The stream channel can be specified by 50.Nm sysctl(8) 51(hw.firewire.fwe.stream_ch). 52.Pp 53This driver supports polling(4) as well if it's compiled with 54DEVICE_POLLING option. 55.Sh HISTORY 56The fwe device driver first appeared in FreeBSD 5.0. 57.Sh BUGS 58This driver emulates ethernet very adhoc way and it doesn't reserve a stream channel using an isochronous manager. 59Note this driver uses very different protocol from RFC2734(IPv4 over IEEE 1394). 60.Sh SEE ALSO 61.Xr arp 4 , 62.Xr firewire 4 , 63.Xr fwohci 4 , 64.Xr netintro 4 , 65.Xr ng_ether 4 , 66.Xr polling 4 , 67.Xr ifconfig 8 , 68.Xr sysctl 8 69.Sh AUTHORS 70.An -nosplit 71The 72.Nm 73driver was written by 74.An Hidetoshi Shimokawa . 75.Pp 76This manual page was written by 77.An Hidetoshi Shimokawa . 78
