vio: fix reuse of vio_dring slot

2014-11-27T11:21:59+00:00

commit d0aedcd4f14a22e23b313f42b7e6e6ebfc0fbc31 upstream.

vio_dring_avail() will allow use of every dring entry, but when the last
entry is allocated then dr->prod == dr->cons which is indistinguishable from
the ring empty condition. This causes the next allocation to reuse an entry.
When this happens in sunvdc, the server side vds driver begins nack'ing the
messages and ends up resetting the ldc channel. This problem does not effect
sunvnet since it checks for < 2.

The fix here is to just never allocate the very last dring slot so that full
and empty are not the same condition. The request start path was changed to
check for the ring being full a bit earlier, and to stop the blk_queue if
there is no space left. The blk_queue will be restarted once the ring is
only half full again. The number of ring entries was increased to 512 which
matches the sunvnet and Solaris vdc drivers, and greatly reduces the
frequency of hitting the ring full condition and the associated blk_queue
stop/starting. The checks in sunvent were adjusted to account for
vio_dring_avail() returning 1 less.

sunvnet: only use connected ports when sending

2014-07-29T00:29:53+00:00

The sunvnet driver doesn't check whether or not a port is connected when
transmitting packets, which results in failures if a port fails to connect
(e.g., due to a version mismatch). The original code also assumes
unnecessarily that the first port is up and a switch, even though there is
a flag for switch ports.

This patch only matches a port if it is connected, and otherwise uses the
switch_port flag to send the packet to a switch port that is up.

sunvnet: clean up objects created in vnet_new() on vnet_exit()

2014-07-17T05:44:07+00:00

Nothing cleans up the objects created by
vnet_new(), they are completely leaked.

vnet_exit(), after doing the vio_unregister_driver() to clean
up ports, should call a helper function that iterates over vnet_list
and cleans up those objects. This includes unregister_netdevice()
as well as free_netdev().

net: cassini: use nested lock annotation

2014-05-09T20:34:10+00:00

In the cas_lock_tx function we acquire multiple locks in a loop and
need to use nested lock annotation to prevent lockdep warnings.

sungem: Call dev_consume_skb_any instead of dev_kfree_skb.

2014-03-25T04:19:12+00:00

Replace dev_kfree_skb with dev_consume_skb_any in gem_tx which can be
called in hard irq and other contexts.  gem_tx handles successfully
transmitted packets.

niu: Use pci_enable_msix_range() instead of pci_enable_msix()

2014-02-18T20:33:34+00:00

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() and pci_enable_msix_range()
interfaces.

drivers/net: delete non-required instances of include

2014-01-16T19:53:26+00:00

None of these files are actually using any __init type directives
and hence don't need to include .   Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

This covers everything under drivers/net except for wireless, which
has been submitted separately.
