* mv643xx_eth: add PHY-less modeLennert Buytenhek2008-06-12
| | | | | | | | | | On some boards, the mv643xx_eth MAC isn't connected to a PHY but directly (via the MII/GMII/RGMII interface) to another MAC-layer device. This patch allows specifying ->phy_addr = -1 to skip all PHY-related initialisation and run-time poking in that case.

* mv643xx_eth: be more agressive about RX refillLennert Buytenhek2008-06-12
| | | | | | | | | During OOM, instead of stopping RX refill when the rx desc ring is not empty, keep trying to refill the ring as long as it is not full instead. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Dale Farnsworth <dale@farnsworth.org>
* mv643xx_eth: detect alternate TX BW control register locationLennert Buytenhek2008-06-12
| | | | | | | | | | Some SoCs have the TX bandwidth control registers in a slightly different place. This patch detects that case at run time, and re-directs accesses to those registers to the proper place at run time if needed.

* mv643xx_eth: detect extended rx coal register fieldLennert Buytenhek2008-06-12
| | | | | | | | | | Newer hardware has a 16-bit instead of a 14-bit RX coalescing count field in the SDMA_CONFIG register. This patch adds a run-time check for which of the two we have, and adjusts further writes to the rx coal count field accordingly.

* mv643xx_eth: work around TX hang hardware issueLennert Buytenhek2008-06-12
| | | | | | | | | | | Under some conditions, the TXQ ('TX queue being served') bit can clear before all packets queued for that TX queue have been transmitted. This patch enables TXend interrupts, and uses those to re-kick TX queues that claim to be idle but still have queued descriptors from the interrupt handler.

* mv643xx_eth: allow multiple TX queuesLennert Buytenhek2008-06-12
| | | | | | | | | | | As with the multiple RX queue support, allow the platform code to specify that the hardware we are running on supports multiple TX queues. This patch only uses the highest-numbered enabled queue to send packets to for now, this can be extended later to enable QoS and such.

* mv643xx_eth: allow multiple RX queuesLennert Buytenhek2008-06-12
| | | | | | | | | | Allow the platform code to specify that we are running on hardware that is capable of supporting multiple RX queues. If this option is used, initialise all of the given RX queues instead of just RX queue zero. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Dale Farnsworth <dale@farnsworth.org>
* mv643xx_eth: add tx rate controlLennert Buytenhek2008-06-12
| | | | | | | | | Add an interface for the hardware's per-port and per-subqueue TX rate control. In this stage, this is mainly so that we can disable the bandwidth limits during initialisation of the port.

* mv643xx_eth: general cleanupLennert Buytenhek2008-06-12
| | | | | | | | | General cleanup of the mv643xx_eth driver. Mainly fixes coding style / indentation issues, get rid of some useless 'volatile's, kill some more superfluous comments, and such. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Dale Farnsworth <dale@farnsworth.org>
* mv643xx_eth: remove write-only interrupt coalescing variablesLennert Buytenhek2008-06-12
| | | | | | | | | | Remove the write-only ->[rt]x_int_coal members from struct mv643xx_eth_private. In the process, tweak the RX/TX interrupt mitigation code so that it is compiled by default, and set the default coalescing delays to 0 usec.

* mv643xx_eth: kill private unused instance of struct net_device_statsLennert Buytenhek2008-06-12
| | | | | | | | | | | | The per-port mv643xx_eth_private struct had a private instance of struct net_device_stats that was never ever written to, only read (via the ethtool statistics interface). This patch gets rid of the private instance, and tweaks the ethtool statistics code in mv643xx_eth to use the statistics in struct net_device instead.

* mv643xx_eth: kill FUNC_RET_STATUS/pkt_infoLennert Buytenhek2008-06-12
| | | | | | | | | Since they are no longer used, kill enum FUNC_RET_STATUS and struct pkt_info (which were a rather roundabout way of communicating RX/TX status within the same driver). Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Dale Farnsworth <dale@farnsworth.org>
* mv643xx_eth: move rx_return_buff() into its only callerLennert Buytenhek2008-06-12
| | | | | | | | | rx_return_buff() is also a remnant of the HAL layering that the original mv643xx_eth driver used. Moving it into its caller kills the last reference to FUNC_RET_STATUS/pkt_info. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Dale Farnsworth <dale@farnsworth.org>
* mv643xx_eth: move port_receive() into its only callerLennert Buytenhek2008-06-12
| | | | | | | | | | The port_receive() function is a remnant of the original mv643xx_eth HAL split. This patch moves port_receive() into its caller, so that the top and the bottom half of RX processing no longer communicate via the HAL FUNC_RET_STATUS/pkt_info mechanism abstraction anymore.

* mv643xx_eth: kill superfluous commentsLennert Buytenhek2008-06-12
| | | | | | | | | | Half of the functions in the mv643xx_eth driver are prefixed by useless and baroque comment blocks on _what_ those functions do (which is obvious from the code itself) rather than why, and there's no point in keeping those comments around.

* mv643xx_eth: use 'mv643xx_eth_' prefix consistentlyLennert Buytenhek2008-06-12
| | | | | | | | | | | A bunch of places in the mv643xx_eth driver use the 'mv643xx_' prefix. Since the mv643xx is a chip that includes more than just ethernet, this patch makes all those places use either no prefix (for some internal-use-only functions), or the full 'mv643xx_eth_' prefix.

* mv643xx_eth: get rid of ETH_/ethernet_/eth_ prefixesLennert Buytenhek2008-06-12
| | | | | | | | | | The fact that mv643xx_eth is an ethernet driver is pretty obvious, and having a lot of internal-use-only functions and defines prefixed with ETH_/ethernet_/eth_ prefixes is rather pointless. So, get rid of most of those prefixes. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Dale Farnsworth <dale@farnsworth.org>

| * tg3: Fix 5761 WOLMatt Carlson2008-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 5761 non-e devices, two problems prevent the administrator from overriding the WOL settings in the device's NVRAM. The first problem is that GPIO 0 and GPIO 2 have been swapped. This change prevented the administrator from turning on WOL when it is disabled in NVRAM. The fix is to add a new path for the 5761 that swaps the two GPIOs in the code as well. The second problem is that GPIO 1 could not be toggled by the driver because the GPIO is shared with the debug UART GPIO. This will prevent the administrator from being able to turn WOL off if it was enabled in NVRAM. The fix is to always disable the debug UART after a GRC reset.
