+The
+.Nm
+driver supports IPv4 receive IP/TCP/UDP checksum offload and transmit IP/TCP
+checksum offload, VLAN tag insertion and stripping,
+as well as a 256-bit multicast hash filter.
+The BCM5717, BCM5718, BCM5723, BCM5754, BCM5755, BCM5761, BCM5764, BCM5784,
+BCM5785, BCM5787 and BCM577xx chips also support IPv6 receive TCP/UDP
+checksum offload.

+BCM5762, BCM5780, BCM57765 and BCM57766
+chips are capable of supporting jumbo frames.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Bl -tag -width 1000baseSX
+.It Cm autoselect
+Enable autoselection of the media type and options.
+The user can manually override
+the autoselected mode by adding media options to the appropriate
+.Xr hostname.if 5
+file.
+.It Cm 10baseT
+Set 10Mbps operation.
+The
+.Xr ifconfig 8
+.Ic mediaopt
+option can also be used to select either
+.Cm full-duplex
+or
+.Cm half-duplex
+modes.
+.It Cm 100baseTX
+Set 100Mbps (Fast Ethernet) operation.
+The
+.Xr ifconfig 8
+.Ic mediaopt
+option can also be used to select either
+.Cm full-duplex
+or
+.Cm half-duplex
+modes.
+.It Cm 1000baseT
+Set 1000baseT operation over twisted pair.
+Both
+.Cm full-duplex
+and
+.Cm half-duplex
+modes are supported.
+.It Cm 1000baseSX
+Set 1000Mbps (Gigabit Ethernet) operation.
+Both
+.Cm full-duplex
