sfc: Replace stats_enabled flag with a disable count

2009-01-30T22:06:33+00:00

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.

sfc: SFX7101/SFT9001: Fix AN advertisements

2009-01-30T22:06:32+00:00

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.

sfc: SFT9001: Always enable XNP exchange on SFT9001 rev B

2009-01-30T22:06:32+00:00

This workaround is not specific to rev A.

sfc: Test for PHYXS faults whenever we cannot test link state bits

2009-01-30T22:06:31+00:00

Depending on the loopback mode, there may be no pertinent link state
bits.  In this case we test the PHYXS RX fault bit instead.  Make
sure to do this in all cases where there are no link state bits.

sfc: Reinitialise the PHY completely in case of a PHY or NIC reset

2009-01-30T22:06:30+00:00

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.

sfc: Fix post-reset MAC selection

2009-01-30T22:06:30+00:00

Modify falcon_switch_mac() to always set NIC_STAT_REG, even if the the
MAC is the same as it was before.  This ensures that the value is
correct after an online reset.

sfc: SFN4111T: Fix GPIO sharing between I2C and FLASH_CFG_1

2009-01-30T22:06:29+00:00

Change sfn4111t_reset() to change only GPIO output enables so that it
doesn't break subsequent I2C operations.

Update comments to explain exactly what we're doing.

Add a short sleep to make sure the FLASH_CFG_1 value is latched before
any subsequent I2C operations.

sfc: SFT9001: Fix speed reporting in 1G PHY loopback

2009-01-30T22:06:29+00:00

Instead of disabling AN in loopback, just prevent restarting AN and
override the speed in sft9001_get_settings().

sfc: SFX7101: Remove workaround for bad link training

2009-01-30T22:06:27+00:00

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.
