2009-11-28sfc: Simplify PHY pollingSteve Hodgson1-42/+27
Falcon can generate events for LASI interrupts from the PHY, but in practice we have never implemented this in reference designs. Instead we have polled, inserted the appropriate events, and then handled the events later. This is a waste of time and code. Instead, make PHY poll functions update the link state synchronously and report whether it changed. We can still make use of the LASI registers as a shortcut on the SFT9001.

2009-11-26sfc: Split MAC stats DMA initiation and completionBen Hutchings1-2/+2
From: Steve Hodgson <shodgson@solarflare.com> Currently we initiate MAC stats DMA and busy-wait for completion when stats are requested. We can improve on this with a periodic timer to initiate and poll for stats, and opportunistically poll when stats are requested. Since efx_nic::stats_disable_count and efx_stats_{disable,enable}() are Falcon-specific, rename them and move them accordingly.

2009-11-26sfc: Clean up struct falcon_board and struct falcon_board_dataBen Hutchings1-1/+1

2009-11-24sfc: Make board information explicitly Falcon-specificBen Hutchings1-1/+1
Rename struct efx_board to struct falcon_board. Introduce and use inline function to look up board info from struct efx_nic, in preparation for moving it. Move board init and fini calls into NIC probe and remove functions. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-24sfc: Rename efx_board::init_leds to init_phy and use for SFN4111TBen Hutchings1-0/+2
efx_board::init_leds was introduced as a second stage of initialisation because of the inter-dependency between the board and PHY. We want to move board initialisation into NIC probing, which is too early to use MDIO, so SFN4111T initialisation also needs to be split.

2009-11-24sfc: Use a single blink implementationBen Hutchings1-8/+16
Only some PHYs have firmware support for a LED blink mode, so we currently blink the others in a timer function. Since all PHYs have simple on and off modes, we don't gain anything by using multiple blink implementations. Also, since we have a process context there is no need to use a timer.

Siena is still based on the Falcon hardware architecture and will share many of these definitions, so replace falcon_hwdefs.h with regs.h.

Commits 27fbc7d 'mdio: Expose pause frame advertising flags to ethtool' and c634263 'sfc: 10Xpress: Initialise pause advertising flags' added to our reported advertising flags. efx_mdio_set_settings() requires that all advertising flags are also present in the supported flags, so make sure that is true.

2009-01-30sfc: Replace stats_enabled flag with a disable countBen Hutchings1-6/+6
Currently we use a spin-lock to serialise statistics fetches and also to inhibit them for short periods of time, plus a flag to enable/disable statistics fetches for longer periods of time, during online reset. This was apparently insufficient to deal with the several reasons for stats being disabled. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2009-01-30sfc: SFX7101/SFT9001: Fix AN advertisementsBen Hutchings1-93/+58
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>
2009-01-30sfc: Reinitialise the PHY completely in case of a PHY or NIC resetSteve Hodgson1-0/+1
In particular, set pause advertising bits properly. A PHY reset is not necessary to recover from the register self-test, so use a "invisible" reset there instead. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-30sfc: SFT9001: Fix speed reporting in 1G PHY loopbackSteve Hodgson1-18/+9

2009-01-30sfc: SFX7101: Remove workaround for bad link trainingSteve Hodgson1-20/+0
Early versions of the SFX7101 firmware could complete link training in a state where it would not adequately cancel noise (Solarflare bug 10750). We previously worked around this by resetting the PHY after seeing many Ethernet CRC errors. This workaround is unsafe since it takes no account of the interval between errors; it also appears to be unnecessary with production firmware. Therefore remove it.

2009-01-21sfc: Replace LRO with GROHerbert Xu1-0/+1
This patch makes sfc invoke the GRO hooks instead of LRO. As GRO has a compatible external interface to LRO this is a very straightforward replacement. Everything should appear identical to the user except that the offload is now controlled by the GRO ethtool option instead of LRO. I've kept the lro module parameter as is since that's for compatibility only. I have eliminated efx_rx_mk_skb as the GRO layer can take care of all packets regardless of whether GRO is enabled or not. So the only case where we don't call GRO is if the packet checksum is absent. This is to keep the behaviour changes of the patch to a minimum.

The SFC4000 has a separate MAC for use at sub-10G speeds. Introduce an efx_mac_operations structure with implementations for the two MACs. Switch between the MACs as necessary.
