>Description:
I'm using a cajun switch P333T with a gigabit copper module. In my
FreeBSD I have a wx driver:
wx0: <Intel PRO/1000 T Gigabit Ethernet> mem 0xeb020000-0xeb02ffff,0xeb000000-0xeb01ffff irq 2 at device 4.0 on pci2
miibus0: <MII bus> on wx0
e1000phy0: <Marvell Semiconductor 88E1000* gigabit PHY> on miibus0
e1000phy0:  1000baseTX-FDX, 100baseTX-FDX, 100baseTX, 10baseTX-FDX, 10baseTX, auto
wx0: Ethernet address 00:03:47:72:38:ca
It worked well in 100Mbs, but if I connect this in a gigabit copper (cat 5)
cable, all the packets that is even disapears without seen in the
tcpdump stuff. Seems to me similar to a problem found in http://www.cisco.com/warp/public/770/fn13054.shtml
that is similar to this.
>How-To-Repeat:
ping -s 72 <machine with a wx driver>
works
ping -s 73 <machine with a wx driver>
don't work.

>Fix:
If someone know how to solve this problem, please help-me. I can help
doing tests.
