r8169: fix auto speed down issue

2013-04-25T19:25:48+00:00

commit e2409d83434d77874b461b78af6a19cd6e6a1280 upstream.

It would cause no link after suspending or shutdowning when the
nic changes the speed to 10M and connects to a link partner which
forces the speed to 100M.

Check the link partner ability to determine which speed to set.

pch_gbe: fix ip_summed checksum reporting on rx

2013-04-10T02:20:15+00:00

[ Upstream commit 76a0e68129d7d24eb995a6871ab47081bbfa0acc ]

skb->ip_summed should be CHECKSUM_UNNECESSARY when the driver reports that
checksums were correct and CHECKSUM_NONE in any other case. They're
currently placed vice versa, which breaks the forwarding scenario. Fix it
by placing them as described above.

ks8851: Fix interpretation of rxlen field.

2013-04-10T02:20:15+00:00

[ Upstream commit 14bc435ea54cb888409efb54fc6b76c13ef530e9 ]

According to the Datasheet (page 52):
15-12 Reserved
11-0 RXBC Receive Byte Count
This field indicates the present received frame byte size.

The code has a bug:
                 rxh = ks8851_rdreg32(ks, KS_RXFHSR);
                 rxstat = rxh & 0xffff;
                 rxlen = rxh >> 16; // BUG!!! 0xFFF mask should be applied

DM9000B: driver initialization upgrade

2013-04-10T02:20:14+00:00

[ Upstream commit 6741f40d198c6a5feb23653a1efd4ca47f93d83d ]

Fix bug for DM9000 revision B which contain a DSP PHY

DM9000B use DSP PHY instead previouse DM9000 revisions' analog PHY,
So need extra change in initialization, For
explicity PHY Reset and PHY init parameter, and
first DM9000_NCR reset need NCR_MAC_LBK bit by dm9000_probe().

Following DM9000_NCR reset cause by dm9000_open() clear the
NCR_MAC_LBK bit.

Without this fix, Power-up FIFO pointers error happen around 2%
rate among Davicom's customers' boards. With this fix, All above
cases can be solved.

To restart tx queue use netif_wake_queue() intead of netif_start_queue()
so that net schedule will restart transmission immediately which will
increase network performance while doing huge data transfers.

sky2: Threshold for Pause Packet is set wrong

[ Upstream commit 74f9f42c1c1650e74fb464f76644c9041f996851 ]

The sky2 driver sets the Rx Upper Threshold for Pause Packet generation to a
wrong value which leads to only 2kB of RAM remaining space. This can lead to
Rx overflow errors even with activated flow-control.

Fix: We should increase the value to 8192/8

sky2: Receive Overflows not counted

2013-04-10T02:20:10+00:00

[ Upstream commit 9cfe8b156c21cf340b3a10ecb3022fbbc1c39185 ]

The sky2 driver doesn't count the Receive Overflows because the MAC
interrupt for this event is not set in the MAC's interrupt mask.
The MAC's interrupt mask is set only for Transmit FIFO Underruns.

Fix: The correct setting should be (GM_IS_TX_FF_UR | GM_IS_RX_FF_OR)
Otherwise the Receive Overflow event will not generate any interrupt.
The  Receive Overflow interrupt is handled correctly

ixgbe: fix registration order of driver and DCA nofitication

commit f01fc1a82c2ee68726b400fadb156bd623b5f2f1 upstream.

ixgbe_notify_dca cannot be called before driver registration
because it expects driver's klist_devices to be allocated and

tg3: fix length overflow in VPD firmware parsing

2013-04-10T02:20:04+00:00

commit 715230a44310a8cf66fbfb5a46f9a62a9b2de424 upstream.

Commit 184b89044fb6e2a74611dafa69b1dce0d98612c6 ("tg3: Use VPD fw version
when present") introduced VPD parsing that contained a potential length
overflow.

Limit the hardware's reported firmware string length (max 255 bytes) to
stay inside the driver's firmware string length (32 bytes). On overflow,
truncate the formatted firmware string instead of potentially overwriting
portions of the tg3 struct.
