* vmxnet3: round down # of queues to power of twoShreyas Bhatewara2011-07-072-2/+6
| | | | | | | | | | vmxnet3 device supports only power-of-two number of queues. The driver therefore needs to check this and rounds down the number of queues to the nearest power of two.

* vmxnet3: fix starving rx ring whenoc_skb kb failsShreyas Bhatewara2011-07-052-43/+96
| | | | | | | | | | | | | | | | If the rx ring is completely empty, then the device may never fire an rx interrupt. Unfortunately, the rx interrupt is what triggers populating the rx ring with fresh buffers, so this will cause networking to lock up. This patch replenishes the skb in recv descriptor as soon as it is peeled off while processing rx completions. If the skb/buffer allocation fails, existing one is recycled and the packet in hand is dropped. This way none of the RX desc is ever left empty, thus avoiding starvation Signed-off-by: Scott J.

| * vmxnet3: Fix inconsistent LRO state after initializationThomas Jarosch2011-05-161-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During initialization of vmxnet3, the state of LRO gets out of sync with netdev->features. This leads to very poor TCP performance in a IP forwarding setup and is hitting many VMware users. Simplified call sequence: 1. vmxnet3_declare_features() initializes "adapter->lro" to true. 2. The kernel automatically disables LRO if IP forwarding is enabled, so vmxnet3_set_flags() gets called. This also updates netdev->features. 3. Now vmxnet3_setup_driver_shared() is called. "adapter->lro" is still set to true and LRO gets enabled again, even though netdev->features shows it's disabled. Fix it by updating "adapter->lro", too. The private vmxnet3 adapter flags are scheduled for removal in net-next, see commit a0d2730c9571aeba793cb5d3009094ee1d8fda35 "net: vmxnet3: convert to hw_features". Patch applies to 2.6.37 / 2.6.38 and 2.6.39-rc6. Please CC: comments.

* | vmxnet3: Use single tx queue when CONFIG_PCI_MSI not definedShreyas Bhatewara2011-05-122-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Resending this patch with few changes. Avoid multiple queues when MSI or MSI-X not available Limit number of Tx queues to 1 if MSI/MSI-X support is not configured in the kernel. This will make number of tx and rx queues equal when MSI/X is not configured thus providing better performance.

However, there are a couple of places where adapter->cmd_lock is taken with softirqs enabled, lockdep warns that a softirq that tries to take mc->mca_lock could happen while adapter->cmd_lock is held, leading to an AB-BA deadlock. I'm not sure if this is a real potential deadlock or not, but the simplest and best fix seems to be simply to make sure we take cmd_lock with spin_lock_irqsave() everywhere -- the places with plain spin_lock just look like oversights. The full enormous lockdep warning is: ========================================================= [ INFO: possible irq lock inversion dependency detected ] 2.6.39-rc6+ #1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated.

Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem).

* vmxnet3: Remove incorrect implementation of ethtool_ops::get_flags()Ben Hutchings2010-06-301-7/+1
| | | | | | | | | Only some netdev feature flags correspond directly to ethtool feature flags. ethtool_op_get_flags() does the right thing. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Bhavesh Davda <bhavesh@vmware.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* drivers/net/vmxnet3: Use kzallocJulia Lawall2010-05-171-2/+1
| | | | | | | | | | | | | | | | | | | | | | | Use kzalloc rather than the combination of kmalloc and memset. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,size,flags; statement S; @@ -x = kmalloc(size,flags); +x = kzalloc(size,flags); if (x == NULL) S -memset(x, 0, size); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Bhavesh Davda <bhavesh@vmware.com> Signed-off-by: David S.

* net: trans_start cleanupsEric Dumazet2010-05-101-1/+0
| | | | | | | | | | | 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 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* net: convert multicast list to list_headJiri Pirko2010-04-031-3/+3
| | | | | | | | | | | | | Converts the list and the core manipulating with it to be the same as uc_list. +uses two functions for adding/removing mc address (normal and "global" variant) instead of a function parameter. +removes dev_mcast.c completely. +exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for manipulation with lists on a sandbox (used in bonding and 80211 drivers) Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S.

| | | | | | | | | | | This patch replaces dev->mc_count in all drivers (hopefully I didn't miss anything). Used spatch and did small tweaks and conding style changes when it was suitable. Jirka Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
