This will allow us to change the locking strategy without affecting our driver programming interface or binary interface. For two wireless drivers, remove unnecessary locking, since they don't actually access the multicast address list.

Various counters in ifnet is also updated with these hardware counters.

This saves one register access per each interrupt. Also don't try to process frames when driver is not running.

While I'm here make sure established link is IFM_10_T or IFM_100_TX as bfe(4) just supports 10/100Mbps media.

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. It's not used at all. o Remove BFE_RX_RING_SIZE/BFE_RX_RING_SIZE/BFE_LINK_DOWN.
