* Add basic WOL support for 82550/82551/82558 and 82559 basedPyun YongHyeon2008-11-273-11/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | controllers. ICH based controllers are treated as 82559. 82557, earlier revision of 82558 and 82559ER have no WOL capability. o WOL support requires help of a firmware so add check whether hardware is capable of handling magic frames by reading EEPROM. o Enable accepting WOL frames only when hardware is about to suspend or shutdown. Previously fxp(4) used to allow receipt of magic frame under normal operation mode which could cause hardware hang if magic frame is received by hardware. Datasheet clearly states driver should not allow WOL frames under normal operation mode. o Disable WOL frame reception in device attach so have fxp(4) immunize against system hang which can be triggered by magic packets when the hardware is not in fully initialized state. o Don't reset all hardware configuration data in fxp_stop() otherwise important configuration data is lost and this would reset WOL configuration to default state which in turn cause hardware hang on receipt of magic frames. To fix the issue, preserve hardware configuration data by issuing a selective reset. o Explicitly disable interrupts after issuing selective reset as reset may unmask interrupts.

* Implement TSO for 82550/82551 controllers.Pyun YongHyeon2008-11-263-14/+118
| | | | | | | | | | | | | | | | | | | | | | | | | o Configure controller to use dynamic TBD as TSO requires that operation mode. o Add a dummy TBD to tx_cb_u as TSO can access one more TBD in TSO operation. o Increase a DMA segment size to 4096 to hold a full IP segment with link layer header. o Unlike other TSO capable controllers, 82550/82551 does not modify the first IP packet in TSO operation so driver should create an IP packet with proper header. Subsequent IP packets are generated from the header information in the first IP packet header. Likewise pseudo checksum also should be computed by driver for the first packet. o TSO requires one more TBD to hold total TCP payload. To make code simple for TSO/non-TSO case, increase the index of the first available TBD array. o Remove KASSERT that checks the size of a DMA segment should be less than or equal to MCLBYTES as it's no longer valid in TSO. o Tx threshold and number of TBDs field is used to store MSS in TSO. So don't set the Tx threshold in TSO case. Notes: svn path=/head/; revision=185330
* Implement Rx checksum offload for 82559 or later controllers.Pyun YongHyeon2008-11-262-28/+110
| | | | | | | | | | | | | | | | 82559 or later controllers added simple checksum calculation logic in RU. For backward compatibility the computed checksum is appended at the end of the data posted to Rx buffer. This type of simple checksum calculation support had been used on several vendors such as Sun HME/GEM, SysKonnect GENESIS and Marvell Yukon controllers. Because this type of checksum offload support requires parsing of received frame and pseudo checksum calculation with software routine it still consumes more CPU cycles than that of full-fledged checksum offload controller. But it's still better than software checksum calculation. Notes: svn path=/head/; revision=185329
* o Introduce a new function, fxp_new_rfabuf which allocates a newPyun YongHyeon2008-11-261-27/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rx buffer and loads DMA map. Also add a function fxp_discard_rfabuf that handles reusing Rx buffer/DMA map. With this change fxp_add_rfabuf just handles appending a new RFA to existing chain. o Initialize mbuf length in fxp_new_rfabuf. o Don't reset rnr and have fxp(4) handle received frames even if it couldn't allocate new Rx buffer. This will make fxp(4) reload updated RFA under rnr case. The rnr would still be reset to 0 if polling is active and fxp(4) processed number of allowed Rx events. o Update if_iqdrops if fxp(4) couldn't allocate Rx buffer. Previously fxp(4) used to try to reuse Rx buffer when new buffer allocation is failed. But fxp(4) didn't take into account loaded DMA map such that the same DMA map was loaded again without unloading the map. There is no reason to unload the loaded map and reload the same map again, just reusing the map is enough. I believe the spare DMA map in softc was introduced to implement this behaviour. Also fxp(4) used to stop Rx processing if once Rx buffer allocation or DMA map load fails which in turn resulted in losing incoming frames under heavy network load. With this change fxp(4) should survive from resource shortage condition. Notes: svn path=/head/; revision=185328

| | | | | | | | | | | | | | | | | | | | | | | | IFF_DRV_OACTIVE to note resource shortage to upper stack. - Don't count number of mbuf chains. Default 32 DMA segments for a frame is enough for most cases. If bus_dmamap_mbuf_sg fails use m_collapse(9) to collapse the mbuf chain instead of relying on expensive m_defrag(9). - Move bpf handling to fxp_start_body() which is supposed to be more appropriate place. - Always arm watchdog timer whenever a new Tx request is made. Previously fxp(4) used to arm watchdog timer only when FXP_CXINT_THRESH-th Tx request is made. Because fxp(4) does not rely on Tx interrupt to reclaim transmitted mbufs it's better to arm watchdog timer to detect potential lockups. - Add more aggresive Tx buffer reclaiming in fxp_start_body to make room for new Tx requests. Since fxp(4) does not request Tx completion interrupt for every frames it's necessary to clean TXCBs in advance to saturate link. - Make fxp(4) try to start more packets transmitting regardless of interrupt type in fxp_intr_body.

This fixes problem with idle polling. o Make registration and deregistration from polling in a functional way, insted of next tick/interrupt. o Obsolete kern.polling.enable. Polling is turned on/off with ifconfig. Detailed kern_poll.c changes: - Remove polling handler flags, introduced in 1.21. The are not needed now. - Forget and do not check if_flags, if_capenable and if_drv_flags. - Call all registered polling handlers unconditionally. - Do not drop poll_mtx, when entering polling handlers. - In ether_poll() NET_LOCK_GIANT prior to locking poll_mtx. - In netisr_poll() axe the block, where polling code asks drivers to unregister. - In netisr_poll() and ether_poll() do polling always, if any handlers are present. - In ether_poll_[de]register() remove a lot of error hiding code. Assert that arguments are correct, instead. - In ether_poll_[de]register() use standard return values in case of error or success. - Introduce poll_switch() that is a sysctl handler for kern.polling.enable. poll_switch() goes through interface list and enabled/disables polling. A message that kern.polling.enable is deprecated is printed. Detailed driver changes: - On attach driver announces IFCAP_POLLING in if_capabilities, but not in if_capenable. - On detach driver calls ether_poll_deregister() if polling is enabled. - In polling handler driver obtains its lock and checks IFF_DRV_RUNNING flag. If there is no, then unlocks and returns. - In ioctl handler driver checks for IFCAP_POLLING flag requested to be set or cleared. Driver first calls ether_poll_[de]register(), then obtains driver lock and [dis/en]ables interrupts. - In interrupt handler driver checks IFCAP_POLLING flag in if_capenable. If present, then returns.This is important to protect from spurious interrupts. Reviewed by: ru, sam, jhb Notes: svn path=/head/; revision=150789

| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.
