p 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.
p The BCM5700, BCM5701, BCM5703, BCM5704, BCM5714, BCM5717, BCM5719, BCM5720, BCM5762, BCM5780, BCM57765 and BCM57766 chips are capable of supporting jumbo frames.
p The .Nm driver supports the following media types: l -tag -width 1000baseSX t 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. t Cm 10baseT Set 10Mbps operation. The .Xr ifconfig 8 c mediaopt option can also be used to select either .Cm full-duplex or .Cm half-duplex modes. t Cm 100baseTX Set 100Mbps (Fast Ethernet) operation. The .Xr ifconfig 8 c mediaopt option can also be used to select either .Cm full-duplex or .Cm half-duplex modes. t Cm 1000baseT Set 1000baseT operation over twisted pair. Both .Cm full-duplex and .Cm half-duplex modes are supported. t Cm 1000baseSX Set 1000Mbps (Gigabit Ethernet) operation. Both .Cm full-duplex and .Cm half-duplex modes are supported. .El
