offload for receive, 119IP checksum offload for transmit, VLAN tag insertion and stripping, 120as well as a 256-bit multicast hash filter. 121The BCM5717, BCM5718, BCM5723, BCM5724, BCM5754, BCM5755, BCM5761, BCM5764, 122BCM5784, BCM5785, BCM5787 and BCM577xx chips also support IPv6 receive TCP/UDP 123checksum offload. 124.Pp 125The BCM5700, BCM5701, BCM5703 and BCM5704 chips are capable of 126supporting Jumbo frames, which can be configured via the 127interface MTU setting. 128Selecting an MTU larger than 1500 bytes with the 129.Xr ifconfig 8 130utility configures the adapter to receive and transmit Jumbo frames. 131Using Jumbo frames can greatly improve performance for certain tasks, 132such as file transfers and data streaming. 133.Pp 134The 135.Nm 136driver supports the following media types: 137.Bl -tag -width 1000baseSX 138.It Cm autoselect 139Enable autoselection of the media type and options. 140The user can manually override 141the autoselected mode by adding media options to the appropriate 142.Xr hostname.if 5 143file. 144.It Cm 10baseT 145Set 10Mbps operation. 146The 147.Xr ifconfig 8 148.Ic mediaopt 149option can also be used to select either 150.Cm full-duplex 151or 152.Cm half-duplex 153modes. 154.It Cm 100baseTX 155Set 100Mbps (Fast Ethernet) operation. 156The 157.Xr ifconfig 8 158.Ic mediaopt 159option can also be used to select either 160.Cm full-duplex 161or 162.Cm half-duplex 163modes. 164.It Cm 1000baseT 165Set 1000baseT operation over twisted pair. 166Both 167.Cm full-duplex 168and 169.Cm half-dupex 170modes are supported. 171.It Cm 1000baseSX 172Set 1000Mbps (Gigabit Ethernet) operation. 173Both 174.Cm full-duplex 175and 176.Cm half-duplex 177modes are supported. 178.El 179.Pp 180The 181.Nm 182driver supports the following media
