Add le(4), a driver for AMD Am7900 LANCE and Am79C9xx PCnet NICs ported from NetBSD. This driver actually can replace lnc(4). Advantages over lnc(4) are: - Cleaner and more flexible regarding MD needs. - Endian-clean and MPSAFE. - Supports ALTQ, VLAN_MTU, ifmedia. - Uses 32bit DMA for the PCI variants. This commit includes front-ends for the dma(4) pseudo-bus found on SBus- based sparc64 machines (thus supports the on-board LANCE in Sun Ultra 1) and PCI. In order to actually replace lnc(4), the front-ends for ISA and the PC98 CBUS would have to be added but for which I don't have hardware to test. Reviewed and some improvements by: yongari Tested on: i386, sparc64

- Revert if_le_pci.c rev. 1.2; although lnc(4) is now gone, le_pci_probe() still should return BUS_PROBE_LOW_PRIORITY instead of BUS_PROBE_DEFAULT in order to give pcn(4) a chance to attach in case it probes after le(4). - Rearrange the code related to RX interrupt handling so that ownership of RX descriptors is immediately returned to the NIC after we have copied the data of the hardware, allowing the NIC to already reuse the descriptor while we are processing the data in ifp->if_input(). This results in a small but measurable increase in RX throughput. As a side-effect, this moves the workaround for the LANCE revision C bug to am7900.c (still off by default as I doubt we will actually encounter such an old chip in a machine running FreeBSD) and the workaround for the bug in the VMware PCnet-PCI emulation to am79000.c, which is now also only compiled on i386 (resulting in a small increase in RX throughput on the other platforms). - Change the RX interrupt handlers so that the descriptor error bits are only check once in case there was no error instead of twice (inspired by the NetBSD pcn(4), which additionally predicts the error branch as false). - Fix the debugging output of the RX and TX interrupt handlers; while looping through the descriptors print info about the currently processed one instead of always the previously last used one; remove pointless printing of info about the RX descriptor bits after their values were reset. - Create the DMA tags used to allocate the memory for the init block, descriptors and packet buffers with the alignment the respective NIC actually requires rather than using PAGE_SIZE unconditionally. This might as well fix the alignment of the memory as it seems we do not inherit the alignment constraint from the parent DMA tag. - For the PCI variants double the number of RX descriptors and buffers from 8 to 16 as this minimizes the number of RX overflows im seeing with one NIC-mainboard combination. Nevertheless move reporting of overflows under debugging as they seem unavoidable with some crappy hardware. - Set the software style of the PCI variants to ILACC rather than PCnet-PCI as the former is was am79000.c actually implements. Should not make a difference for this driver though. - Fix the driver name part in the MODULE_DEPEND of the PCI front-end for ether. - Use different device descriptions for PCnet-Home and PCnet-PCI. - Fix some 0/NULL confusion in lance_get(). - Use bus_addr_t for sc_addr and bus_size_t for sc_memsize as these are more appropriate than u_long for these. - Remove the unused LE_DRIVER_NAME macro. - Add a comment describing why we are taking the LE_HTOLE* etc approach instead of using byteorder(9) functions directly. - Improve some comments and fix some wording.

#define LE_B20_SSTYLE_ILACC 1 /* ILACC (32-bit) */
Add le(4), a driver for AMD Am7900 LANCE and Am79C9xx PCnet NICs ported from NetBSD. This driver actually can replace lnc(4). Advantages over lnc(4) are: - Cleaner and more flexible regarding MD needs. - Endian-clean and MPSAFE. - Supports ALTQ, VLAN_MTU, ifmedia. - Uses 32bit DMA for the PCI variants. This commit includes front-ends for the dma(4) pseudo-bus found on SBus- based sparc64 machines (thus supports the on-board LANCE in Sun Ultra 1) and PCI. In order to actually replace lnc(4), the front-ends for ISA and the PC98 CBUS would have to be added but for which I don't have hardware to test. Reviewed and some improvements by: yongari Tested on: i386, sparc64
