CPU is fast enough to saturate 100Mbps link with this controller and your bottle-neck would be PCI bus because you would use 4 ethernet controllers at the same time. > But in my case scenario I am building a router with WiFi access point > and this particular device allows me to do it on mini-ITX board ( > single PCI slot ). > > Again ...

I made slight change to original patch so the tunable is now set in /boot/loader.conf instead of /boot/device.hints. You can get the same effect by adding the following line to /boot/loader.conf file. dev.rl.0.prefer_iomap="0" # for rl0 dev.rl.1.prefer_iomap="0" # for rl1 dev.rl.3.prefer_iomap="0" # for rl3 Thanks for testing and reporting! > Regards, > Nikola > > On Fri, Aug 20, 2010 at 7:40 PM, Pyun YongHyeon <pyunyh@gmail.com> wrote: > > On Fri, Aug 20, 2010 at 01:44:20PM +0200, Nikola Kalpazanov wrote: > >> Hi, > >> > >> First I want to start with the note that I know Realtek is no good, > >> yet I will appreciate any assistance that you may provide. > >> > >> here are details of the problem: > >> > >> P811B is 4 port Ethernet card with built-in mini-PCI slot where I have > >> attached Atheros 802.11a/b/g/n Wireless PCI Adapter (AR5416). > >> That also requires to disable 4th port from the jumpers on the card. > >> > >> I have installed FreeBSD 8.1-RELEASE i386 > >> > >> pciconf -vlb > >> > >> pcib6@pci0:5:0:0: ? ? ? class=0x060400 card=0x00000000 chip=0x814812d8 > >> rev=0x00 hdr=0x01 > >> ? ? vendor ? ? = 'Pericom Semiconductor' > >> ? ? class ? ? ?= bridge > >> ? ? subclass ? = PCI-PCI > >> rl0@pci0:6:8:0: class=0x020000 card=0x813910ec chip=0x813910ec rev=0x10 hdr=0x00 > >> ? ? vendor ? ? = 'Realtek Semiconductor' > >> ? ? device ? ? = 'Realtek RTL8139 Family PCI Fast Ethernet NIC > >> (RTL-8139/8139C/8139D)' > >> ? ? class ? ? ?= network > >> ? ? subclass ? = ethernet > >> ? ? bar ?
