[problems netbooting machines between fxp and em NICs]

Hello,

I am too seeing problems jumpstarting a machine (client) using a fxp NIC from 
a server (runnning 5.1-Rel) using an em NIC : the em NIC is wired down as 
100baseTX full-duplex, but the 5.1-Release kernel seems unable to see it and 
tries to use a half-duplex setting (this surprisingly works when loading the 
install bits via ftp, with a rate of around 44kB/s, but fails completely when 
NFS is selected as install media).

Everything works finer after switching virtual consoles on the client and 
"ifconfig'ing" the fxp1 as full-duplex, from the holographic shell. What is 
even more startling is that the same fxp1 is correctly set up as full duplex 
with the 4.8-RELEASE install kernel (from the same boot server, with the same 
setup for its NIC : I've installed two tftpboot directories so as to select 
which release is loaded via PXE).

On monday , I'll try to wire the server em NIC as half-duplex to see wether 
the client fxp1 has a better throughput (afterwards, I'll try and look for 
differences in the 4.8 and 5.1 fxp drivers).

	Happy hacking
