* openvswitch: Add SCTP supportJoe Stringer2013-08-26
| | | | | | | | | | | | | | | This patch adds support for rewriting SCTP src,dst ports similar to the functionality already available for TCP/UDP. Rewriting SCTP ports is expensive due to double-recalculation of the SCTP checksums; this is performed to ensure that packets traversing OVS with invalid checksums will continue to the destination with any checksum corruption intact.

* openvswitch: Mega flow implementationAndy Zhou2013-08-23
| | | | | | | | | | | | | | | | | | Add wildcarded flow support in kernel datapath. Wildcarded flow can improve OVS flow set up performance by avoid sending matching new flows to the user space program. The exact performance boost will largely dependent on wildcarded flow hit rate. In case all new flows hits wildcard flows, the flow set up rate is within 5% of that of linux bridge module. Pravin has made significant contributions to this patch. Including API clean ups and bug fixes. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: Andy Zhou <azhou@nicira.com> Signed-off-by: Jesse Gross <jesse@nicira.com>

* | | tcp: increase throughput when reordering is highYuchung Cheng2013-08-22

However the throughput is sub-optimal under high reordering because cwnd is increased only if the data is deliverd in order. I.e., FLAG_DATA_ACKED check in tcp_ack(). The more packet are reordered the worse the throughput is. Therefore when reordering is proven high, cwnd should advance whenever the data is delivered regardless of its ordering. If reordering is low, conservatively advance cwnd only on ordered deliveries in Open state, and retain cwnd in Disordered state (RFC5681). Using netperf on a qdisc setup of 20Mbps BW and random RTT from 45ms to 55ms (for reordering effect). This change increases TCP throughput by 20 - 25% to near bottleneck BW. A special case is the stretched ACK with new SACK and/or ECE mark. For example, a receiver may receive an out of order or ECN packet with unacked data buffered because of LRO or delayed ACK. The principle on such an ACK is to advance cwnd on the cummulative acked part first, then reduce cwnd in tcp_fastretrans_alert().

Akeem provides 3 igb patches, the first resets the link when EEE is enabled or disabled if the link is up. His second patch changes a register read which normally stores of the read value to "just-read" so that hardware can accurately latch the register read. Lastly, he adds rcu_lock to avoid a possible race condition with igb_update_stats function. Mitch provides a fix for SR-IOV, where MSI-X interrupts are required, so make sure that MSI-X is enabled before allowing the user to turn on SR-IOV. Alex's igb patch make it so that we limit the lower bound for max_frame_size to the size of a standard Ethernet frame. This allows for feature parity with other Intel based drivers such as ixgbe. Carolyn adds a SKU for a flashless i210 device and a fix for get_fw_version() so that it works for all parts for igb. In addition, she has 2 igb patches to refactor NVM code to accommodate devices with no flash. Lastly, she adds code to check for the failure of pci_disable_link_state() to attempt to work around a problem found with some systems. Laura provides the remaining 2 igb patches. One removing the hard-coded value for the size of the RETA indirection table, and creates a macro instead for the RETA indirection table. The second adds the ethtool callbacks necessary to change the RETA indirection table from userspace. Bruce fixes a whitespace issue in a recent commit and resolves a jiffies comparison warning by using time_after(). Li provides a fix for e1000e to avoid a kernel crash on shutdown by adding one more check in e1000e_shutdown(). This is due to e1000e_shutdown() trying to clear correctable errors on the upstream P2P bridge, when under some cases we do not have the upstream P2P bridge. v2: - fixed patch 11 conditional statement from < to <= based on feedback from Ben Hutchings - fixed patch 12 patch description (adding the commit summary) based on feedback from Sergei Shtylyov ==================== Signed-off-by: David S.

In order to achieve this, we add the indirection table field (rss_indir_tbl) in the board specific data structure (struct igb_adapter) to preserve the values across hardware resets. The indirection table must be initialized with default values in the following cases: * at module init time * when the number of RX queues changes. For this reason we add a new field (rss_indir_tbl_init) in igb_adapter that keeps track of the number of RX queues. Whenever the number of RX queues changes, the rss_indir_tbl is modified and initialized with default values. The rss_indir_tbl_init is updated accordingly.

| * | igb: Update MTU so that it is always at least a standard frame sizeAlexander Duyck2013-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes it so that we limit the lower bound for max_frame_size to the size of a standard Ethernet frame. This allows for feature parity with other Intel based drivers such as ixgbe.
