Revert "xen/blkback: Don't trust the handle from the frontend."

2013-04-05T17:04:52+00:00

This reverts commit c93c85196e2c7001daa8a04b83a9d6dd4febfb59 which is
commit 01c681d4c70d64cb72142a2823f27c4146a02e63 upstream.

It shouldn't have been applied to the 3.4-stable tree, sorry about that.

bonding: get netdev_rx_handler_unregister out of locks

2013-04-05T17:04:52+00:00

[ Upstream commit fcd99434fb5c137274d2e15dd2a6a7455f0f29ff ]

Now that netdev_rx_handler_unregister contains synchronize_net(), we need
to call it outside of bond->lock, cause it might sleep. Also, remove the
already unneded synchronize_net().

smsc75xx: fix jumbo frame support

2013-04-05T17:04:51+00:00

[ Upstream commit 4c51e53689569398d656e631c17308d9b8e84650 ]

This patch enables RX of jumbo frames for LAN7500.

Previously the driver would transmit jumbo frames succesfully but
would drop received jumbo frames (incrementing the interface errors
count).

With this patch applied the device can succesfully receive jumbo
frames up to MTU 9000 (9014 bytes on the wire including ethernet
header).

pch_gbe: fix ip_summed checksum reporting on rx

2013-04-05T17:04:51+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.

2013-04-05T17:04:41+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

2013-04-05T17:04:40+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.

aoe: reserve enough headroom on skbs

2013-04-05T17:04:40+00:00

[ Upstream commit 91c5746425aed8f7188a351f1224a26aa232e4b3 ]

Some network drivers use a non default hard_header_len

Transmitted skb should take into account dev->hard_header_len, or risk
crashes or expensive reallocations.

In the case of aoe, lets reserve MAX_HEADER bytes.

David reported a crash in defxx driver, solved by this patch.

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.
