The BCM5717, BCM5718, BCM5723, BCM5754, BCM5755, BCM5761, BCM5762, BCM5764, BCM5784, BCM5785, BCM5787 and BCM577xx chips also support IPv6 receive TCP/UDP checksum offload. The .Nm driver supports this feature of the chip. See .Xr ifconfig 8 for information on how to enable this feature. .Pp The BCM5700, BCM5701, BCM5702, BCM5703, BCM5704, BCM5714, BCM5717, BCM5719, BCM5720, BCM5762, BCM5780, BCM57765 and BCM57766 also support jumbo frames, which can be configured via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the .Xr ifconfig 8 utility configures the adapter to receive and transmit Jumbo frames. .Pp The level of interrupt mitigation for received packets can be adjusted with the .Li hw.bge.rx_lvl .Xr sysctl 8 control. A value of 1 yields a .Nm interrupt for every two full-sized Ethernet frames. Each increment of the value will, roughly, halve receive interrupt rate, up to a maximum of 5, which interrupts about every 30 to 40 full-sized TCP segments. .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 ifconfig.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-dupex modes are supported. .It Cm 1000baseSX Set 1000Mbps (Gigabit Ethernet) operation. Both .Cm full-duplex and .Cm half-duplex modes are supported. .El .Pp The .Nm driver supports the following media options: .Bl -tag -width full-duplex .It Cm full-duplex Force full duplex operation. .It Cm half-duplex Force half duplex operation. .El .Pp For more information on configuring this device, see .Xr ifconfig 8 . .Sh DIAGNOSTICS .Bl -diag .It "bge%d: can't find mem space" A fatal initialization error has occurred. .It "bge%d: couldn't map interrupt" A fatal initialization error has occurred. .It "bge%d: watchdog timeout -- resetting" The device has stopped responding to the network, or there is a problem with the network connection (cable). .El .Sh SEE ALSO .Xr arp 4 , .Xr brgphy 4 , .Xr ifmedia 4 , .Xr mii 4 , .Xr netintro 4 , .Xr pci 4 , .Xr ifconfig 8 .Sh HISTORY The .Nm driver first appeared in .Nx 1.6.1 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Bill Paul .Aq wpaul@windriver.com for .Fx and ported to .Nx by .An Frank van der Linden .Aq fvdl@wasabisystems.com , .An Jason R.
