* sfc: Add support for SFC9000 family (1)Ben Hutchings2009-11-305-0/+2595
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

* sfc: Refactor link configurationBen Hutchings2009-11-3015-182/+273
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>.

* sfc: Turn pause frame generation on and off at the MAC, not the RX FIFOBen Hutchings2009-11-302-8/+8
| | | | | | | | | | 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.

| * sctp: on T3_RTX retransmit all the in-flight chunksAndrei Pelinescu-Onciul2009-11-294-15/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 d0ce92910bc04e107b2f3f2048f07e94f570035d and also removes the now unused transport->last_rto, introduced in b6157d8e03e1e780660a328f7183bcbfa4a93a19. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When mac80211 resumes, it currently first sets suspended to false so the driver can start doing things and we can receive frames. However, if we actually receive frames then it can end up starting some work which adds timers and then later runs into a BUG_ON in the timer code because it tries add_timer() on a pending timer. Fix this by keeping track of the resuming process by introducing a new variable 'resuming' which gets set to true early on instead of setting 'suspended' to false, and allow queueing work but not receiving frames while resuming.

Linus pointed out that del_timer_sync() isn't actually needed if we make the timer able to deal with no longer being needed when it gets queued _while_ we're in the locked section that also deletes it. For that the timer function only needs to check the HT_ADDBA_RECEIVED_MSK bit as well as the HT_ADDBA_REQUESTED_MSK bit, only if the former is clear should it do anything.

In ALB/TAL mode, bonding driver calls set_mac for all slave with bond mac address. But bonding driver set netdev->dev_addr field to its original value, after enslaving interfaces. When ever active slave changes, it swap dev_addr of inactive slave with active. Yet it doesn't notify driver about change in netdev->dev_addr. As netxen driver need to set mac addr when ever interface comes up, it can't rely on netdev->dev_addr field. Specially in case of bonding mode ALB/TLB.
