The following sysctls regulate this behaviour (separately +for each path): +.Bl -tag -width indent +.It Va dev.mge.X.int_coal.rx_time +.It Va dev.mge.X.int_coal.tx_time +.Pp +Value of 0 disables IC on the given path, value greater than zero corresponds +to a real time period and is expressed in units equivalent to 64 ticks of the +MGE clock. Maximum allowed value depends on MGE hardware revision. User +provided values larger than supported will be trimmed to the maximum +supported. More details are available in the reference manual of the device. +.El +.Sh HARDWARE +Gigabit Ethernet controllers built into the following Marvell systems-on-chip +are known to work with the +.Nm +driver: +.Pp +.Bl -bullet -compact +.It +Orion 88F5182 +.It +Orion 88F5281 +.It +Kirkwood 88F6281 (MGE V2) +.It +Discovery MV78100 (MGE V2) +.El +.Pp +There are also Marvell system controllers for PowerPC processors, which +include a variation of this gigabit Ethernet module integrated on chip, and +they should also work with the +.Nm +driver, but this wasn't tested: +.Pp +.Bl -bullet -compact +.It +MV64430 +.It +MV64460, MV64461, MV64462 +.El +.Sh SEE ALSO +.Xr altq 4 , +.Xr arp 4 , +.Xr miibus 4 , +.Xr netintro 4 , +.Xr ng_ether 4 , +.Xr polling 4 , +.Xr vlan 4 , +.Xr ifconfig 8 +.Sh HISTORY +The +.Nm +device driver first appeared in +.Fx 8.0 . +.Sh AUTHORS +.An -nosplit +The base version of +.Nm +device driver was written by +.An Grzegorz Bernacki. +It has been extended with advanced features (polling, interrupt coalescing, +multicast, h/w checksum calculation etc.) by +.An Piotr Ziecik . +This manual page was written by +.An Rafal Jaworowski .
