Code Issues Releases Activity

Add le(4), a driver for AMD Am7900 LANCE and Am79C9xx PCnet NICs ported

Browse Source 
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
