ll_temac: Reset dma descriptors indexes on ndo_open

2013-10-01T16:31:35+00:00

The dma descriptors indexes are only initialized on the probe function.

If a packet is on the buffer when temac_stop is called, the dma
descriptors indexes can be left on a incorrect state where no other
package can be sent.

So an interface could be left in an usable state after ifdow/ifup.

This patch makes sure that the descriptors indexes are in a proper
status when the device is open.

ethernet: moxa: fix incorrect placement of __initdata tag

2013-10-01T05:16:43+00:00

__initdata tag should be placed between the variable name and equal
sign for the variable to be placed in the intended .init.data section.

In this particular case __initdata is incorrect as moxart_mac_driver
can be used after the driver gets initialized.

Also while at it static-ize moxart_mac_driver.

powerpc/83xx: gianfar_ptp: select 1588 clock source through dts file

2013-10-01T04:17:16+00:00

Currently IEEE 1588 timer reference clock source is determined through
hard-coded value in gianfar_ptp driver. This patch allows to select ptp
clock source by means of device tree file node.

For instance:

	fsl,cksel = <0>;

for using external (TSEC_TMR_CLK input) high precision timer
reference clock.

Other acceptable values:

	<1> : eTSEC system clock
	<2> : eTSEC1 transmit clock
	<3> : RTC clock input

When this attribute isn't used, eTSEC system clock will serve as
IEEE 1588 timer reference clock.

bonding: Fix broken promiscuity reference counting issue

2013-10-01T04:10:55+00:00

Recently grabbed this report:
https://bugzilla.redhat.com/show_bug.cgi?id=1005567

Of an issue in which the bonding driver, with an attached vlan encountered the
following errors when bond0 was taken down and back up:

dummy1: promiscuity touches roof, set promiscuity failed. promiscuity feature of
device might be broken.

The error occurs because, during __bond_release_one, if we release our last
slave, we take on a random mac address and issue a NETDEV_CHANGEADDR
notification.  With an attached vlan, the vlan may see that the vlan and bond
mac address were in sync, but no longer are.  This triggers a call to dev_uc_add
and dev_set_rx_mode, which enables IFF_PROMISC on the bond device.  Then, when
we complete __bond_release_one, we use the current state of the bond flags to
determine if we should decrement the promiscuity of the releasing slave.  But
since the bond changed promiscuity state during the release operation, we
incorrectly decrement the slave promisc count when it wasn't in promiscuous mode
to begin with, causing the above error

Fix is pretty simple, just cache the bonding flags at the start of the function
and use those when determining the need to set promiscuity.

This is also needed for the ALLMULTI flag

xen-netback: Handle backend state transitions in a more robust way

2013-09-30T19:13:28+00:00

When the frontend state changes netback now specifies its desired state to
a new function, set_backend_state(), which transitions through any
necessary intermediate states.
This fixes an issue observed with some old Windows frontend drivers where
they failed to transition through the Closing state and netback would not
behave correctly.

net: qmi_wwan: fix Cinterion PLXX product ID

2013-09-30T19:04:07+00:00

Cinterion PLXX LTE devices have a 0x0060 product ID, not 0x12d1.

The blacklisting in the serial/option driver does actually use the correct PID,
as per commit 8ff10bdb14a52e3f25d4ce09e0582a8684c1a6db ('USB: Blacklisted
Cinterion's PLxx WWAN Interface').
