2012-10-22ixgbe: (PTP) refactor init, cyclecounter and resetJacob Keller3-73/+66
This patch modifies when and where PTP registers and data are set. Previously a work-around was used inside cyclecounter_start in order to reset some of the time registers. This patch creates a new ixgbe_ptp_reset specifically for this purpose. The cyclecounter configuration has trimmed down to only modify what is necessary. Due to hardware conditions after probe and before open, PTP init has now moved into the ixgbe_open call. This allows the ptp device name in the sysfs to be the ethernet device name instead of the MAC address. The cyclecounter check flag is renamed to PTP_ENABLED and is used to prevent PTP init from happening when PTP has not been enabled.

It is necessary to track the default user priority in the PF so that we can force it upon the VFs. The motivation behind this is to keep the VFs from getting access to user priorities meant for things like storage.

2012-10-22ixgbe: Add support for IPv6 and UDP to ixgbe_get_headlenAlexander Duyck1-1/+14
This change adds support for IPv6 and UDP to ixgbe_get_headlen. The advantage to this is that we can now handle ipv4/UDP, ipv6/TCP, and ipv6/UDP with a single memcpy instead of having to do them in multiple pskb_may_pull calls. A quick bit of testing shows that we increase throughput for a single session of netperf from 8800Mpbs to about 9300Mpbs in the case of ipv6/TCP. As such overall ipv6 performance should improve with this change.

This change allows us to add a mailbox versioning API. This will allow us to determine the features supported by the VFs from the PF. For example we will be implementing a version 1.1 API for the VF that will indicate that it can support us enabling Jumbo frames as the VF will support buffer chaining.

2012-10-19ixgbe: Enable jumbo frames support w/ SR-IOVAlexander Duyck3-31/+93
This change makes it so that we can have limited support for jumbo frames when SR-IOV is enabled. In order to accomplish this it is necessary to disable all VFs when the PF has jumbo frames enabled. If the VFs then request the same maximum frame size as the PF they will be re-enabled. A follow on patch will add a means of identifying when a VF can support spanning buffers and does not need to be worried about the actual supported max frame size.

2012-10-19ixgbe: Initialize q_vector cpu and affinity masks correctlyAlexander Duyck1-2/+5
When enabling DCB the rings belonging to a q_vector on CPU 0 were not reinitializing their DCA registers. Upon closer inspection the issue was that the q_vector CPU variable was left at 0 resulting in the driver not updating the DCA registers. In order to guarantee the DCA registers will be updated I am adding a couple line change so that we initialize the CPU variable to -1 which will force a DCA update the first time an interrupt fires on that q_vector. In addition we were setting the CPU affinity hint to all CPUs when we were not specifying a CPU. Instead we should leave it as all zeros to avoid any possible confusion about the fact that we shouldn't be giving a hint.

2012-10-09ixgbe/ixgbevf: Limit maximum jumbo frame size to 9.5K to avoid Tx hangsAlexander Duyck1-1/+1
This change limits the PF/VF driver to 9.5K max jumbo frame size in order prevent a possible Tx hang in the adapter when sending frames between pools. All of the parts in ixgbe support a maximum frame of 15.5K for standard traffic, however with SR-IOV or DCB enabled they should be limiting the MTU size to 9.5K. Instead of adding extra checks which would have to change the MTU when we go into or out of these modes it is preferred to just use a standard 9.5K MTU limit for all modes so that this extra overhead can be avoided.

Pull networking changes from David Miller: 1) GRE now works over ipv6, from Dmitry Kozlov. 2) Make SCTP more network namespace aware, from Eric Biederman. 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko. 4) Make openvswitch network namespace aware, from Pravin B Shelar. 5) IPV6 NAT implementation, from Patrick McHardy. 6) Server side support for TCP Fast Open, from Jerry Chu and others. 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel Borkmann. 8) Increate the loopback default MTU to 64K, from Eric Dumazet. 9) Use a per-task rather than per-socket page fragment allocator for outgoing networking traffic. This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around. Fix up various fairly trivial conflicts, mostly caused by the user namespace changes. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1012 commits) hyperv: Add buffer for extended info after the RNDIS response message. hyperv: Report actual status in receive completion packet hyperv: Remove extra allocated space for recv_pkt_list elements hyperv: Fix page buffer handling in rndis_filter_send_request() hyperv: Fix the missing return value in rndis_filter_set_packet_filter() hyperv: Fix the max_xfer_size in RNDIS initialization vxlan: put UDP socket in correct namespace vxlan: Depend on CONFIG_INET sfc: Fix the reported priorities of different filter types sfc: Remove EFX_FILTER_FLAG_RX_OVERRIDE_IP sfc: Fix loopback self-test with separate_tx_channels=1 sfc: Fix MCDI structure field lookup sfc: Add parentheses around use of bitfield macro arguments sfc: Fix null function pointer in efx_sriov_channel_type vxlan: virtual extensible lan igmp: export symbol ip_mc_leave_group netlink: add attributes to fdb interface tg3: unconditionally select HWMON support when tg3 is enabled.

This change makes it so that if only the first 256 bytes of a buffer are used we just copy the data out and leave the offset and page count unchanged. There are multiple advantages to this. First it allows us to reuse the page much more in the case of pages larger than 4K. It also allows us to avoid some expensive atomic operations in the form of get_page/put_page. In perf I have seen CPU utilization for put_page drop from 3.5% to 1.8% as a result of this patch when doing small packet routing, and packet rates increased by about 3%.

2012-08-16ixgbe: Only use double buffering if page size is less than 8KAlexander Duyck2-19/+45
This change makes it so that we do not use double buffering if the page size is larger than 4K. Instead we will simply walk through the page using up to 3K per receive, and if we receive less than we only move the offset by that amount. We will free the page when there is no longer any space left that we can use instead of checking the page count to see if we can cycle back to the start. The main motivation behind this is to avoid the unnecessary truesize cost for using a half page when most packets are 2K or smaller. With this new approach the largest possible truesize for a page fragment will be 3K when PAGE_SIZE is larger than 4K.

This change reverts an earlier patch that introduced ixgbe_init_rx_page_offset. The idea behind the function was to provide some variation in the starting offset for the page in order to reduce hot-spots in the cache. However it doesn't appear to provide any significant benefit in the testing I have done. It has however been a source of several bugs, and it blocks us from being able to use 2K fragments on larger page sizes. So the decision I made was to remove it.

2012-07-31netvm: propagate page->pfmemalloc from skb_alloc_page to skbMel Gorman1-2/+2
The skb->pfmemalloc flag gets set to true iff during the slab allocation of data in __alloc_skb that the the PFMEMALLOC reserves were used. If page splitting is used, it is possible that pages will be allocated from the PFMEMALLOC reserve without propagating this information to the skb. This patch propagates page->pfmemalloc from pages allocated for fragments to the skb. It works by reintroducing and expanding the skb_alloc_page() API to take an skb. If the page was allocated from pfmemalloc reserves, it is automatically copied. If the driver allocates the page before the skb, it should call skb_propagate_pfmemalloc() after the skb is allocated to ensure the flag is copied properly. Failure to do so is not critical. The resulting driver may perform slower if it is used for swap-over-NBD or swap-over-NFS but it should not result in failure.
