* sfc: Treat all MAC registers as 128-bitBen Hutchings2009-11-26
| | | | | | | | | | Although all the defined fields in these registers are within 32 bits, they are architecturally defined as 128-bit like most other Falcon registers. In particular, we must use efx_reado() to ensure proper locking when reading MD_STAT_REG. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* sfc: Fix descriptor cache sizesBen Hutchings2009-11-26
| | | | | | | | These were accidentally undersized by a factor of 2, which limited performance. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | Define name tables for these enumerations in a similar way as for loopback. Move the loopback name table together with them. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* sfc: Combine high-level header filesBen Hutchings2009-11-24
| | | | | | | | | All files that include ethtool.h, rx.h or tx.h are also including efx.h, and there is no good reason to separate out the few declarations they contain. Therefore fold them into efx.h. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* sfc: Move definition of struct falcon_nic_data into falcon.hBen Hutchings2009-11-24
| | | | | | | | This is preparation for moving Falcon-specific state required by other Falcon-specific code. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* sfc: Make board information explicitly Falcon-specificBen Hutchings2009-11-24
| | | | | | | | | | | | Rename struct efx_board to struct falcon_board. Introduce and use inline function to look up board info from struct efx_nic, in preparation for moving it. Move board init and fini calls into NIC probe and remove functions. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* sfc: Rename efx_board::init_leds to init_phy and use for SFN4111TBen Hutchings2009-11-24
| | | | | | | | | | | efx_board::init_leds was introduced as a second stage of initialisation because of the inter-dependency between the board and PHY. We want to move board initialisation into NIC probing, which is too early to use MDIO, so SFN4111T initialisation also needs to be split.

* sfc: Use a single blink implementationBen Hutchings2009-11-24
| | | | | | | | | | | Only some PHYs have firmware support for a LED blink mode, so we currently blink the others in a timer function. Since all PHYs have simple on and off modes, we don't gain anything by using multiple blink implementations. Also, since we have a process context there is no need to use a timer.

* sfc: Move assertions and buffer cleanup earlier in efx_rx_packet_lro()Ben Hutchings2009-11-24
| | | | | | | | This removes the need to use a label and goto, and makes the two branches mirror each other more closely. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * i2c: Add an interface to lock/unlock an I2C bus segmentJean Delvare2009-11-07
| | | | | | | | | | | | | | | | | | Some drivers need to be able to prevent access to an I2C bus segment for a specific period of time. Add an interface for them to do so without twiddling with i2c-core internals. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Ben Hutchings <bhutchings@solarflare.com>
* | sfc: Enable heuristic selection between page and skb RX buffersBen Hutchings2009-10-30
| | | | | | | | | | | | | | | | 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>
* | sfc: Feed GRO result into RX allocation policy and interrupt moderationBen Hutchings2009-10-30
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * sfc: Set ip_summed correctly for page buffers passed to GROBen Hutchings2009-10-28
| | | | | | | | | | | | | | | | | | | | 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>
* | sfc: Really allow RX checksum offload to be disabledBen Hutchings2009-10-28
| | | | | | | | | | | | | | | | | | | | 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>
* | sfc: Rename 'xfp' file and functions to reflect realityBen Hutchings2009-10-24
| | | | | | | | | | | | | | | | | | | | 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.

* | sfc: Remove unused code for non-autoneg speed/duplex switchingBen Hutchings2009-10-24
| | | | | | | | | | | | | | | | 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>
* | sfc: Merge efx_fc_resolve() into efx_mdio_get_pause()Ben Hutchings2009-10-24
| | | | | | | | | | | | | | | | 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>
* | sfc: Move MTD probe after netdev registration and name allocationBen Hutchings2009-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | 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(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
