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: 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: 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.

net: sfc: Use pci_clear_master() to disable bus mastering

2009-01-07T19:13:24+00:00

pci_disable_device() disables many features, like MSI-X, which we
never reenable in efx_reset().  Further, calls to pci_enable_device()
and pci_disable_device() must be matched since the nesting count was
introduced, so switch to using pci_clear_master() instead.

sfc: Use kzalloc() to ensure struct efx_spi_device is fully initialised

2008-12-13T06:08:50+00:00

Currently the mtd field is not initialised early enough.

sfc: Use model numbers for PHY type names

2008-12-13T06:06:54+00:00

Some of the PHY type names are overly generic.  Change them to include
the model numbers of the PHYs they represent.

Correct the model number reference at the top of xfp_phy.c.

sfc: Rework MAC, PHY and board event handling

2008-12-13T05:59:24+00:00

From: Steve Hodgson 

MAC, PHY and board events may be separately enabled and signalled.
Our current arrangement of chaining the polling functions can result
in events being missed.  Change them to be more independent.
