2009-10-29sfc: Enable heuristic selection between page and skb RX buffersBen Hutchings
Now that we can tell whether GRO is being applied, this heuristic is effective once more. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-29sfc: Feed GRO result into RX allocation policy and interrupt moderationBen Hutchings
When GRO is successfully merging received packets, we should allocate raw page buffers rather than skbs that will be discarded by GRO. Otherwise, we should allocate skbs. GRO also benefits from higher interrupt moderation, so increase the score for mergeable RX packets. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2009-10-28sfc: Set ip_summed correctly for page buffers passed to GROBen Hutchings
Page buffers containing packets with an incorrect checksum or using a protocol not handled by hardware checksum offload were previously not passed to LRO. The conversion to GRO changed this, but did not set the ip_summed value accordingly. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-28sfc: Really allow RX checksum offload to be disabledBen Hutchings
We have never checked the efx_nic::rx_checksum_enabled flag everywhere we should, and since the switch to GRO we don't check it anywhere. It's simplest to check it in the one place where we initialise the per-packet checksummed flag. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-24sfc: Rename 'xfp' file and functions to reflect realityBen Hutchings
The 'XFP' driver is really a driver for the QT2022C2 and QT2025C PHYs, covering both more and less than XFP. Rename its functions and constants to reflect reality and to reduce namespace pollution when sfc is a built-in driver. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-24sfc: Remove unused code for non-autoneg speed/duplex switchingBen Hutchings
The only multi-speed PHY driver using this is 10Xpress, and it does not support non-autoneg operation. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-24sfc: Merge efx_fc_resolve() into efx_mdio_get_pause()Ben Hutchings
efx_fc_resolve() is specific to MDIO and is not used by any other function. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-24sfc: Move MTD probe after netdev registration and name allocationBen Hutchings
The MTD partition is named based on the netdev name, which is set to 'eth%d' before registration. Also, the MTD partition will currently be left registered if netdev registration fails. Fix both these problems by moving the MTD probe after netdev registration. Hold the RTNL to serialise this with the netdev notifier that calls efx_mtd_rename().

2009-10-24sfc: Merge falcon_probe_phy() into falcon_probe_port()Ben Hutchings
MAC and PHY probing are bound up together, as evidenced by the initialisation of efx_nic::loopback_modes. Remove the current arbitrary separation. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-10-24sfc: Change order of device removal to reverse of probe orderBen Hutchings
This makes efx_pci_remove_main() more obviously the inverse of efx_pci_probe_main(), and matches our out-of-tree driver. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-10-24sfc: Move all TX DMA length limiting into tx.cBen Hutchings
Replace the duplicated logic in efx_enqueue_skb() and efx_tx_queue_insert() with an inline function, efx_max_tx_len(). Remove the failed attempt at abstracting hardware-specifics and put all the magic numbers in efx_max_tx_len(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2009-10-24sfc: Rename register I/O header and functions used by both Falcon and SienaBen Hutchings

2009-10-24sfc: Update hardware definitions for SienaBen Hutchings
Siena is still based on the Falcon hardware architecture and will share many of these definitions, so replace falcon_hwdefs.h with regs.h. The new definitions have been generated according to a naming convention which incorporates the type and revision information. Update the code accordingly.

2009-10-24sfc: Move RX data FIFO thresholds out of struct efx_nic_typeBen Hutchings
Since there are now separate blocks of code to set the thresholds for each NIC type, it is no longer useful to include them in the NIC type description. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-24sfc: Remove versioned bitfield macrosBen Hutchings
These macros are not extensible to more than two NIC types without repetition of register definitions, and they are only used to deal with a few fields in RX_CFG_REG and global events which moved between Falcon rev A1 and B0. Therefore: - Move RX_CFG_REG initialisation into its own function which tests the NIC revision just once - Explicitly test the NIC revision when checking the RX_RECOVERY flag in global events - Merge definitions of RX_XOFF_MAC_EN flag, which did not move - Remove the macro definitions Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

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.

2009-08-26sfc: 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.
