue_xmit (called from hard_start_xmit),
the queue mapping for the skb is set to the stashed value which is now
the skb length and hence is an invalid queue for the slave device.

If we want to save skb->queue_mapping into skb->cb[], best place is to
add a field in struct qdisc_skb_cb, to make sure it wont conflict with
other layers (eg : Qdiscc, Infiniband...)

This patchs also makes sure (struct qdisc_skb_cb)->data is aligned on 8
bytes :

netem qdisc for example assumes it can store an u64 in it, without
misalignment penalty.

Note : we only have 20 bytes left in (struct qdisc_skb_cb)->data[].
The largest user is CHOKe and it fills it.
