This adds support for the SFC9000 family of 10G Ethernet controllers and LAN-on-motherboard chips, starting with the SFL9021 'Siena' and SFC9020 'Bethpage'. The SFC9000 family is based on the SFC4000 'Falcon' architecture, but with some significant changes: - Two ports are associated with two independent PCI functions (except SFC9010) - Integrated 10GBASE-T PHY(s) (SFL9021/9022) - MAC, PHY and board peripherals are managed by firmware - Driver does not require board-specific code - Firmware supports wake-on-LAN and lights-out management through NC-SI - IPv6 checksum offload and RSS - Filtering by MAC address and VLAN (not included in this code) - PCI SR-IOV (not included in this code) Credit for this code is largely due to my colleagues at Solarflare: Guido Barzini Steve Hodgson Kieran Mansley Matthew Slattery Neil Turton Signed-off-by:

In new NICs flash is managed by firmware and we will use high-level operations on partitions rather than direct SPI commands. Add support for multiple MTD partitions per flash device and remove the direct link between MTD and SPI devices. Maintain a list of MTD partitions in struct efx_nic. Signed-off-by:

Refactor PHY, MAC and NIC configuration operations so that the existing link configuration can be re-pushed with: efx->phy_op->reconfigure(efx); efx->mac_op->reconfigure(efx); and a new configuration with: efx->nic_op->reconfigure_port(efx); (plus locking and error-checking). We have not held the link settings in software (aside from flow control), and have relied on asking the hardware what they are. This is a problem because in some cases the hardware may no longer be in a state to tell us. In particular, if an entire multi-port board is reset through one port, the driver bindings to other ports have no chance to save settings before recovering. We only actually need to keep track of the autonegotiation settings, so add an ethtool advertising mask to struct efx_nic, initialise it in PHY init and update it as necessary. Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and struct ethtool_cmd. Much of this was done by Steve Hodgson <shodgson@solarflare.com>. Signed-off-by: -

Pause frame generation is gated by both RX_XOFF_MAC_EN and an enable bit in each MAC. RX_XOFF_MAC_EN bit always reads back as 0 so we need to set it correctly every time we modify RX_CFG_REG. Simplify this by always setting it to 1 and only changing the enable bits in the MACs. Signed-off-by:

pktgen threads are bound to given CPU, we can allocate memory for these threads in a NUMA aware way. After a pktgen session on two threads, we can check flows memory was allocated on right node, instead of a not related one. # grep pktgen_thread_write /proc/vmallocinfo 0xffffc90007204000-0xffffc90007385000 1576960 pktgen_thread_write+0x3a4/0x6b0 [pktgen] pages=384 vmalloc N0=384 0xffffc90007386000-0xffffc90007507000 1576960 pktgen_thread_write+0x3a4/0x6b0 [pktgen] pages=384 vmalloc N1=384 Signed-off-by:

When retransmitting due to T3 timeout, retransmit all the in-flight chunks for the corresponding transport/path, including chunks sent less then 1 rto ago. This is the correct behaviour according to rfc4960 section 6.3.3 E3 and "Note: Any DATA chunks that were sent to the address for which the T3-rtx timer expired but did not fit in one MTU (rule E3 above) should be marked for retransmission and sent as soon as cwnd allows (normally, when a SACK arrives). ". This fixes problems when more then one path is present and the T3 retransmission of the first chunk that timeouts stops the T3 timer for the initial active path, leaving all the other in-flight chunks waiting forever or until a new chunk is transmitted on the same path and timeouts (and this will happen only if the cwnd allows sending new chunks, but since cwnd was dropped to MTU by the timeout => it will wait until the first heartbeat). Example: 10 packets in flight, sent at 0.1 s intervals on the primary path. The primary path is down and the first packet timeouts. The first packet is retransmitted on another path, the T3 timer for the primary path is stopped and cwnd is set to MTU. All the other 9 in-flight packets will not be retransmitted (unless more new packets are sent on the primary path which depend on cwnd allowing it, and even in this case the 9 packets will be retransmitted only after a new packet timeouts which even in the best case would be more then RTO). This commit reverts d0ce9291 and also removes the now unused transport->last_rto, introduced in b6157d8e. p.s The problem is not only when multiple paths are there. It can happen in a single homed environment. If the application stops sending data, it possible to have a hung association. Signed-off-by:
