| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove unused and easy to misuse PNP macro parameter Inspired by r338025, just remove the element size parameter to the MODULE_PNP_INFO macro entirely. The 'table' parameter is now required to have correct pointer (or array) type. Since all invocations of the macro already had this property and the emitted PNP data continues to include the element size, there is no functional change.

* - Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOPMarius Strobl2011-05-031-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (reporting IFM_LOOP based on BMCR_LOOP is left in place though as it might provide useful for debugging). For most mii(4) drivers it was unclear whether the PHYs driven by them actually support loopback or not. Moreover, typically loopback mode also needs to be activated on the MAC, which none of the Ethernet drivers using mii(4) implements. Given that loopback media has no real use (and obviously hardly had a chance to actually work) besides for driver development (which just loopback mode should be sufficient for though, i.e one doesn't necessary need support for loopback media) support for it is just dropped as both NetBSD and OpenBSD already did quite some time ago. - Let mii_phy_add_media() also announce the support of IFM_NONE. - Restructure the PHY entry points to use a structure of entry points instead of discrete function pointers, and extend this to include a "reset" entry point. Make sure any PHY-specific reset routine is always used, and provide one for lxtphy(4) which disables MII interrupts (as is done for a few other PHYs we have drivers for). This includes changing NIC drivers which previously just called the generic mii_phy_reset() to now actually call the PHY-specific reset routine, which might be crucial in some cases. While at it, the redundant checks in these NIC drivers for mii->mii_instance not being zero before calling the reset routines were removed because as soon as one PHY driver attaches mii->mii_instance is incremented and we hardly can end up in their media change callbacks etc if no PHY driver has attached as mii_attach() would have failed in that case and not attach a miibus(4) instance. Consequently, NIC drivers now no longer should call mii_phy_reset() directly, so it was removed from EXPORT_SYMS. - Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe(). The purpose of that function is to perform the common steps to attach a PHY driver instance and to hook it up to the miibus(4) instance and to optionally also handle the probing, addition and initialization of the supported media. So all a PHY driver without any special requirements has to do in its bus attach method is to call mii_phy_dev_attach() along with PHY-specific MIIF_* flags, a pointer to its PHY functions and the add_media set to one. All PHY drivers were updated to take advantage of mii_phy_dev_attach() as appropriate. Along with these changes the capability mask was added to the mii_softc structure so PHY drivers taking advantage of mii_phy_dev_attach() but still handling media on their own do not need to fiddle with the MII attach arguments anyway. - Keep track of the PHY offset in the mii_softc structure. This is done for compatibility with NetBSD/OpenBSD. - Keep track of the PHY's OUI, model and revision in the mii_softc structure. Several PHY drivers require this information also after attaching and previously had to wrap their own softc around mii_softc. NetBSD/OpenBSD also keep track of the model and revision on their mii_softc structure. All PHY drivers were updated to take advantage as appropriate. - Convert the mebers of the MII data structure to unsigned where appropriate. This is partly inspired by NetBSD/OpenBSD. - According to IEEE 802.3-2002 the bits actually have to be reversed when mapping an OUI to the MII ID registers. All PHY drivers and miidevs where changed as necessary. Actually this now again allows to largely share miidevs with NetBSD, which fixed this problem already 9 years ago. Consequently miidevs was synced as far as possible. - Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that weren't explicitly converted to support flow control before. It's unclear whether flow control actually works with these but typically it should and their net behavior should be more correct with these changes in place than without if the MAC driver sets MIIF_DOPAUSE.

| | | | | | | | | | | | | | | | | | | | | | | | | | the NIC drivers as well as the PHY drivers to take advantage of the mii_attach() introduced in r213878 to get rid of certain hacks. For the most part these were: - Artificially limiting miibus_{read,write}reg methods to certain PHY addresses; we now let mii_attach() only probe the PHY at the desired address(es) instead. - PHY drivers setting MIIF_* flags based on the NIC driver they hang off from, partly even based on grabbing and using the softc of the parent; we now pass these flags down from the NIC to the PHY drivers via mii_attach(). This got us rid of all such hacks except those of brgphy() in combination with bce(4) and bge(4), which is way beyond what can be expressed with simple flags. While at it, I took the opportunity to change the NIC drivers to pass up the error returned by mii_attach() (previously by mii_phy_probe()) and unify the error message used in this case where and as appropriate as mii_attach() actually can fail for a number of reasons, not just because of no PHY(s) being present at the expected address(es).

Remove ETHER_ALIGN alignment restriction in Tx/Rx buffers. - created a spare Rx dma map which would be used to cope with failure of loading a dma map. - make sure to load full Tx/Rx descriptor size for Tx/Rx descriptor dma maps, previously bfe(4) used to load single descriptor size for each descriptor rings. I have no idea how it could be run without problems. - don't blindly cast bus_addr_t type to 32bits in bfe_dma_map(). - created bfe_dma_free() to free allocated dma memory/tags. - make sure to invoke bus_dmamap_sync(9) before/after processing descriptor rings/buffers. Because the hardware has severe dma address space limitation, bounce-buffers would be always used on systems with more than 1GB memory during descriptors/buffers access. - added Tx descriptor ring initialization function, bfe_list_tx_init(). - moved producer/consumer index initialization to bfe_list_tx_init() and bfe_list_rx_init() from bfe_chip_reset(). - added bfe_discard_buf() which will update loaded descriptors without unloading/reloading the dma map to speed up error recovery. - implemented Tx side bus_dmamap_load_mbuf_sg(9). The number of segments allowed was chosen to be 16 which should be enough for non-TSO capable hardwares. Setting SOF bit of Tx descriptor is done in the last to avoid potential race. - don't give up sending frames in bfe_start() until the hardware lacks free descriptors. - added XXX comment to second kick command and possible workaround. - implemented Rx side bus_dmamap_load_mbuf_sg(9). - removed bfe_dma_map_desc() as it's not needed anymore after the conversion to bus_dmamap_load_mbuf_sg(9). - added endianness support. With this change bfe(4) should work on any architectures that can create bounce buffers within 1GB address range. - add missing bus_dmamap_sync() in bfe_tx_eof()/bfe_rx_eof(). o Use PCI_BAR instead of hardcoded value to set BARs. Simplified register access with bus_write_4(9)/bus_read_4(9) and removed bfe_btag, bfe_bhandle, bfe_vhandle in softc as it's not used anymore. o Reorder device detach logic such that bfe_detach() is also used for handling driver attach failure case. o Remove unnecessary KASSERT in bfe_detach(). o Remove bfe_rx_cnt, bfe_up, bfe_vpd_prodname, bfe_vpd_readonly in softc.

Prior to this change, it was just luck that 512 count RX/TX lists were properly aligned. Now we can use any size of RX/TX lists and still have them properly aligned. #2 ensures that we don't get into an endless interrupt storm if busdma fails us. Descriptor Protocol Error would occur if we misaligned the TX/RX rings, and Descriptor Error would occur if we tried to give the card descriptors or rings with addresses > 1G. Trying to reinitialize the card isn't going to fix these errors, hence we don't try. Notes: svn path=/head/; revision=159013

| | | | | | | | | | | | | | | | | IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-102-19/+29
| | | | | | | | | | | | | | | | | | | | | | | 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.
