All drivers that support modification of the RX flow hash indirection table initialise it in the same way: RX rings are assigned to table entries in rotation. Make that default policy explicit by having them call a ethtool_rxfh_indir_default() function. In the ethtool core, add support for a zero size value for ETHTOOL_SRXFHINDIR, which resets the table to this default.

Add a new ethtool operation (get_rxfh_indir_size) to get the indirectional table size. Use this to validate the user buffer size before calling get_rxfh_indir or set_rxfh_indir. Use get_rxnfc to get the number of RX rings, and validate the contents of the new indirection table before calling set_rxfh_indir. Remove this validation from drivers.

Correct the description of ethtool_rxnfc::rule_locs; it is an array of currently used locations, not all possible valid locations. Add note that drivers must not use ethtool_rxnfc::rule_locs. The rule_locs argument to ethtool_ops::get_rxnfc is either NULL or a pointer to an array of u32, so change the parameter type accordingly.

The vmxnet3 driver enables vlan filters if filtering is enabled for any vlan. In promiscuous mode the filter table is cleared to in order to disable filtering. However, if a vlan device is subsequently created that vlan will be added to the filter, re-engaging it. As a result, not only do we not see all the vlans in promiscuous mode, we don't even see vlans for which a filter was previously created. CC: Scott J.

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: NScott J.

When receiving packets from another guest on the same hypervisor, it's generally possible to receive large packets because no segmentation is necessary and these packets are handled by LRO. However, when doing routing or bridging we must disable LRO and lose this benefit. In these cases GRO can still be used and it is very effective because the packets which are segmented in the hypervisor are received very close together and can easily be merged.

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 a0d2730c "net: vmxnet3: convert to hw_features". Patch applies to 2.6.37 / 2.6.38 and 2.6.39-rc6. Please CC: comments.

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.

Using the vmxnet3 driver produces a lockdep warning because vmxnet3_set_mc(), which is called with mc->mca_lock held, takes adapter->cmd_lock. 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. Tested: make allyesconfig on x86_64 + e1000e/bnx2x work Signed-off-by: NDavid Decotigny <decot@google.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

After commit d5dbda23 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. 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). Tested with modified (to reproduce this bug) myri10ge driver. Cc: stable@kernel.org # 2.6.37+ Signed-off-by: NStanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: NDavid S.

There is a small possibility of a race where the suspend routine gets called, while a napi callback is still pending and when that comes up, it enables interrupts which just got disabled in the suspend routine. This change adds napi disable call in suspend and enable in resume to avoid race.

This is a performance enhancement fix. vmxnet3 device performs better when provided with at least 54 bytes (ethernet 14 + IP 20+ TCP 20) in the first SG buffer.

Some drivers are using skb_transport_offset(skb) instead of skb->csum_start for NETIF_F_HW_CSUM offload. This does not matter now, but if someone implements checksumming of encapsulated packets then this will break silently. TSO output paths are left as they are, since they are for IP+TCP only (might be worth converting though). Signed-off-by: NMichał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: NDavid S.
