This integrates support for the SFC9000 family of 10G Ethernet controllers and LAN-on-motherboard chips, starting with the SFL9021 'Siena' and SFC9020 'Bethpage'.

2009-11-29sfc: Add support for SFC9000 family (1)Ben Hutchings5-0/+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.

2009-11-29sfc: Extend MTD driver for use with new NICsBen Hutchings6-124/+255
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.

2009-11-29sfc: Remove static PHY data and enumerationsBen Hutchings9-65/+95

2009-11-29sfc: Refactor link configurationBen Hutchings15-182/+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>.

2009-11-29sfc: Turn pause frame generation on and off at the MAC, not the RX FIFOBen Hutchings2-8/+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. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Flow Control autoneg should be disabled for certain adapters that don't support autonegotiation of Flow Control at 10 gigabit. These interfaces are the 10GBASE-T devices, CX4, and SFP+, all running at 10 gigabit only. 1 gigabit is fine.

2009-11-29ixgbe: handle parameters for tx and rx EITR, no div0Shannon Nelson1-6/+7
