r200904: Don't reinitialize controller if driver is already running. This reduces number of link state UP/DOWN changes. r200905: Reimplement controller reset. Datasheet says full reset takes about 1ms. Since we switched to memory register mapping make sure to flush PCI posted write by reading the register again. While I'm here add additional delays in loop while driver waits the completion of the reset. r200906: Overhaul RX filter programming. o Let RX filter handler program promiscuous/multicast filter as well as broadcasting. o Remove unnecessary register access. o Simplify ioctl handler and have set_rxfilter to handle IFF_PROMISC and IFF_ALLMULTI change instead of directly programming the controller. o Removed unnecessary error variable reinitialization in ioctl handler. o Add IFF_DRV_RUNNING check before programming multicast filter. o Configure maximum allowed frame length before enabling MAC. Datasheet didn't say the exact ordering of programming sequence but it looks more natural to set maximum allowed frame length first prior to enabling controller. r200907: Don't report link status if driver is not running. r200908: Report the correct result of mii_mediachg(). Previously it always used to return success without respect to the result. While I'm here use mii_mediachg() in ste_init_locked which allows driver to use currently configured media. ste_ifmedia_upd() is supposed to be called whenever user changes current media settings. r200910: Implement hardware MAC statistics counter support. The counters could be accessed with dev.ste.0.stats sysctl node. r200911: Remove unused duplicated register definition. It seems the definition was made to access STE_ASICCTL register as 16bits but ste(4) always access the register as 32bits so it was never used before. r200912: Correct STE_COUNTDOWN register offset. The datasheet was wrong. r200913: We don't need to generate DMA complete interrupt for every transmitted frames. So request interrupt for every 16th frames. Due to the limitation of hardware we can't suppress the interrupt as driver should have to check TX status register. The TX status register can store up to 31 TX status so driver can't send more than 31 frames without reading TX status register. With this change controller would not generate TX completion interrupt for every frame, so reclaim transmitted frames in ste_tick(). |
