2010-02-19sfc: SFE4002/SFN4112F: Widen temperature and voltage tolerancesBen Hutchings
The temperature and voltage limits currently set on these boards are too conservative and will cause the driver to stop the net device erroneously in some systems. Based on a review of the chip datasheets and advice from the designer of these boards: - Raise the maximum board temperatures to the specified maximum ambient temperatures for their PHYs plus the expected temperature bias of the board - Raise the maximum controller temperature to 90 degrees - Lower the minimum temperatures to 0 degrees - Widen the voltage tolerances to at least +/- 10% Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2010-02-19sfc: Fix sign of efx_mcdi_poll_reboot() error in efx_mcdi_poll()Ben Hutchings
efx_mcdi_poll() uses positive error numbers, matching the MCDI protocol. It must negate the result of efx_mcdi_poll_reboot() which returns the usual negative error numbers. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-02-12sfc: Fix SFE4002 initialisationSteve Hodgson
From: Steve Hodgson <shodgson@solarflare.com> Commit 357d46a17e54c9a87e0e6ef3930ff4ab2d232b81 "sfc: QT202x: Remove unreliable MMD check at initialisation" broke initialisation of the SFE4002. efx_mdio_reset_mmd() returns a positive value rather than 0 on success. The above commit causes this value to be propagated up by qt202x_reset_phy(), which is treated as a failure by its callers. Change qt202x_reset_phy() to return 0 if successful. The PCI layer treats >0 as "fail, but please call remove() anyway", which means that unloading the driver would cause a crash. Add a WARN_ON() on the failure path of efx_pci_probe() to provide early warning if there are any other cases where we do this.

2010-02-03sfc: Replace PHY MDIO test with an 'alive' testBen Hutchings
SFC9000-family boards do not all use MDIO PHYs, so we need a different test for PHY aliveness. Introduce a PHY operation test_alive(). For PHYs attached to Falcon, use a common implementation based on the existing PHY MDIO test. For PHYs managed through MCDI, use the appropriate MCDI request. Change test name in ethtool from 'core mdio' to 'phy alive'. Rename test_results::mdio to phy_alive and test_results::phy to phy_ext.

2010-01-25sfc: Use fixed-size buffers for MCDI NVRAM requestsBen Hutchings
The low-level MCDI code always uses 32-bit MMIO operations, and callers must pad input and output buffers to multiples of 4 bytes. The MCDI NVRAM functions are not doing this. Also, their buffers are declared as variable-length arrays with no explicit maximum length. Switch to a fixed buffer size based on the chunk size used by the MTD driver (which is a multiple of 4).

2010-01-25sfc: Add workspace for GMAC bug workaround to MCDI MAC_STATS bufferGuido Barzini
Due to a hardware bug in the SFC9000 family, the firmware must transfer raw GMAC statistics to host memory before aggregating them into the cooked (speed-independent) MAC statistics. Extend the stats buffer to support this. The length of the buffer is explicit in the MAC_STATS command, so this change is backward-compatible on both sides.

2010-01-13sfc: Fix conditions for MDIO self-testBen Hutchings
The MDIO self-test should not be run on boards without an MDIO PHY, such as SFN5122F-R3 and later revisions. It should also not try to address a specific MMD in an MDIO clause 22 PHY.

2010-01-13sfc: Fix polling for slow MCDI operationsBen Hutchings
When the interface is down and we are using polled mode for MCDI operations, we busy-wait for completion for approximately 1 jiffy using udelay() and then back off to schedule(). But the completion will not wake the task, since we are using polled mode! We must use schedule_timeout_uninterruptible() instead.

2009-12-23sfc: QT2025C: Add error message for suspected bad SFP+ cablesBen Hutchings

2009-12-23sfc: QT2025C: Work around PHY firmware initialisation bugMatthew Slattery

2009-12-23sfc: QT2025C: Switch into self-configure mode when not in loopbackMatthew Slattery
The PHY boots in a mode which is not necessarily optimal. This change switches it to self-configure mode (except when in loopback, which won't work in that mode if an SFP+ module is not present) by rebooting the PHY's microcontroller, and replicating the sequence of configuration writes from the boot EEPROM with the appropriate changes.

2009-12-23sfc: QT2025C: Work around PHY bugMatthew Slattery

2009-12-23sfc: Include XGXS in XMAC link status check except in XGMII loopbackBen Hutchings
The XGXS block may not get a link immediately in XGXS or XAUI loopback modes, so we still need to check it. Split falcon_xaui_link_ok() into falcon_xgxs_link_ok(), which checks only the Falcon XGXS block, and falcon_xmac_link_ok(), which checks one or both sides of the link as appropriate. Also rename falcon_check_xaui_link() to falcon_xmac_link_ok_retry(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-12-23sfc: Move PHY software state initialisation from init() into probe()Steve Hodgson
This prevents efx->link_advertising from being blatted during a reset. The phy_short_reach sysfs node is now destroyed later in the port shutdown process, so check for STATE_RUNNING after acquiring the rtnl_lock (just like in set_phy_flash_cfg).

2009-12-13drivers/net/sfc: Correct code taking the size of a pointerJulia Lawall
The function efx_iterate_state contains the code memcpy(&payload->msg, payload_msg, sizeof(payload_msg)); This is the only use of payload_msg. The type of payload_msg is changed from a pointer to an array, so that the result of sizeof really is the length of the string.
