2009-11-30sfc: Refactor link configurationBen Hutchings1-0/+3
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>.

2009-04-30sfc: Use generic MDIO functions and definitionsBen Hutchings1-241/+40
Make use of the newly-added generic MDIO clause 45 support and remove redundant definitions. Add an 'efx_' prefix to the remaining driver-specific MDIO functions and remove arguments which are redundant with efx->mdio.prtad.

2009-03-02sfc: Fix reporting of PHY idBen Hutchings1-4/+4
Shuffle bits of the OUI into the conventional written order. Replace PHY id component macros with functions. Zero-pad PHY id components in log messages. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-31sfc: SFX7101/SFT9001: Fix AN advertisementsBen Hutchings1-1/+2
All 10Xpress PHYs require autonegotiation all the time; enforce this in the set_settings() method and do not treat it as a workaround. Remove claimed support for 100M HD mode since it is not supported by current firmware. Do not set speed override bits when AN is enabled, and do not use register 1.49192 for AN configuration as it can override what we set elsewhere. Always set the AN selector bits to 1 (802.3). Fix confusion between Next Page and Extended Next Page. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-13sfc: Add support for Solarflare 10Xpress SFT9001Ben Hutchings1-0/+8
Add type codes for the new PHY and rename the SFX7101 type code. Add definition of clause 22 extension MMD. Adapt the 10Xpress SFX7101 code to support the SFT9001 as well. Clean up register definitions. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-13sfc: Implement auto-negotiationBen Hutchings1-0/+32
Add infrastructure for auto-negotiation of speed, duplex and flow control. When using 10Xpress, auto-negotiate flow control. While we're at it, clean up the code to warn when partner is not 10GBASE-T capable. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-12-13sfc: Clean up MDIO flag settingBen Hutchings1-0/+4
We often want to set or clear a flag in an MDIO register, but avoid writing if no change is required since this can have side-effects. Encapsulate this in a function, mdio_clause45_set_flag().

2008-11-06sfc: Use lm87 and lm90 drivers for board temperature/power monitoringBen Hutchings1-0/+7
Add board monitoring to periodic work whenever link is down. For SFE4001, report when a fault has caused the PHY to turn off. For SFE4002, switch XFP PHY into low-power state in case of a fault. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
