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
83.Tn PCI
84bus interface.
85This includes most of the adapters which are also supported by the
86.Xr pcn 4
87driver.
88The
89.Nm
90driver does not support all features of these adapters however, thus the
91.Xr pcn 4
92driver should be preferred.
93.Pp
94The
95.Nm
96driver supports reception and transmission of extended frames for
97.Xr vlan 4 .
98Selective reception of multicast Ethernet frames is provided by a 64-bit mask;
99multicast destination addresses are hashed to a bit entry using the Ethernet
100CRC function.
