2015-01-24vxlan: Eliminate dependency on UDP socket in transmit pathTom Herbert3-41/+38
In the vxlan transmit path there is no need to reference the socket for a tunnel which is needed for the receive side. We do, however, need the vxlan_dev flags. This patch eliminate references to the socket in the transmit path, and changes VXLAN_F_UNSHAREABLE to be VXLAN_F_RCV_FLAGS. This mask is used to store the flags applicable to receive (GBP, CSUM6_RX, and REMCSUM_RX) in the vxlan_sock flags. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S.

2015-01-24udp: Do not require sock in udp_tunnel_xmit_skbTom Herbert5-26/+29
The UDP tunnel transmit functions udp_tunnel_xmit_skb and udp_tunnel6_xmit_skb include a socket argument. The socket being passed to the functions (from VXLAN) is a UDP created for receive side. The only thing that the socket is used for in the transmit functions is to get the setting for checksum (enabled or zero). This patch removes the argument and and adds a nocheck argument for checksum setting. This eliminates the unnecessary dependency on a UDP socket for UDP tunnel transmit.

2015-01-23xen-netback: always fully coalesce guest Rx packetsDavid Vrabel2-105/+3
Always fully coalesce guest Rx packets into the minimum number of ring slots. Reducing the number of slots per packet has significant performance benefits when receiving off-host traffic. Results from XenServer's performance benchmarks: Baseline Full coalesce Interhost VM receive 7.2 Gb/s 11 Gb/s Interhost aggregate 24 Gb/s 24 Gb/s Intrahost single stream 14 Gb/s 14 Gb/s Intrahost aggregate 34 Gb/s 34 Gb/s However, this can increase the number of grant ops per packet which decreases performance of backend (dom0) to VM traffic (by ~10%) /unless/ grant copy has been optimized for adjacent ops with the same source or destination (see "grant-table: defer releasing pages acquired in a grant copy"[1] expected in Xen 4.6).

2015-01-22igb: Indicate failure on vf reset for empty mac addressAlexander Graf1-2/+6
Commit 5ac6f91d changed the igb driver to expose a zero (empty) mac address to the VF on reset rather than a random one. However, that behavioral change also requires igbvf driver changes which can be hard especially when we want to talk to proprietary guest OSs. Looking at the code previous to the commit in Linux that made igbvf work with empty mac addresses (8d56b6d), we can see that on reset failure the driver will try to generate a new mac address with both the old and the new code. Furthermore, ixgbe does send reset failure when it detects an empty mac address (35055928c). So I think it's safe to make igb behave the same. With this patch I can successfully run a Windows 8.1 guest with an empty mac address and an assigned igbvf device that has no mac address set by the host. If anyone is aware of a guest driver that chokes on NACK returns of VF RESET commands, please speak up.

2015-01-22igb: refactor time sync interrupt handlingRichard Cochran1-30/+19
The code that handles the time sync interrupt is repeated in three different places. This patch refactors the identical code blocks into a single helper function.

2015-01-22fm10k: Clean-up page reuse codeAlexander Duyck1-17/+17
This patch cleans up the page reuse code getting it into a state where all the workarounds needed are in place as well as cleaning up a few minor oversights such as using __free_pages instead of put_page to drop a locally allocated page. It also cleans up how we clear the descriptor status bits. Previously they were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a 64 bit field and 64 bit writes can be a bit more expensive on on 32 bit systems. Since we are no longer using the header split feature the upper 32 bits of the address no longer need to be cleared. As a result we can just clear the status bits and leave the length and VLAN fields as-is which should provide more information in debugging.
