88.Pp
89The NetXtreme II product family is composed of various Converged NIC (or CNIC)
90Ethernet controllers which support a TCP Offload Engine (TOE),
91Remote DMA (RDMA), and iSCSI acceleration,
92in addition to standard L2 Ethernet traffic,
93all on the same controller.
94The following features are supported in the
95.Nm
96driver under
97.Nx :
98.Bd -literal -offset indent
99IPv4 receive IP/TCP/UDP checksum offload
100Jumbo frames (up to 9022 bytes)
101VLAN tag insertion
102Interrupt coalescing

108.Nm
109driver supports the following media types:
110.Bl -tag -width ".Cm 10baseT/UTP"
111.It Cm autoselect
112Enable autoselection of the media type and options.
113The user can manually override
114the autoselected mode via
115.Xr ifconfig 8 .
116.It Cm 10baseT/UTP
117Set 10Mbps operation.
118The
119.Xr ifconfig 8
120.Ic mediaopt
121option can also be used to select either
122.Cm full-duplex
123or
124.Cm half-duplex
125modes.
126.It Cm 100baseTX
127Set 100Mbps (Fast Ethernet) operation.
128The
129.Xr ifconfig 8
130.Ic mediaopt
131option can also be used to select either
132.Cm full-duplex
133or
134.Cm half-duplex
135modes.
136.It Cm 1000baseTX
137Set 1000baseTX operation over twisted pair.
138Only
139.Cm full-duplex
140mode is supported.
141.It Cm 1000baseSX
142Set 1000Mbps (Gigabit Ethernet) operation.
143Both
144.Cm full-duplex
145and
146.Cm half-duplex
147modes are supported.
