fxp performance with POLLING

[Bartosz Stec]

Hello again :)

With POLLING enabled I experience about 10%-25% performance drop when 
copying files over network. Tested with both SAMBA and NFS. Is it normal?

    FreeBSD 7.1-PRERELEASE #0: Sat Sep  6 01:52:12 CEST 2008
    fxp0: <Intel 82801DB (ICH4) Pro/100 Ethernet> port 0xc800-0xc83f mem
    0xe1021000-0xe1021fff irq 20 at device 8.0 on pci1

    # ifconfig fxp0
    fxp0: flags=9843<UP,BROADCAST,RUNNING,SIMPLEX,LINK0,MULTICAST>
    metric 0 mtu 1500
            options=8<VLAN_MTU>
            ether 00:20:ed:42:87:13
            inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255
            media: Ethernet autoselect (100baseTX <full-duplex>)
            status: active

BTW overall SAMBA performance still sucks on 7.1-pre as much as on 
RELENG_5 ...:( - 7.5 MB/s peak.
