38.\" 39.Dd January 30, 2006 40.Dt LE 4 41.Os 42.Sh NAME 43.Nm le 44.Nd "AMD Am7900 LANCE and Am79C9xx PCnet Ethernet interface driver" 45.Sh SYNOPSIS --- 28 unchanged lines hidden (view full) --- 74chip set. 75.Pp 76The 77.Nm 78driver also supports PCnet adapters based on the 79.Tn AMD 79C9xx 80family of chips, which are single-chip implementations of a 81.Tn LANCE |
82chip and a DMA engine. 83This includes a superset of the |
84.Tn PCI |
85bus Ethernet chip sets supported by the |
86.Xr pcn 4 87driver. 88The 89.Nm |
90driver treats all of these 91.Tn PCI 92bus Ethernet chip sets as an 93.Tn AMD Am79C970 PCnet-PCI 94and does not support the additional features like the MII bus and burst mode of 95.Tn AMD Am79C971 PCnet-FAST 96and greater chip sets. 97Thus the |
98.Xr pcn 4 |
99driver should be preferred for the latter. |
100.Pp 101The 102.Nm 103driver supports reception and transmission of extended frames for 104.Xr vlan 4 . 105Selective reception of multicast Ethernet frames is provided by a 64-bit mask; 106multicast destination addresses are hashed to a bit entry using the Ethernet 107CRC function. --- 270 unchanged lines hidden --- |
