2009-08-26sfc: Improve reliability of RX queue flushingBen Hutchings
Reconfiguring the port requires us to flush all DMA queues. In repeated testing we have found that RX flushes would sometimes fail because the RX DMA engine was not properly isolated from the MACs.

2009-08-26sfc: Work around XMAC bug causing packet loss with some peersBen Hutchings
Received frames must be re-clocked by the local XGXS to the 156.25 MHz (DDR) clock of the XGMII. If the remote clock is slightly faster this can reduce a minimum IPG of 64 bit-times (1 cycle) to 32 bit-times (half a cycle). If the XMAC detects that a frame has reached the maximum RX frame length in the same cycle that it receives one of these reduced IPGs, it may miss the IPG, causing two valid frames to be treated as a single invalid frame (over-length with bad CRC). We work around this by increasing the maximum RX frame length so that peers with matched MTU will not provoke this bug.

2009-08-26sfc: QT2025C: Use hard reset onlyBen Hutchings
At probe time, falcon_reset_hw() performs a hard reset of the PHY along with Falcon. There is no need to perform a soft reset later, and any access to standard MDIO registers before the PHY firmware has booted can interrupt the boot process, making the port unusable.

2009-08-26mdio: Check MDIO_STAT1_FAULT in mdio45_links_ok()Ben Hutchings
Some PHYs will report that the link is up even though there is a fault condition. Therefore, check the fault flag too. We must also read STAT2 to reset this flag. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-26sfc: Do not reinitialise XAUI serdes before it has completed resetBen Hutchings
falcon_reset_xaui() waits for XGXS reset to complete, but the XAUI serdes reset may take longer. It needs to check both reset active bits. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-08-26sfc: Fix ordering of device registration and initial netif_carrier_off()Ben Hutchings
We must call netif_carrier_off() after the device is registered, not before, to set the operational state and user-space IFF_RUNNING flag correctly. Since we don't want observers to see an intermediate state, open-code register_netdev() and add efx_update_name() and netif_carrier_off() into the locked region.

Broadcom's phys come in two distinctly different register layouts.

2009-08-26netxen: bridged mode optimizationsNarender Kumar
When the interface is put in bridged mode, destination mac addresses are unknown to firmware. So packets take a slow path (lower priority) in firmware reducing performance. Firmware can cache limited number of remote unicast mac addresses for certain interval, if "dynamic mac learning" mode is enabled. Driver needs to enable this "mac learning" mode in firmware. Currently this is done through net device class sysfs entry, possibly this can also be done upon netlink notifications to from bridge.
