Fix an overflow bug in vmxnet3 Tx descriptor

This patch fixes a bug where a 16K buffer on a Tx descriptor was overflowing
into the 'gen' bit in the descriptor thereby corrupting the descriptor and
stalling the transmit ring.

Respect the interrupt type set in VM configuration.

When interrupt type is not auto, do not ignore the interrupt type set from
VM configuration.

net-next: vmxnet3 fixes [4/5] Do not reset when the device is not opened

2010-07-19T20:15:50+00:00

Hold rtnl_lock to get the right link state.

While asynchronously resetting the device, hold rtnl_lock to get the
right value from netif_running. If a reset is scheduled, and the device
goes thru close and open, it may happen that reset and open may run in
parallel. Holding rtnl_lock will avoid this.

net-next: vmxnet3 fixes [3/5] Initialize link state at probe time

2010-07-18T21:48:17+00:00

This change initializes the state of link at the time when driver is
loaded. The ethtool output for 'link detected' and 'link speed'
is thus valid even before the interface is brought up.

net-next: vmxnet3 fixes [2/5] Interrupt control bitmap

2010-07-16T05:18:47+00:00

A new bit map 'intrCtrl' is introduced in the DriverShared area. The 
driver should update VMXNET3_IC_DISABLE_ALL bit before writing IMR.

vmxnet3: Remove incorrect implementation of ethtool_ops::get_flags()

2010-06-30T21:09:36+00:00

Only some netdev feature flags correspond directly to ethtool feature
flags.  ethtool_op_get_flags() does the right thing.

drivers/net/vmxnet3: Use kzalloc

2010-05-18T05:55:10+00:00

Use kzalloc rather than the combination of kmalloc and memset.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// 
@@
expression x,size,flags;
statement S;
@@

-x = kmalloc(size,flags);
+x = kzalloc(size,flags);
 if (x == NULL) S
-memset(x, 0, size);

net: trans_start cleanups

2010-05-10T12:01:31+00:00

Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Drivers can avoid one cache miss
(on dev->trans_start) in their start_xmit() handler.

Exceptions are NETIF_F_LLTX drivers
