2011-10-07igb: Use node specific allocations for the q_vectors and ringsAlexander Duyck2-5/+79
This change is meant to update the ring and vector allocations so that they are per node instead of allocating everything on the node that ifconfig/modprobe is called on. By doing this we can cut down significantly on cross node traffic.

2011-10-07igb: push data into first igb_tx_buffer sooner to reduce stack usageAlexander Duyck2-50/+54
Instead of storing most of the data for the TX hot path in the stack until we are ready to write the descriptor we can save ourselves some time and effort by pushing the SKB, tx_flags, gso_size, bytecount, and protocol into the first igb_tx_buffer since that is where we will end up putting it anyway.

2011-10-07igb: consolidate creation of Tx buffer info and data descriptorAlexander Duyck2-142/+184
This change will combine the writes of tx_buffer_info and the Tx data descriptors into a single function.

2011-10-06igb: Make first and tx_buffer_info->next_to_watch into pointersAlexander Duyck2-31/+37
This change converts two tx_buffer_info index values into pointers. The advantage to this is that we reduce unnecessary computations and in the case of next_to_watch we get an added bonus of the value being able to provide additional information as a NULL value indicates it is unset versus a 0 not having any meaning for the index value.

2011-10-06igb: Consolidate creation of Tx context descriptors into a single functionAlexander Duyck1-127/+106
This patch is meant to simplify the transmit path by reducing the overhead for creating a transmit context descriptor. The current implementation is split with igb_tso and igb_tx_csum doing two separate implementations on how to setup the tx_buffer_info structure and the tx_desc. By combining them it is possible to reduce code and simplify things since now only one function will create context descriptors.

2011-10-06igb: split buffer_info into tx_buffer_info and rx_buffer_infoAlexander Duyck3-88/+92
In order to be able to improve the performance of the TX path it has been necessary to add addition info to the tx_buffer_info structure. However a side effect is that the structure has gotten larger and this in turn has also increased the size of the RX buffer info structure. In order to avoid this in the future I am splitting the single buffer_info structure into two separate ones and instead I will join them by making the buffer_info pointer in the ring a union of the two.

2011-10-06bridge: allow forwarding some link local framesstephen hemminger4-5/+71
This is based on an earlier patch by Nick Carter with comments by David Lamparter but with some refinements. Thanks for their patience this is a confusing area with overlap of standards, user requirements, and compatibility with earlier releases. It adds a new sysfs attribute /sys/class/net/brX/bridge/group_fwd_mask that controls forwarding of frames with address of: 01-80-C2-00-00-0X The default setting has no forwarding to retain compatibility. One change from earlier releases is that forwarding of group addresses is not dependent on STP being enabled or disabled. This choice was made based on interpretation of tie 802.1 standards. I expect complaints will arise because of this, but better to follow the standard than continue acting incorrectly by default. The filtering mask is writeable, but only values that don't forward known control frames are allowed. It intentionally blocks attempts to filter control protocols. For example: writing a 8 allows forwarding 802.1X PAE addresses which is the most common request.

2011-10-05xen: netback: convert to SKB paged frag API.Ian Campbell1-21/+33
netback currently uses frag->page to store a temporary index reference while processing incoming requests. Since frag->page is to become opaque switch instead to using page_offset. Add a wrapper to tidy this up and propagate the fact that the indexes are only u16 through the code (this was already true in practice but unsigned long and in were inconsistently used as variable and parameter types) Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Cc: Ian Campbell <ian.campbell@citrix.com> Cc: xen-devel@lists.xensource.com Cc: netdev@vger.kernel.org Signed-off-by: David S.

2011-10-05ixgbe: get pauseparam autonegMika Lansirinne1-7/+1
There is a problem in the ixgbe driver with the reporting of the flow control parameters. The autoneg parameter is shown to be of if *either* it really is off, or current modes for both tx and rx are off. The problem is seen when the parameters are read or set when the link is down. In this case, the driver sees that tx and rx are currently off and therefore autoneg parameter is incorrectly reported to be off too. Also, the ethtool binary can not set the autoneg off since it sees that it already is. When a link later comes up, the autonegotiation is carried out normally and the driver later on reports the autoneg parameter to be on (as it is) and then it can also be changed with ethtool. The patch is made against v3.0 kernel, but the problem seems to be there since v2.6.30-rc1. Reviewer comments: What we are trying to do is to disable flow control while the cable is disconnected. Since ixgbe defaults to full flow control, we call ethtool -A autoneg off rx off tx off while the cable is disconnected. This doesn't work, because the driver sets hw->fc.current_mode = ixgbe_fc_none if the cable is unplugged. ixgbe_get_pauseparam() then reports to ethtool that nothing needs to be done. The code fixes this, but it might have some unknown consequences.
